BEGALI SIMPLEX BASIC

 CHOOSING THE RIGHT MORSE KEY  

I always remember when I started to learn how to paint (in watercolours) - many people told me to buy Student Quality paint and brushes and someone told me to buy Artist Quality. I went for the cheaper option and boy, was that a mistake!! I made very little progress and was regularly frustrated. As soon as I switched to more professional materials, I progressed in leaps and bounds.

And so when it came to investing in a morse key, I was going to apply the same logic, but I really needed two keys - one for permanent home use and one that would live in my RuckShack for outdoor activities and for my stays at the caravan holiday home.

Until I knew for sure that I would be sticking with CW, I decided to buy an inexpensive key first. Nothing cheap and nasty, but nothing overboard either - something which is largely 3D Printed. I went for a CWMORSE  Dual Paddle and overall I’m quite happy with it, but if you read my review, you’ll soon realise that it’s not from the top shelf.

Later, when I realised that I was fully committed to the Morse Code journey, I considered the purchase of a higher quality key for home-use and it was on VE99K’s Blog that I found a likely candidate in the form of a Begali Key. I was already aware of this Italian manufacturer but had thought them to be out of my league until I read Mike’s blog-post and realised that their most basic iambic paddle key is pretty competitively priced and yet it still benefits from the Begali craftsmanship and quality materials.

In Europe the SIMPLEX BASIC costs around €130 but you can find them second hand for much less and there’s very little to go wrong with them. Of course even this, the cheapest of Begali keys, will be outside many people’s budget and there’s no doubt that you can ‘make do’ with almost any key, but I’m a big believer in investing in the best tools you can afford at the time.

When the Begali arrived and I opened the box, I was a little underwhelmed initially by the condition of the red paddles - only because one of them had some markings, probably from where they remove it from the mould. It was nothing major, but it just set me back a bit considering the manufacturer's reputation.

Anyway, the rest of the construction seems perfect and it all looks to be built to a very high standard. Inside the box you get a drink coaster(!), a QSL Card, a cleaning cloth and a Feeler-Gauge to set the gap in the contact points.

You also get a 3rd party 3.5mm stereo to stereo jack lead - I didn't use this - I fitted a 3.5mm female-socket instead, to enable me to use any lead I want with the key. You can see from the image above that you are required to solder a lead to the key yourself. To be honest, I'd have preferred Begali to have fitted a static 3.5mm socket to the base, but hey-ho.

With that little job done, I adjusted the points with the supplied feeler-gauge and then plugged the key into my little FX-4CR, set at 15wpm (the speed I'm currently learning at) and started tapping out my familiar CQ TEST CQ TEST M7MCQ string. To be 100% honest, I didn't feel that it was a whole lot better than my cheap CWMORSE key! 😮

Maybe my expectations were set too high because of the reputation of Begali. I adjusted the key some more, closing the points gap ever so slightly and that helped for sure, but it still didn't rock my world. 

I do have to bear in mind however that I am an out and out beginner at this, and I recognise that I may be able to detect some benefits later when I've spent a lot more time with CW. Perhaps it's like Hi-Fi, where the laws of diminishing returns kicks in - the more you spend, the smaller the improvements get.  I'm guessing that there are no night and day differences from one price range to another - it's all about subtle improvements.

I also note that the Begali's pivot point is different to the CWMORSE's. Could that make a difference to the feel of the keys? Maybe so. I increased the speed of the keyer to 20wpm and tried again. And that's when I detected that the Begali is probably easier to operate higher speeds. As daft as it sounds, I seemed to make less mistakes at higher speeds than at slower speeds with this key.

I should like to point out that despite the 1.4kg heft of the cast-iron base and rubber feet, the key moved around in my heavy hands, so I stood it on a non-slip mat from the £shop. 

I've used these particular mats before and know how incredibly well they work. They're very sticky - an odd material, but very effective. The only remaining movement is the flexing of the feet. 

Anti-Slip Mat

Ah well, it is what it is - "time will tell" as they say. I'll stick with the Begali and see how I feel in a few months time. It seems that keys are a very personal thing and what suits one person perfectly, might not suit another person at all. 

