[Icom] IC765 & filters

Sat, 23 Nov 2002 13:43:38 -0600

Hi Group,

What if any, is the Inrad filter equivalent to the Icom FL-80 filter, any
advantage or disadvantage to
the Inrad filters.  Have an Icom 765 that I would like to replace the stock
filters in. Or would
like to purchase the FL-44A and FL-80 if there might be any for sale.

Thanks

Don    w0dg

Hi Isaac,

No, you cannot select a CW filter in SSB mode. You will need to use the FSK
mode to select the 500 Hz filters.

Cheers for now, 73,

Hi Adam
Thanks again for clarifying this.
I stumbled into another issue - maybe you'd know:
When I do RTTY via AFSK (SSB mode) , can I still (in some way) select a
narrow CW  filter for it?
(If not than I must use the radio's FSK I guess).
