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.
