Writelog supports having 2 instances of MMTTY,  one decoding the main rx
audio and one decoding the subrx audio. It has 2 frequency entry windows one
for each rx so you can log the qso on the correct frquency.

I got to use it in CQWW RTTY and it was very useful function

The best way to handle RTTY with signals on both receivers is to run
two copies of MMTTY (or other decoder) - one for reach receiver.  MixW
has a dual receive capability - I don't know about any of the other
software.  In general, one decoder uses the soundcard left channel
and the second uses soundcard right channel audio.  Mixing the two
audio streams does not work ... it merely results in QRM.
