ICOM new model IC-756PRO supports PSK31 mode.
It has 50Hz IF-DSP filter.

Can you or anyone else provide me with similar instructions for using this
technique on an ICOM IC-746? It would be greatly appreciated!

Hi all,
Was on 15 this afternoon and wkd DL8WQ and
XE1JP. XE1JP (George) is usually on around
22:00 on 15 looking for some DX or any contacts.
I just went down there and made some noise.
Signals were 599+. (Just thought I'd mention that)
Well, I think I'll go up on 40 mtrs to see if I can
scare up some contacts. I'll be on 7070, give or
take the qrm.
It's 0000z, so I think I'll go up there for an hour or
so and make some noise. Anyone want to join me?
See ya there.....
73,
John K1RC (ex K1CGJ)
