    Quick update. Reseating the ribbon cable between the RF board and the top board has fixed the Keying problem, however I still have no power to speak of

    Did you make a note of the settings in the main menu first. Some of the values may be incorrect.

    I'll admit I didnt, however I expect that these have just factory defaulted anyway as the CMOS backup battery was flat. I have replaced it and it now remembers settings. AFAIK they are required to align the radio in relation to the filters and such, rather than the old trimmer to tweak the crystal oscillator.

    So I am still getting RF output, that I can hear on another receiver, and its roughly on frequency, but no power.
    When I get a moment, I will pull it all down, pop off the amp shielding, and check the output FETs

    Neither of my local suppliers, WES and Element 14 / Farnell stock the devices, but there are plenty listed on eBay. How many are genuine, and how many are "Fake News" is yet to be determined.

    Element 14 however, has a whole selection of RF MOSFETs from a few watts to a few KW. Once I pop the covers off, I'll start looking around