Again, I hold my hand up and admit to my lack of experience in this area. For those interested, here's what Begali say about their product...

The Simplex Basic may be our least expensive key, but it is a very capable CW instrument that can hold it’s own against many far more expensive keys on the market.  It is a iambic key with a heavy (1.4 kg or more than 3 pounds) cast base and gold plated components, using long springs for the return force. Like our other keys it is manufactured using NC machinery for absolute precision.  Micro-threaded screws are used for all adjustments.  

The arms are held by 4  ball bearings that are imbedded in the base, and they are made of a light-weight  alloy that provides very low moving mass - this allows excellent responsiveness at high speeds even when set for a very light touch. The contacts are 925/000 silver.  

The key comes with a protective dust cover.   The base of this key is made by melting and casting phosphatized iron. As a result, no two bases will be identical, even though the overall shape and dimensions are ensured by the mold. A rough uneven surface with individual patterns is characteristic for this process.  

With its uniquely shaped base and finger pieces this key is not only a precision instrument for the CW operator but also a piece of art that you can proudly display!

Thanks for visiting the blog.

LEARNING CW (MORSE CODE)

  MY CW JOURNEY (so far)  

Let's not pretend that this is anything more than a diary of a simpleton trying to learn a new language! I've just downloaded an app for my iPhone and iPad called MorseMania. It starts out free but you have to pay a small fee to fully open it up (which I did), but even the free version is a really useful start. 

I'm not expecting this to be an easy journey - in fact I think it's going to be pretty tough - I'm almost 65 and I've never considered myself good at learning new skills. People keep saying that if you have a musical talent, you will find CW more easy to grasp -  well I don't know a quaver from a crotchet, so there's no hope for me, lol. People also say you need good rhythm and timing - oh dear!

Anyway, I'm not trying to join the Royal Signals Corp - I just want to make some contacts on the CW portions of the bands. I want it for that reason and for the accomplishment - the challenge! I'm curious how far I'll get by the end of the year, not least because I've got 11 days off work over the Xmas period.

I've noticed that there are lots of people with lots of conflicting advice on how best to learn the code. Everyone has an opinion on the subject and some opinions are really quite strong. At the end of the day, you just have to go with what makes you comfortable I guess, because you know your strengths and weaknesses.

I've made my mind up that I intend to learn by listening to the sound of the characters if I can - this is quite a popular method anyway and not many people argue against it. There are a few letters however that just don't seem to stick with me, possibly because they're so similar to another letter, so for those I will use other techniques.

One thing's for sure! I will try to benefit from the time I spent learning how to paint and will use the same positive mantra to get through the tough parts...

• Practise often!
• Accept there will be lots of mistakes.
• Accept that you may progress slower than others.
• Don't try to over-achieve.
• Red wine helps everything (lol).
• End sessions on a high, never on a low.
• Don't tell yourself (or others) that it's impossible!
• Create and stick to a practise schedule.
• View it as a fun activity and enjoy it!

 

20th November 2023  DAY 1  

Day-1 saw me learning a few letters of the alphabet. MorseMania has a few set-lessons and they start with two letters - E & T. Simple! At the next level it adds A & N, then I & M, then S & O followed by D & U. 

Some letter are ridiculously easy to remember, like E, T, S and O and some others can be made to be easy by associating them with something - like "Dawg Did It" for D (-..).  Similarly, I used "The Dawg Did It" for the letter L  (.-..). For others, it seems that you've just got to muscle it. 

I was managing these 10 characters pretty easily and was impressed with myself, but as soon as I moved onto the next level (adding R&K) it all started to unravel. Grrrr! I couldn't understand how 10 letters felt so easy and adding just another couple had such a big impact. It was like I'd used up all my RAM and needed an upgrade. And this was just in the first 20 minutes!!

Obviously, I was expecting too much and that was my first real lesson - don't do too much, too quickly. Softly, softly, catchee monkey. So I went back to the start to get the first ten firmly in my head so that the introduction of an extra two wasn't such a burden on my little old brain. 

