[MRCA] Test (and T-195 Autotune)

[aj1g at comcast.net]

Just trying to make a little traffic for Dale KW1I who has been having trouble seeing MRCA posts of late. Did you get this via MRCA Dale? 

Thanks to all who replied to my query on the lack of autotune on my T-195. I just printed off the operation theory for the autotune from the maintenence TM as well as the troubleshooting table later in the manual. I hope its not the chopper. If its one or more of the 1N67 discriminator diodes, is there something I can pick up from RS that will be functionally equivalent to the 1N67?. Last I looked, they did have something like the old 1N34s germanium dodes. I read on someone's post that matching a set of discriminator diodes for the T-195 application was not critical. 

FWIW, while reading the manual theory discussion, I realized that my tuning light apparently has never worked properly, and may be indicative that the autotune has been not operating normally for as long as I have had the set. My light comes ON when I hit the test key, and stays on after the tune cycle apparently was complete, based on a stable maximized output power.

Chris, 

I guess it's just quiet. All I've heard is crickets since I ask for walkie-talkie parts a couple of days ago.
