Hi Paul. Idea number ???? If your amplifier is oscillating above MF, then you may be able to tame it by using a series capacitor and resistor between drain and gate. This will apply frequency dependent negative feedback which should stop the oscillation. (Not ideal as it shouldn't oscillate anyway...but a likely fix)Values are debatable, but 220R (1W) and 1000pF would be a place to start. 73 David On Sun, Jan 7, 2018 at 12:19 PM, N1BUG <[email protected]> wrote: Congratulations to 2E0ILY, G0LUJ, EB8ARZ/2, K3RWR, and WA3TTS/2 for the great trans-Atlantic work last night!
