CW filter / SSB mode / ICOM 746
- cheap solution
You can arrange the CW filtering
on SSB mode in IC-746 as "cheap solution". Use filter
350 Hz FL-232 and mark it in Item 4 setup as filter FL-223. For
Narrow band use filter combination 1,9 - 2,4 kHz, for Wide band 2,4
- 2,4 kHz. Set PBT as follows:
inner to middle position,
outer to 2 points right.
Center frequencies will be now:
LSB-N 980 Hz, USB-N 1980 Hz, Mark RTTY 1615 Hz, CW-N 500 Hz.
Results are on next pictures:
LSB-N (Hell)

USB-N (PSK31)

RTTY-N

CW-N

The bandwith and stopband are worse than for 3 CW filters solution.
