My vintage VHF rig is acting up after almost 30 years
of service. The 2-meter module is slow to produce
RF output when keyed. I suspect a sluggish oscillator.
The relays have been cleaned. Once it starts running,
the TX cycles are good, until the radio is left unused
for a period. Has anyone seen this before? Solutions?
I had it apart on the bench but could I was never
quick enough to catch the fault.
