Nothing at all Don, I found that on my TS-850S that I could not used the 400hz
filter on LSB with the PSK tone at 1000hz. At 1800HZ, I could now use the
filter after moving the BPF. I used 1800HZ for a long time until someone
suggested 2125. That worked too, and easier for these old RTTY ears to
pickout. PSK doesn't care, just pick a freq that will work with the rig your
using.

Please an explanation why 2125 is a good place to have the center
frequency. I use 1 khz, I trim the SSB filters down to 400 hz in the TS870
(I've tried to use the PSK filters @ 300 hz, but I think the SSB filters @
400 hz seem to work better for some reason). I use my NIR-12 audio
filter in the CW position and all works very well.
What are the advantages of using 2125 other than it sounds better to
the RTTY trained ear?
Thanks,
