A while back I posted an inquiry regarding an R1225 repeater I was looking
at for another. it was deaf as a fence post.

 

Well, today I had a chance to finally open this thing up and get a look-see.
(This took so long because I've been "ridding myself" of a number of kidney
stones.)  Anyway, the front end of the receiver is burnt to a crisp - my
best guess is that it got hit with strong incoming RF that was not blocked
by a "mis-tuned" duplexer. or the owner hooked the duplexer up backward. (I
think this was discussed previously.)

 

Anyway, in order to get this thing going, I am in need of the receive board
layout diagram and a parts list.  With the radio oriented so the RX antenna
connection is at the lower left, the components that are toasted are just
"above" the antenna connection.  (They all look like SMC capacitors, but
without the board layout and parts list, I can't be certain - nor can I
determine proper replacement values.)  

 

If anyone can help, I'd be much obliged! 

 

Thanks in advance!
