[Icom] IC765 & filters

Sun, 24 Nov 2002 08:19:00 +0800

Hi Don,

The INRAD 455khz IF filter has better shape factor than FL44A.  In my IC756
(original version) filter upgrade, I use INRAD 109 instead of FL44A.  Result
is excellent and I have already said goodbye to the local big guns near my
QTH.  Adam, in his icom page, gives a lot of details of pairing of filters.
