    Hi Peter: Another excellent repair, Sinad meters are still available in both kit and built versions at a pretty reasonable price. Andy

    This repair actually looked easier than it really was. Because of the FET short gate to source, we had a lot of impedance mismatch. This makes it difficult for you to interpret the measurement results... On video, you saw the short version :-)

    Excellent as always, thank you….one question : the fact that only VHF was affected by the Fet failure means that UhF and 1200 were using different Fets ? Being certified up to 2/2.5 GHz I thought that all three band were using the same amplifier section…

    IC-9100 doesn't have pre amps for 2M, 70cm & 23cm so it should be a bit deaf.

    not having a pre amp does not automatically mean the radio is a bit deaf.
