Just Google it, there are plenty of hacks there.
Old IC-735's are loaded with problems. Good luck.
if you would care to elaborate?
I am trying to keep it around $250 do you have any other options?
I am all so looking at a
RCI-2990
KENWOOD TS-430S
Go with the RCI-2990 for 11 meters. The old 735's have cap deterioration issues, they drift and I could go on. I won't tell the whole story but one month a few years ago I went through 3 of them and all were pretty bad even though they looked great. Heck they're 30 year old radios just like the Kenwood 430S which also had soldering QC issues from the factory. Especially on the PA board. I re-worked one of those as well...no fun.
I got a RCI-2990 came with a D104 it was a little more then I wanted. But ill be happy with it.
