Expert Electronics ColibriNANO SDR

I’ve been playing with a lot of SDR dongles this weekend, had the ColibriNANO on the go on Sunday.

ExpertElectronics say:

the The ColibriNANO opens new horizons for HF band enthusiasts, thanks to its 14-bit ADC, which provides a ~110 dB BDR and up to 3 MHz sample rate. A 0.5 ppm local oscillator gives the ColibriNANO a great frequency stability. Using the ColibriNANO remotely, in some rural area will give you the lowest air noise you’ve ever seen while won’t rob you from any comfort or functionality. The ColibriNANO operated by our own ExpertSDR2 software and compatible with popular HAM software such as HDSDR, SDRSharp via the ExtIO library.


Typical Applications

  • Direct connection with your laptop
  • Remote operation
  • Remote connection with a local transceiver

Remote operation with the ColibriNANO receiver

To control the ColibriNANO via Internet we created the ExpertRemote system, based on the client-server connection. This system allows you to place the receiver and server in the remote location with low air noise and Internet connection. This might be some remote village or place with no electrical interference and 3G/4G Internet (or any other connection type). Using the ExpertRemote system you can enjoy clear air from your phone, tablet, notebook or PC. Even simple antennas, placed in a “quiet” place, allows you to listen to the far stations with low level.
Another feature of this system is that the receiver’s software can be synchronized with transceivers and be used as the panorama adapter with high resolution. Use the transceiver to transmit signals, receive on your remotely located receiver via the ExpertRemote system.

Distant stations, rare (DX) stations or expeditions from now on will be a reality for you with our ExpertRemote system!

More information about the ExpertRemote system you can find here.

The New Flex 6400M

The new Flex range is superb, I have been using the new 6400M today, stunning bit of kit, really smooth..

the screen is clear and uncluttered, the windows 10 based app is just superb, well written and again really slick..

The latest version of smartSDR is much improved, with the colours leaping off the screen, clear crisp performance just brilliant..

There’s a book all about SDR “software defined Radio” get it here: 






As always have fun! Gaz

Raspberry pi 4?

Ooohh it’s February, remember February 2016? Well the raspberry pi 3 was released.. I wonder if the the pi 4 will make an appearance this year? Or maybe we will have to wait till 2019 🙁

The pi 3 made micro computers almost a daily driver, but it lacks a little horse power, imagine 4 GB ram on a 1.8ghz CPU running some whizzy edition of Linux.. sporting usb3.x 🙂

Keep the raspberry flag flying, I was late to the party but have to say the pi 3 has a place on my lab bench 🙂