In-between MorseMedia sessions, I was using my Iambic Paddle to send a few strings of code. I learned to send "CQ TEST CQ TEST M7MCQ" for the purpose of seeing how far my signal reached via the RBN (Reverse Beacon Network).

Most people reckon that you shouldn't touch a key until you can receive CW at 8-12wpm. I can see the logic in that, but not everyone's the same and I didn't think that getting comfortable with the key would be a problem, but a trusted friend (G0VGS) explained that one needs to understand the cadence (the rhythm) of the letters before you can properly send them.

I thought about this and started to understand. We all know the unmistakable call of CQ in morse. It isn't just -.-.  --.-,  it has its own sound and shape!  So it was decided; I would keep away from the key until I had learned the characters and could reliably decode slow morse.

21 November 2023  DAY 2  

Another 20 minutes in the evening. Rather than move onto another level, I rather boringly repeated the efforts of the night before.  I felt that I needed more muscle memory. 

Had a coffee and then got up to Level 10 with no errors (fourteen letters including the R&K and C&P). Repeated this level over and over. I felt like carrying onto the next level but decided it was best to finish on a high.

22  November 2023  DAY 3  

Best to start each new session by repeating the previous level and making sure you can still do it error free. If I made any mistakes, I did the level again. Then onto Level 11, adding B&G.  Oh dear, this felt like a step up, but soon enough the new letters sank in. Up to this point I hadn't really used any techniques to recall letters, but for the letter B (-...) I decided to write it down on paper as shown below and that really helped me to get a grip of it.

Trying the same method for the letter G didn't really work out for me, so I just had to muscle it into memory. At this level I found that it was taking me longer to recognise some characters. I wasn't making any mistakes, but I was definitely slowing down.

23  November 2023  DAY 4  

I know this might sound a bit odd, but there are many occasions where I'm trying to study something in-depth and I suddenly feel very tired! It's weird, but it happens quite often and it's usually in the evening after I've finished work.

I guess it's my body's way of saying "Hey fella, give me a break"!  

And that's how I felt tonight after I'd had my evening meal and sat down to practise - I felt real sleepy, real quick! I don't think it helps having eaten quite a big meal either, so I've now adjusted my schedule so that I only start my practise session when I'm rested and wide awake.

So, after a short Nana-Nap 😂 I started work again and managed to complete Level 13 of MorseMania. Now up to 18 letters without errors - albeit quite slow again. Onwards and upwards! 

MY THOUGHTS SO FAR... 

So I've finished Day-4  and I'm thinking - Hey, you're doing pretty darned well.  I've gone from believing CW was an impossible dream, to being able to recognise 18 letters with just a couple of hours work!! 

Yes, I know there's a long, long way to go, but I am so pleased to have conquered that first barrier and reached the stage where I'm actually excited and looking forward to cracking off those last eight letters of the alphabet. 

At this rate I'll be selling my PreppComm MMX 😂

 

24  November 2023  DAY 5  

20 minutes of practise this morning saw me complete the whole alphabet - yes!! I'll be honest though - the full 26 letters has slowed me down somewhat. When I hear some characters I really have to think about it - and then I'm quite annoyed because it turns out to be a letter that I previously found very easy to identify! Grrr.

But, I'm happy that I've got this far with so little effort. I've decided that I'm not going to move onto numbers and punctuation yet - I'm going to stick to the 26 letters of the alphabet and focus on increasing my recognition speed and learning the sound instead of counting the dits/dahs.

A friend (Chris, G4HYG) told me about the CW WorldWide Contest running this weekend and recommended listening in to it, to see if I could pick up any of the code. It'll probably be too fast for me but I'll give it a go.

Speaking of speed, I chose to complete all the MorseMania exercises at 15wpm right from the start because there's something about very slow speed morse that just doesn't work for me. I think it's better to learn at a pace you hope to later work at.

I'll update this page when I have made significant improvement and moved onto the next stage.

WHICH QRP RADIO??

THINKING OF BUYING A QRP RADIO?

There's an absolute mountain of them out there and it's difficult for beginners to know which one would be best for them - there's so much to consider and a lot of it comes down to budget, portability, band coverage, feature set, preferred mode of operation and even aesthetics.

