[Elecraft] Fwd: RTTY split operation

[Jim McDonald]

I usually use two instances of MMTTY, one with the left channel connected to
the main receiver in the K3 and the other connected to the right channel for
the subreceiver.

More specifically, the first instance is run in DXLab Suite's WinWarbler.

By keeping the two audio streams separate you achieve the benefit of split
frequency pile-up operation.  The DX station is in its own decoding window,
and the callers are in the other one.  These days many stations continue to
call even if the DX station has come back to one station and even while the
DX station is still transmitting.

The P3 is a big help, but stations who call continuously make it tough.
It's also a problem, of course, if the callers are in your skip zone so you
can hear them or see them on the P3.

I think the K3's decoder is a neat feature, and I know many have used it
successfully.  In my opinion, it's not something I'd want to use in everyday
operation.  The same is true with sending RTTY with a CW paddle.

For lots of help getting started with RTTY, http://aa5au.com/rtty.html is a
standard reference.  The RTTY reflector is also very helpful:

I agree with Brian than recognizing 599 by ear is handy as is being able to
tune a RTTY signal by ear.

Another way with one TNC or instance of MMTTY.  Set L-MIX-R to Ab Ab. 
That way you get both channels out on one audio channel.  In practice that
works just fine for a couple reasons.

The DX isn't transmitting (though lids are) when tuning.
It's pretty hard to decode but the strongest pileup signals anyhow.

More reliable way of finding who is being worked is being able to decode
599 in your head.  It is far more reliable than hoping for any program to
decode a pileup.

Works for me.

CW mode, to see the rare station working split and simultaneously find in
pileup the answering station? For example to leave the internal  decoder on
the RX screen for channel A to see DX stn and channel B to be feeded for
decoding program in PC (to find pileup).
