Interesting observation while trying to work FT4JA on 30 meter RTTY last
night. Using Windows 7 Pro 64 bit, I had been trying to find a stereo
mixer program that would allow 2 versions of MMTTY to run, one connected
to the left channel for the main RX and one to the right channel for the
sub RX via the K3S USB connection with the K3S in SPLIT.
Last night, I accidentally discovered that both channels were showing up
on ONE version of MMTTY running. I could set the main RX on the DX
station's frequency, lock it so it wouldn't move if bumped and whenever
FT4JA would transmit, I'd get mostly decent copy of what he was sending.
I could also, by judicious manipulation of VFO B, tune across the
pileup and also decode the stations there. I couldn't isolate one
channel from the other but they both decoded in MMTTY. Not sure how
that's happening, but it's an interim solution to the situation anyway.
Since I was seeing both decoded, I ran another instance of MMTTY, and
let it decode both as well.. That way there didn't appear to be a
conflict seeing the FT4 when he transmitted at the same time as one or
more stations in the pileup.
Didn't manage to work him, but at least I could see both ends of the
QSO's. Now I hope they run some more RTTY on a band I can hear them on
- LOL.
