In some YouTube videos I’ve seen people put 3300uf electrolytics in cobra 29’s and similar radios, on the dc power jack... but on the rest of your questions i can’t help you.

I’m still grasping at how all this stuff works, and how all the parts work together. I did make a small discovery. On pin 1 ic3 I have 17.755mhz on pin4 10.240mhz and on pin 8 27.255. I’m still struggling on tracing the signal. I feel like it’s close to working though... if only I actually knew...

I think that’s partly or entirely what is wrong with this radio. I’m afraid somebody has messed with the tuning cans in this radio. I got clear receive for the first time ever about 30 minutes ago by tweaking l19 and l18... before that receive was totally garbled. Now I’m able to hear locals...
