Anyone familiar with Q25, D22, D23 on the CTRL unit?
Mine got smoked by a close lightning strike.
I repaired it but its only partially fixed.
Apparently there are some shorted diodes on the RF-B unit.
History: The radio wouldn't make power, only a 50w carrier on all modes.
It did 100w with only 18db att. on oscillated at 0,6 and 12db, receive was 50% what it should be with 0 Att on the 24mhz up bands..
After fixing the CTRL unit, it would only make power in 6, 12 or 18db att. oscillated 50w on 0db.
Receive still low, nothing on the lower bands, no wwv, no broadcast stations at all, deaf.
Digging further I found shorted diodes on the RF-B unit. Mainly D104, D851 but others are leaky too.
(maybe just do them all?)
Anyone dealt with this before?
I've scoured the net I'm looking for some first hand knowledge.
Thanks.