QRP is (loosely) determined as using up to 5W power output in CW mode and 10W in SSB. Anything above that isn't usually considered QRP, although people who regularly use 100W or more think of 20W as QRP (incorrectly in my opinion).

Some QRP radios are limited (or designed) to work in one particular mode such as Digital, while others will operate in every single mode available! The radios which are dedicated to a single mode, such as the QRP LABS QDX, will usually perform much better than those radios which try to do everything  (unless you pay a lot of money).

I've owned quite a few QRP radios and swapped and changed regularly over the last few years of being licensed. I've gone to a lot of effort in finding mint condition used radios at a low, low price so that I can sell them on without losing money (and sometimes even making money).  I would strongly advise others to follow a similar line instead of just forking out for new radios which will always lose a chunk of their value as soon as you open the box!  Having said that, if you absolutely know that the radio you're buying is going to be a keeper, then by all means search out a deal on a new one so that you benefit from dealer-support and warranty.

So let's look at some of the radios available. These are the ones that I have personally invested in and have used myself. There'll be lots of other radios that I've never had the opportunity to try and other people may advise you to look elsewhere for your QRP equipment. Just bear in mind that many people give advice without ever having owned something they're recommending - I don't do that.

The list...

• (tr)uSDX
• Elad FDM DUO
• Elecraft KX2
• Elecraft KX3
• Flex 1500
• FX-4CR
• Hermes Lite2
• Icom IC-705
• Preppcomm MMX
• QRP-LABS QDX
• QRP-LABS QMX
• Xiegu G90
• Xiegu X6100
• Yaesu FT-818

Somewhere on my blog there's a review of each radio, so I'm not going to go into great detail on this page - you can simply click on the blue-links to read the individual reviews after you've read this post. On here I'm going to give a very short summary and suggest why you might want to add it to your short-list.

(tr)uSDX              £110 New

I'll say straight away that I love this little value-for-money gem. I've actually got 3 of them 😮 and use them regularly. I have one at home, one at my holiday home and one in the glovebox of my truck. They are super compact and have a built-in speaker, built-in microphone, built-in keyer and even a CW decoder!! They have a tiny (but clear) OLED screen which on later models includes a bit of colour. The radio also has a great user-interface, making it easy to operate even for newcomers. It covers 5-bands and pushes out around 5W depending on band and power source (you can attach a regular psu/battery or power it up using a micro-usb lead and get around 500mW output (handy for extreme qrp experiments)). 

If you want to save more money, you have the option to purchase this radio as a self-assembly kit. Please be aware that there are some fake clones out there, so be sure to purchase only from an approved supplier. I will never forget the first day I received this radio - I unpacked it, connected my end-fed-half-wave and broke into a pileup, receiving a genuine 59 on the first attempt! Highly recommended for people wanting to "dip their toes" into the qrp waters.

 

Elad FDM DUO    £980 New

Considered by many to be the KING OF QRP! This Italian beauty has an excellent receiver which takes some beating, especially when used with the magnificent SW2 software - it truly is amazing!! On its own, the FDM DUO is a stand-alone HF/6M SDR transceiver capable of putting out up to 9W and needless to say, this is an all band, all mode radio. It is small enough to take out portable and substantial enough to be used in the shack as your main transceiver (especially if you opt to buy the matching 120W amplifier). When connected to a PC/Laptop (indoors or out), the radio is capable of providing you with 9 independent receivers with staggeringly good filters and noise blockers!! Yes, this is a hefty amount of money for a QRP rig, but it is that good. Highly recommended if you are quite technically minded and can afford it.

 

Elecraft KX2     £1000 New

This is an extremely popular 10W QRP transceiver and for good reasons. It is very similar in terms of performance to its big brother (the KX3) and yet it's much smaller and cheaper. Nevertheless, £1,000 is a serious amount of money and if you add the desirable options, that price will jump up closer to £1,600. This is a full blown SDR radio covering 80-10M, all-modes with superb performance and a built-in battery. These are much sought after radios and usually retain a lot of their original value. You could (if you want) connect it to an Elecraft amplifier to make it usable at home in the shack as your main radio. The Elecraft doesn't have any dedicated software like the Elad, so maybe not the radio for those looking to take full advantage of an SDR. Still, an excellent radio for POTA/SOTA.

