[WriteLog] AFSK on RTTY not LSB on 1000mp field

[Bob Naumann - N5NJ]

The dual peak filter is nice in the rtty mode, but I don't think you give up anything related to the filtering in rtty mode - do you?

Since it's all DSP anyway, can't we manipulate them in rtty mode pretty much the same way as in LSB-D?

I have never explored the use of the LSB-D mode on my 756PRO because I fell 
in love with the TPF RTTY filters. I liked the TPF RTTY performance so much 
I bought another 756PRO for the SO2R setup.

How do you use LSB-D in a way that is superior to ICOM's high tones TPF? Is 
your preference based on filter performance only, or do you need the low 
tones setup?
