What is the voltage on P11 of the channel selector U1000?
Does it vary with the tuning?

Seems it does not. Have to messure this one.

Very often the channel selector has to be replaced
UV816 4822 210 10365

That's really bad news. uv816 is the one.
Better I go find a replacement The picture was exellent.

I think You'r right. Thanks!
