What is the proper procedure for adjusting the controls of the GØMRF 300
watts LF amplifier VSWR protection circuit? I recently had a FET to
fail due to the antenna going off resonance when the loading coil
windings received a coat of ice. I had the protection circuit working
initially by detuning the antenna and trial and error tweaking the
controls. The circuit failed to work because of a poor ground
connection at a plated through hole on the control IC. I now seem to
have the amp and protection circuit working again but this time would
like to adjust the circuit properly.
Thanks,
