[Icom] IC-765

Sat, 01 Mar 2003 19:46:23 -0700

Hi,
The fan comes in two stages. The sensor is just sitting on the power FET 
with a dab of
soft glue. I use 765 daily. I guess PBT mod. is a must but it is so 
easy. Most time consuming was
PIN diode mod. and if you're CW man, the sidetone tracking mod. And AGC 
mod, Audio mod.
which needs only few mins. each.
73,
