That is good information. Mine has never had good side tone, and cannot feed through the ID tone from my KN53. It works, though, and won't get replaced until it dies or the channel spacing gets divided again. I love its memory circuits.
The little neon tubes have never given me problems - as I understand it, they routinely die on King stuff.
I have an SL-40 in the Cub, and absolutely hate the memory circuits.
Thanks for the effort anyway Web.

....Hotrod. If you are not using an audio panel, you need to spoof the side tone for this radio. There should be a jumper between pin 6 and pin J. If it's not there you won't have side tone at all. Web
No audio panel. I recall looking for a sidetone adjustment screw on the top / bottom of the radio but no joy, so the jumper between 6 & J is probably the only solution. At first the lack of sidetone really bothered me, but after a year & a half I'm used to it, so I don't plan on messing with it if it involves more than just turning a screw.
Re memory, the Com 810 doesn't have one. Defaults to 121.5 & 122.7 (or 122.9?) if the radio is turned off. Again, at first this really bothered me but now I'm used to it. It requires you to think about what freq you need, so if you want to look on the bright side you could say it's a feature, not a problem.
Similar question...I just paid someone way too much to rewire my NAT intercom and Garmin 250XL. (had to move headset jacks to wing root panel) Now I have no sidetone and had to turn the NAT audio receive level way down to eliminate radio noise. Could this be caused by the mic switch ground being routed to the ground block instead of the radio?
NAT 85 set up at a NAT 80-01 with just two positions. My mic switches are in the throttles, one lead to the mic tip on the jack and the other to a ground block. F-4Gs...God's proof that given big enough engines even a brick can fly. Great plane, great mission.
Good on you. Did you get the magic blue retirement card?
I'm using the same intercom and radio that worked before...fabricated new harnesses and rewired the NAT and Garmin pin connectors. I used a shoulder washer and phenolic washer to isolate all four jacks, Did not wire music or emergency jacks. The configuration dip switches are correct for a AA80-001. (they were not before the rewire job???) I'll go back and study the wiring diagrams, I read something about this problem usually caused by multiple grounds.
