    Rest of the amp will consist of custom PIC controller with 20 x 4 display (same as beacon), LPFs, foward and reverse power detection and input attenuators.

    Thanks, no machine shop here, a shed and a jigsaw to cut the steel bits, a really cheap pillar drill and a £10 tap/die set from ebay. Copper was ordered as a piece which just happened to fit perfectly.

    the mrf150s i have are fakes, unfortunately. But after flattening the unbelievably wonky mounting tabs, they seem to work by some stroke of sheer luck. for how long though....

    Looks nicely done there :) Sorry you got some bunk components. Hopefully, real components wont throw anything off for you there on the final construction.

    Yeah annoying. Plan is to build all the monitoring and protection before ramping up the power. The MRF150s are 'remanufactured' (very poorly). I do not expect them to last long or work properly, but if I can get away with fakes, decent monitoring and careful abuse then that would be great
