Excellent. We will soon be able to have entire QSOs and perhaps even

I'm sure Graham will provide a full answer, but I noticed this
in the "readme.txt" file (look in the Opera
folder):
v1.2.2 Beta
Mean Power and antenna data in Operator menu
Auto QSO option. This system send the QSO automatically when
the contact is done in both directions. One QSO every
24 hours.
I've not tried it and there is some discussion on the Opera
Yahoo pages about what constitutes a "QSO"!
Interesting thought about an ARQ type mode for LF. Pactor is a
proprietary mode and needs a licence from SCS-PTC.
For some reason, there are no currently available multimode programs giving
Amtor ARQ and it has dropped out of favour. However,
there are some recently developed (freeware) ARQ alternatives to Amtor (e.g.
V4Chat) and some that have adapted standard PSK modes
for QRQ but all are really intended for HF propagation conditions.
Of course Murray Greenman ZL2AFP has developed CMSK Narrow-band
weak signal mode for LF/MF QSOs, although it isn't
ARQ. I have been waiting to see someone trying it out on 136 kHz as it looks
quite promising.

Opera seems popular, are there any plans ahead for a basic QSO
mode instead of Beacon only.
At present on MF/LF it has popularity in its favour over the
other data modes.
Instead of FEC how about the amtor approach where the
transmission triggers a RX stn who responds and a QSO begins.
The exchange need only be a few key words.
How about modifying Amtor or Pactor for MF use.
