The PL680 is much smaller and it's a good radio, but the fact is, I fancied something with a bigger speaker - nothing huge, but something which had clearly better audio and give me a more comfortable listening experience - especially on FM and SSB.
The new 501X from Tecsun is bigger than the 680, but it's a step too far in terms of size and price, so that was out of the question. Somewhere in-between is the PL990X and that's the one I decided to buy.
The 990X is the replacement for the well established (and well liked) PL880. I was actually considering a used 880 but I always feel drawn towards the latest designs which usually have more features and have the bugs of the previous model ironed out.
Needless to say, I did not want to pay the full retail price of the radio, so I had to be patient and use my usual techniques to find a bargain. In the meantime, I advertised my PL680 and got the most I could for it using a great advert. In the end, it cost me £85 to swap.
When the PL990X arrived in the post, the opening of the package was a very pleasing experience - the presentation of the product is first class as usual. The radio comes in an attractive box and contains a nice faux leather case (as did the PL680) and a useful retractable wire antenna. There was also the world call-sign map and fold-out guide. It's a really nice little package and you get the feeling that Tecsun haven't skimped on anything.
The radio is powered by a (supplied) single 18650 3.7V Lithium Ion rechargeable battery which is unbranded, but lasts a decent amount of time and the battery-indicator seems to be usefully accurate. I already own some high quality, high capacity 18650 batteries, so I'll switch to them to improve battery-life further still.
Handling the PL990X for the first time gave me the impression that it's quite a beefy radio, but it's only because I'm so used to handling the smaller 680. After a while, I was happy that it was 'just right' (sounds like the Three Bears story) and this would definitely be my go to radio for general SW listening.
The quality of build is typically 'Tecsun'. I really do favour this brand and have never been disappointed with their products. The plastics and general fit and finish has always been of a good standard and the controls always seem to feel smooth and yet rugged - sometimes more so than on some other more expensive radios from the big name manufacturers!
The antenna feels smooth and well made, but I really do wish that manufacturers would consider fitting a BNC connector to their larger radios - that way we could quickly and easily try out different length telescopics. Speaking of antennas, they include a wire antenna on a retractable spool and whenever you're using an external antenna, you get the (important) option of being able to bypass the internal antennas (ferrite and telescopic) by flicking a switch on the front fascia. Another switch below that, adjusts the front-end gain.
One of the best things about the PL880 when it was introduced back in 2013 was the radio's audio quality and I'm pleased to say that its successor has carried that forward. The sound from the single speaker is really pretty good at normal volume levels.
Broadcast stations on FM sound fabulous and connecting a decent pair of stereo headphones makes it an even better experience. SSB signals sound great too. Like other compact radios, things can head South if you crank up the volume too far, but in the main, it's very pleasing. Some claim that the 880 has a slightly better sounding speaker and that might well be true, but the fact is, it's discontinued model and the newer features and improvements of the 990 more than compensate.
Unlike the PL680 the 990 has no AirBand coverage, which is a great pity. To be fair, I tend to use dedicated AirBand radios with fast scanning abilities but it's always nice to have the option of tuning to a single frequency such as your local Tower and listen in while doing something else.
The 990 benefits from having switchable LSB/USB and I have to say that the audio is far better than on the PL680. I was particularly impressed by this and was reassured that I'd made the right decision upgrading. Another big difference between my 680 and the 990 is how the 680 is very sensitive to touch - having your hand too close to it altered the signal strength, which was annoying. Thankfully, the 990 is fine when being handled.
Synchronous Detection is available and I found that it works fairly well but does introduce some unwanted filtering of the audio on certain frequencies. From what I've read though, this is infinitely better than the 880 (so the 880 must be real bad).
When listening to the ham bands on SSB (something I do a lot), the AGC seems a little slow to react, but I have to remember that I'm subconsciously comparing it to my (costly) ham radios, which is kinda unfair. I guess I'm being a little picky about it.
Tuning around on the 990 is a very pleasant experience. I love the knurled tuning dial and the equally useful fine-tuning dial. On the top of the dials there's a friction pad to make it easier to turn them with your fingertip. Direct-Input of frequencies is simple, making well known stations easy to tune into. Needless to say, the radio has a massive memory bank with useful 'Pages' for grouping. With the rear stand flipped out, this radio is supremely comfortable to use as a desktop radio.
Using the built-in telescopic antenna, the sensitivity of the radio is really quite good and I did a few side-by-side comparisons with other radios including my Belka DX (a miniature marvel which positively shines on its (BNC) telescopic) and my IC-705. They compared favourably and the same could be said when connecting an outdoor antenna.
With the 990 connected to an outdoor EFHW, stations from much further afield could be pulled in, but it's important (IMHO) to use a coupler or manual atu in order to get the best out of the antenna. You don't have to buy something expensive - you can use something cheap from a radio-rally or buy a Kanga kit or maybe use a ZM2 if you have one. But use something!
Other features of the PL990X include an SDCARD slot which can be used to store MP3s for replay through the radio's speaker. There's even a useful bank of control buttons for Play, Pause, Stop, etc. Sadly, you cannot use the card for recording signals from the radio (probably due to some copyright laws). Initially, I didn’t think I’d use the MP3 player much, but I actually use it quite often and I love how you can use the Main Dial to move through tracks and the sub dial to move through albums.
Another useful feature is the built-in Bluetooth. This allows you to connect the radio wirelessly to something like your iPhone which is great if you want to play music, podcasts, etc.
On the left side of the radio there are sockets for external antenna, line-out, headphones and a USB port for charging (charger is included). The USB port can also be connected to a PC to play computer audio, but I can't imagine many people will. On the other side is a slider to alter the audio tone. On top of the radio is the option to put the radio in snooze-mode, adjust the display or lock the radio.
CONCLUSION. This brief look at the PL990X, leaves me thinking that it's a real nice bit of kit which works extremely well, is fully featured and has a lovely sound in all modes of operation. Even CW sounds nice and crisp with the 500Hz filter engaged.

| Guzheng/Guqin |
There’s something quite magical about sitting on the sofa, radio in hand, tuning through the bands and virtually travelling across the globe, listening to different music, languages and viewpoints. I can never quite explain to people why I’m able to enjoy listening to some pretty esoteric music, such as a Guzheng player in a studio 6,000 miles away! I think it’s something to do with my experiences as a youngster with my little 6-Transistor radio.
It's a nicely sized package (as the actress said to the bishop) and is super easy to use on a desktop or in your hands. I’m absolutely over the moon with this radio ands would strongly recommend it. The biggest drawback is the (UK) price of £269 at the time of writing. I think it cost far less at the time of launch, but prices of electronic goods have rocketed over the last couple of years. If you're willing to chance purchasing directly from a China based store, then you can drop that price significantly. Or alternatively, buy second-hand.
