COLIBRINANO by EXPERT ELECTRONICS
Some time ago I had an Expert Electronics MB1 and it was fabulous. I especially loved the software. But the radio broke and so it went back and was replaced with something else.I miss the ExpertSDR software very much - it was really very good and so I was looking into ways of getting access to it without spending thousands on another EE radio. They do manufacture a number of options but the only one that is reasonably priced is the one that look like a cheap USB Dongle! Except it's not cheap.
£250 seems like an awful lot of money for a USB receiver, but then again, you can pay much more than that for an ancient secondhand superhet receiver. This baby is brimming with SDR loveliness and high-tech wonders. And then there's the brilliant software. And then there's the REMOTE OPERATION capabilities!
Well the usual thrill of unboxing your latest toy and sifting through all the manuals, cables, bits and bobs is not what you're going to get here. It's a bit of an anti-climax - especially for a £250 product 😂.....
The Nano has a clock-rate of 122.88MHz and nine IQ Sample Rates ranging from 48kHz right up to 3MHz. Choosing the right rate can provide you with the perfect frequency span on your bandscope. Frequency stability is quoted as +/-0.5ppm which is pretty good considering that the aluminium USB body temperature can change from very cold on startup, to really hot during extended use! The USB connector is Type-A and is USB-2. Although the device is very sturdy, I would not like to leave it hanging out of a laptop connector, preferring instead to connect via a short USB lead. I also connect the antenna to the Nano with a short SMA~SO239 pigtail.
There's a different version of ExpertSDR for each of the radios that EE sell and obviously, some have more options available according to the radio's feature set. There's no point for example, having a wide range of TX options on display for a receive-only unit like the Nano.
UPDATE : EXPERTSDR3
I installed ESDR3 and it worked superbly. I managed to get it synced with my Kenwood TS-5900SG too, using OmniRig. ESDR3 is far more CPU-Efficient than V2. Just need to configure it to suit my personal and operating tastes. And then learn how to configure Remote Operation.