 

Elecraft KX3    £1,500 New

The top of the line portable Elecraft. A superb performer with almost everything that an outdoor operator could wish for. 160-6M SDR, 15W output, all mode, with one of the best receivers on the market and a built-in battery. A superbly intuitive user interface and lots of optional extras available (taking the price close to £3000). The KX3 never felt rugged enough to me for regular outdoor work. Chucking it into a rucksack just never felt right - I was always guarding it. Back home though, you can connect it to one of Elecraft's excellent amplifiers if you have the license for it, but you do end up with quite a bunch of leads trailing all over the place. These radios have been easy to find on the secondhand market and prices fluctuate wildly. I bought one for £700 and sold it for £800. Then I bought another for £700 and sold it for £1700. Crazy! Like the KX2, there's no dedicated software available 😓. A lovely, lovely radio though.

 

FLEX 1500    £200  Used

The little Flex 1500 is not stand-alone, so you will always need to connect a computer in order to use it. If that's not a problem, then this is probably the most Value-For-Money SDR out there. You can pick them up for a couple of hundred quid and use them with the amazing POWER-SDR software by K9ENS. The radio will push out a clean 5W and covers 160-6M bands, all modes. The software is easy to use and incredibly comprehensive at the same time. To avoid any operational lag, you'll need a decent laptop, so you'll have to factor that cost in too. Obviously not as convenient as a stand-alone, but a great performer. Highly recommended!

 

FX-4CR.              £450 New

I have to say upfront - I'm a bit of a fanboy when it comes to this radio - I absolutely love it and even though I own some amazing radios, this is the one I probably use the most. It's not the best at any one thing in particular, but it somehow flicks all the right switches for me.

It's a high performance 10-Band SDR which fits in the palm of your hand. Its output can be adjusted from the mW range up to 20W and has a superb receiver, a full colour screen, a spectrum scope, a waterfall, built-in speaker (a good one) and even a built-in microphone. And all for £450 - not only that, it's also superbly built!! There's a real pride of ownership with this little gem and the designer (Yu Hongbo) is one of the most approachable and helpful guys out there. Now I understand that many people are very wary of buying  radios directly from China, but rest assured that you are safe as long as you purchase directly from his website.

 

I have used this little transceiver both outdoors and indoors and have been amazed at how well it performs. Regular firmware updates continue to make this radio better. If you want to invest in a mid-priced QRP SDR radio, then this is well worth considering. Highly recommended!

 

Hermes Lite 2   £250 New

I had heard lots of great things about this little DUC/DDC SDR radio and really wanted it to work out, but in the end it was too much of a technical challenge for me (I have very limited networking knowledge) and so I ended up selling it quickly (thankfully with no financial loss). The 5W transceiver covers 130kHz to 30MHz and has performance on par with radios costing twice the price.

The Lite 2 is not a stand-alone radio and is useless without a computer attached. Most buyers would be looking to leave it at home anyway and would access it from anywhere in the world which is a really attractive proposition, but to achieve that, you need to be quite techy (and have a license which permits remote operation). Although I'm computer literate, I have zero networking skills, so I struggled to do anything other than operate it directly.  Only consider the Lite 2 if you are very technically minded and a bit of an experimenter. Read the review and make your own mind up.

 

Icom IC-705   £1,350 New

If you want the most advanced QRP Shack-In-A-Box Transceiver in the world, then there's currently nowhere else to go other than an Icom shop. This technological marvel does it all! A Full-Colour Touchscreen, a Waterfall, a Bandscope, GPS, Bluetooth, HF, VHF, UHF, DSTAR, RTTY & PSK Decoder, AirBand, Broadcast Coverage (inc LW/MW), a Wireless LAN, MicroSD, QSO Recorder a built-in Li-ion battery and a Charger. Up to 10W output. Phew!!

