Hello All,
Patrick is to be commended on his efforts to date with regard to
adding ALE capabilities to MultiPSK in support of Amateur Radio
application single channel.
I have been using his new a bit for the past two days and I find his
new ARQ FAE protocol which is based on the DTM ARQ and DBM ARQ
protocols of ALE with his modifications and influence of PAX. Its
bi-directional as is DBM ARQ and its much faster than DBM ARQ and
offered in two frame selections, 30 and 63 characters.
The ALE support provided to date in MultiPSK is limited with regard
to full ALE operation, it will decode a number of ALE data
transmissions, it fully supports an ALE linking call being made or
received and it will display and AMD as well as send an AMD at ALE
link. I have not learned how to send an AMD other than during the ALE
linking call if supported. I have not learned how to send and DTM or
DBM based messages eitther, if supported. It will decode for display
DTM and DBM traffic however there are issues with support at this time.
The real thing of interest however is the ARQ FAE protocol that
Patrick has developed, as stated, its a hybrid protocol that is a
full ARQ and based on the ALE standards as is GTOR and is very fast
compared to either. It has great potential. I have used is keyboard
to keyboard and tested the bi-directional aspect here, that was
challenging, luckily I can type on two keyboards with both hands at
the same time but its sending the characters as typed and not on the
enter keystroke, thus the challenge, I have also sent using ARQ FAE
from a text file, I have not learned how to cut and paste into
MultiPSK if supported, to send a message.
DBM ARQ is a very robust FSK protocol, its deeply interleaved and
resists QRM, QSB and fading, in my opinion its better than GTOR, the
tweaks that Patrick has made with ARQ FAE are my opinion a wonderful
step toward an excellent new Amateur Radio PC Sound Device Modem
based ARQ protocol based on the best of DBM ARQ and PAX.

Hello to all,
As said by Bonnie, Multipsk proposes now some basic ALE functions,
but not in the official version (which is still 4.1.2). For
instance, it is only under a test version.
For the Hams interested by testing ALE, Unproto or ARQ FAE, here is
the original test message.
