ok. I'm beginning to think that this radio is possessed..lol

So I go back into the shop to check out what you asked about measuring both sides of C163. I plug the radio in and turn it on. When I keyed it up, it dead keyed at 8w and was stable. I tried it both on ch1 and ch40 and 8w and stable. IC5 (the mixer) was working properly when I was troubleshooting the radio the other day but I thought I would check it out again. These are DMM voltage readings of IC5 as found a few minutes ago.

pin 2  .469v rx  7.93v tx

pin 3  ,469v rx  7.93v tx

pin 5  .469v rx  7.93v tx

pin 7  .469v rx  2.85v tx

pin 8  .469v rx  2.85v tx

pin 11  1.41v tx

pin 13  1.41v tx


ok..so then I measured both sides of C163 with the RF probe

closest side to IC5 read 2.270v tx

other side was 3.5v tx

at this moment in time it appears that this thing is working. I will try it again in the morning to see if it still works....it's been a long day. Thank you so much for your help in the matter,sp5it. I really appreciate it man. I will post an update in the morning time.
