My son (ON3II) and I just started building the mcHF SDR Transceiver project form m0nka (http://www.m0nka.co.uk).
It is an interesting project and honestly quite difficult to complete even using the pre-populated boards.
There are so tiny components such as the coils and some SMD integrated circuit which are requiring a proper SMD soldering station. A reworking station might do the job but the risk of de-soldering another component installed nearby is very high.
The radio itself costs 259 GBP plus 10 GBP for the shipping in Europe which converts to 350 Euro circa, not a bargain but still a funny project. The kit doesn’t include the box neither the Power Amplifier final Mosfet (RD16HHF1); the box is available from Artur SP3OSJ (http://www.sp3osj.pl) for 50.50 Euro shipping included in Europe. For the Power Amplifier MosFet, you can find them almost everywhere at a price ranging from 1.50 Euro to 25 Euro per piece. I bought mine from FunkAmateur in Germany (http://www.box73.de) for 6.70 Euro each, so 13,40 for the pair plus shipping.
I’ll post a review as soon as the kit is completed.
