Perhaps some have seen this on their TR-7;
average keydown power on all bands around 125 watts except on 10 meters where it
falls off to 90 watts. (using dummy load) Upon keydown and rotating the
carrier gain to maximum, the PS-7 trips and have to turn the radio off and back
on to reset the power supply. Could the overcurrent crowbar circuit in the
PS-7 be tripping due to the infamous PIN diode problem? Any input
appreciated,
Thanks,
