Few weeks ago I have decided to resume building my mcHF kit. I have made good progress with the RF board and today I have tested the low-pass and band-pass filters.
SDR
My mcHF UI board is alive!
After completing the UI board I really wanted to see it work and test it one way or other without the RF board.
mcHF build status 2014.07.19
Last night I mounted the LEDs, the electrolytic capacitors and the LCD panel. I am using the HY28B which is why the display doesn’t align with the push buttons.

I forgot to post this update but I did make some progress since the last report in June. Finished mounting all connectors, buttons and encoders, see photos below.
mcHF build status 2014.06.23
Last night I finished mounting all the small parts on the UI board and today the board got cleaned of extra flux (there was a lot).
Ready to build
All parts have now arrived and I am soooo ready to build my mcHF
Software Defined Radio the way it should be
I have been looking into various options for building my own radios again, this time taking advantage of software defined radio technologies. I’m not crazy about using a PC for running the SDR application. While a PC offers great performance and flexibility, it makes a clumsy radio setup not at all suitable for portable and mobile use.
Cubieboard as Funcube-1 telemetry receiver
Following up on my not too successful first contact with the Cubieboard, I have decided to try it one more time. It has been annoying me to have a computer board lying on the shelf not doing anything and since I wanted to migrate my Linux-based Funcube telemetry decoder from a PC to a single board computer this was an excellent opportunity / excuse to try the Cubieboard again.
Updated fcdctl for the Funcube Dongle Pro and Pro+
About a year ago I wrote about my modified fcdcontrol application that could be used with the Funcube Dongle Pro and Pro+. The news back then was that it could be used on the Raspberry Pi to control the FCD instead of the continuously failing attempts at running qthid. Unfortunately, the fcdcontrol application often crashed due to a problem at the hidapi / libusb layer.
A 2-channel AIS receiver using rtl-sdr and gnuais
For some time now I have been in great need of small and cheap AIS receivers that could be used for guiding various tracking equipment during Copenhagen Suborbitals missions. AIS stands for Automatic Identification System and is used by maritime vessels for reporting various status, including position, heading and speed.