This amazing transceiver has it all and can easily be used as your only radio (just buy an amplifier for use in the shack if you feel the need for more power).  There's virtually nothing to touch this radio at this price level and I'm just amazed that 4 years after it hit the shops, Yaesu still haven't responded to it by building something similar. HIGHLY RECOMMENDED for those looking to operate on HF/VHF/UHF with a single radio. 

 

PreppComm MMX £600 New

This one's a bit different in that it is a CW ONLY transceiver.  But it's much more than that! It's actually a QRP CW ENCODER/DECODER which means that you don't even need to know Morse Code 😮 How cool's that??

We all know that the most reliable (or effective) way to make DX contacts with QRP radios is in CW mode. Those dits and dahs just seem to penetrate all the noise and reach far flung places with relative ease. The MMX (a three band 5W radio) reliably decodes morse code and allows you to reply by simply typing a response on the supplied keyboard. It takes some time getting used to the vagaries of the MMX tuning, but once you've put some effort in, you will soon be able to rack up some previously unattainable contacts for your logbook. Read the full review before committing.

 

QRP LABS QDX £90 New

This is a DIGITAL ONLY 5-Band, 5 Watt Transceiver and it comes as a kit which may or may not challenge you depending on how comfortable you are with following instructions and soldering. Personally, I really enjoyed the challenge - so much in fact that I bought a second one! For an extra £45 you can have it pre-assembled. The performance of these transceivers is exceptionally good and I just can't recommend them highly enough.

There's another fabulous transceiver from QRP-LABS called the QMX and this one adds CW to the mix (and it's rumoured that it may be upgradable in the future to include SSB). 

 

Xiegu G90          £400 New

The G90 has an awful lot going for it, not least of all the fact that it is a 0.5-30MHz all mode SDR transceiver capable of outputting 20W! It has a small colour screen with panadapter and a great Icom-style DTMF microphone. It's not the most sensitive receiver in the world, but outdoors with a decent take-off, you'll be hard pushed to fault it. The only thing that I never liked was it's peculiar  size and shape. It kinda feels awkward. It offers superb value for money and works well with the Xiegu amplifier. Recommended!

 

Xiegu X6100       £585 New

This was a disappointing experience for me. I really wanted to like this radio but I ended up moving it on very quickly. It had quite a few bugs and some features just didn't work at all. Worst of all though were the number of birdies that were present right across the bands - some were ridiculous (IMHO). I'm aware that the X6100 has proven to be popular among many outdoor operators and on paper the radio looks amazing, but IRL it turned out to be disappointing. I'd recommend the G90 over it any time - especially because it's a lot cheaper and works perfectly.

 

Yaesu FT-818     £600 New

On sale for over 20 years, this little gem from Yaesu has been the go-to radio for outdoor QRP operators. Or it was until they ceased production earlier this year. As good as it was, no one could deny that it was getting a bit long in the tooth and was in need of a massive update.

Competition from Icom's (IC-705) knocked it into a cocked hat, and while the 705 costs over twice as much as an 818, it gave operators everything they could ever wish for (apart from an internal atu). I'm sat here with my fingers crossed that Yaesu will soon launch a modern replacement that will blow away anything currently available. But there's no sign of it at the time of writing.

Nevertheless, the FT-818ND is still a fabulous All-Band, All-Mode Shack-In-A-Box with a built-in battery and is an amazing secondhand investment. Just be aware though that the 817's can be up to 20yrs old and many owners expect silly amounts of money for them. If you can afford an 818, buy one. Read the article for more info.

And that's the end of the list. Thanks for reading my ramblings and I hope you've found something useful amongst it all. If you have any comments, leave them below and if you have any questions please feel free to email me m7mcqio83ro@gmail.com

YAESU FT-DX10 vs ICOM IC-7300

FT-DX10 REVIEW by VK4DX

I was reading a review of the Yaesu FT-DX10 Transceiver by Mike (VK4DX). It's an excellent and very honest review of the DX10 and he makes sensible comparisons between it and the IC-7300. Click on the image to read his review...

FX-4CR HEATSINK

There's been some discussion on various platforms suggesting concern over the FX-4CR's operating temperature, even though I've never heard of anyone suffering any sort of failure, so I do believe that these concerns might be a little irrational (but that statement might come back to bite me, lol).

