I have an RV75 synthesized VFO that has suddenly stopped tuning up in
frequency. No matter which way you turn the knob, the receiver tunes down in
frequency.
The problem appears to be in the optical switches on the encoder shaft, as
voltage measurements indicate that one of the photo-transistors is not turning
on when it should.
Does anyone out there have replacements for these optical switches
(OPB813S-10)? Searching on-line indicates that a parts source might have them,
but they seem to have a very high minimum order (but still less than the price
of the RV75!).
Many thanks!
