[Icom] Article on improving IC-765 AGC/Audio

Thu, 4 Apr 2002 13:16:29 +0600

I did not do AGC mod. Just like it as it is. But I have PBT mod and CW
tracking mod. Both are very useful. I use IC765 in every contest. Superb
radio. Having 3 high power stations in the vicinity of a few hundred meters
from me in every contest calls for a very good radio with high dynamic range
and tight filters. IC765 meets all these requirements.
