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

[Ed - K9EW]

Thanks Gary,

The operation was a success.  Strange I couldn't find any documentation on
the Internet.

The only problem I had was coaxing the Main Board to slide forward enough
to clear the rear lip.  I unplugged the small coax cables and two 3-pin
connectors, labeling each one according to its Jack number on the board.  I
put a drop of DeOxit on each coax pin when I reinserted them - just to
avoid future problems.

The filter works great, and now its installation is documented.  The IC-735
is an older radio, but it's very easy to use.  It's a good starter radio
for HF.

Thanks for taking the time to write out the instructions.

73,
