[Icom] IC751A & filters

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).
