[ICOM] HOW TO INSTALL FL-32A INTO IC-735???

[Gary Fiber]

GREAT !

I talked a number through this when I worked at Icom. Did one before my 
Icom years for a friend. I knew there were not to many cables that 
needed disconnecting but could not remember exactly which ones.

enjoy the filter it is pretty good.