Having said that, I've been guilty of similar worries with my Expert Electronics ColibriNano, which runs incredibly hot! I was so concerned that I wrote to EE seeking some reassurance and I was told very clearly that the unit is designed to cope with those sort of temperatures. Nevertheless, I decided for the sake of longevity, I would fit some heatsinks and after completing the task, I felt much better. The ColibriNano ran cooler to the touch.

So with that little success, I thought I'd do the same to my FX-4CR. Opening up the case, you can see that there's a large aluminium heatsink plate in the middle of the radio and the high-temperature components press directly against it to help dissipate the heat.

The hottest part of the radio is the very top (and slightly to the right side). This makes sense when you consider the location of the PA and so I decided to attach my heatsink there. It was a very simple matter to remove the top and rear covers, allowing me to apply a bead of thermal-paste to the internal heatsink. The parts circled in yellow are the areas requiring the most cooling.

With that job done, it was just a case of reassembling the radio and then applying the external finned heatsinks. I applied a couple of dabs of thermal-paste to the underside before spotting with high quality superglue, being careful not to get the glue on the rear edge (or I'd effectively be gluing on the rear cover, lol).

When the job was done, I ran the radio for 30 minutes or more, repeatedly sending a CW message into a dummy load at 20W. At the end of it, the radio felt pretty warm to the touch but there was nothing to worry about at all, so I'm 100% happy that there would be no issues with overheating at the power levels I normally work at.

I guess time will tell.

SPECIAL EVENT - BOTA 2023

My friend Phil (G7TVB) invited me to participate in the 2023 BUNKERS ON THE AIR event and although I had some personal issues which were causing a great distraction, I managed to activate two bunkers (ROC Posts B/G-0444 and B/G-0925) just before the time limit expired.

Royal Observer Corps monitoring posts are underground structures all over the United Kingdom and were constructed as a result of the Royal Observer Corps' nuclear reporting role - operated by volunteers during the Cold War.

These bunkers were manned by 3 or 4 people and were basically a rectangular space lined with up to 12” of concrete. This concrete box was approximately 14ft below ground level and had a large mound of compacted earth above its roof. A shaft with a ladder was the only way in and out of the bunker.

The estimated cost of each bunker in 1956 was £1000 and over 1,500 were needed to provide adequate monitoring across the country but as usual, costs escalated and prices rose to as high as £8000! 

The basic rules of the BOTA 2023 Special Event were that a bunker would be deemed ‘activated’ by making at least 25 logged contacts. Because many ROC Posts are on private land, activators were allowed to work as far away as 1km from the actual site.

The event ran throughout the month of October  and although it wasn’t a formal contest, points were available to activators, chasers and SWL’s in order to qualify for a Certificate (PDF).

Personally, I wasn’t interested in gathering points, but since my mate invited me to participate, I thought I should make the effort to activate at least one of the bunkers. G/B-0444 (FORTON) was not far from my holiday home in Scorton, so I chose to activate that one and used my Icom IC-705 with my AlexLoop.

The activation went well but driving winds and looming black clouds forced me to cut the activation short and so I had to return a few days later. This time I went out on my motorbike and used my new FX-4CR radio with a resonant dipole. It worked superbly and the activation was soon completed.

My second activation G/B-0925 (DUNSOP BRIDGE) was completed in a very short space of time thanks to great band conditions on 40M. Again I used my wonderful FX-4CR, but this time from the comfort of my truck, using a mobile whip on magmounts.

To be honest, I didn’t expect it to go as well as it did because of the antenna (Diamond HF40FXW).  I drove over to Dunsop via the gorgeous Trough Of Bowland and I enjoyed quite a few moments admiring the Autumnal views (despite the miserable weather).

Once I’d spotted myself on the BOTA group page, I very quickly got a little pileup going and before I knew it, the activation was complete! My thanks to all those who made contact with me - especially those who struggled to hear my QRP signal. The little FX was a joy to use and performed flawlessly.

On the way home back through The Trough, I took a few more photos…

Thank you for reading the post. I hope you enjoyed some of the pix of this lovely area.
