Hi Everyone,

?

I am currently restoring a 1st generation ft-101 (actually a ft-277...) and while smoke-testing it I found that the RF board may need to be repaired or replaced; Therefore, I have two questions:?
- Does anybody have a drawing of the PB-1077B board with the parts indicated? (the yaesu manual shows just a few of them)
- Apparently the PB-1183 board can also work in an old ft-101, and it can still be found; has anybody tried the replacement?

Any help or advice will be appreciated!
Best Regards, and Season's greetings to all

Hello Joseph,

?

I have replaced the PB-1077B on my FT-277 with the later PB-1181. You may need to perform a realignment of the radio afterwards.

?

I have placed a file into the Files section, of the PB-1077B info that might help.
