It seems like there are a rather large number of frequencies on each
band for this mode. I could see perhaps one watering hole for ALE,
particularly since it is such a wide band mode. One ALE signal will take
up as much as all the PSK31 signals on a given band and probably even
more than that
Hi Rick,
There is presently an appropriate number of frequencies for ALE in the
international channel list. We originally started with more channels,
and for a while we tried using less channels. Now it is just right for
the present situation. Keep in mind that the frequencies are
coordinated

Hello to all,
I plan to make some test with JNOS or other derivatives and wonder what
versions of *NOS might be ok for my old 80286 PC AT (12 MHz CPU, 1MB
RAM, cca 10MB free space on HDD). That old comp I use now to telnet to
my Pentium box running
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.

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
Hello Steve,
TKS for your comment about ARQ FAE. Yes it is a mix of DTM ARQ (for the limited
frames adjusted as needed by the number of characters to send), the DBM ARQ
(for the interleaved way to mix bits, before correction by the Golay decoding,
which permits to gain perhaps 2 dB on the
have been on 14109.5 with Terry, VE5TLW on and off all day , trying to get ARQ
FAE to work... finally had success, and it was something simple,
I had VOX delay on, and when my data stream ended, the TX stayed on for that
split second longer, partly covering up the response
from the other
Hello John,
TKS for info.

Yes VOX is too slow. ARQ FAE seems Pactor as frames are short (but not so short
as in Pactor) and the exchange fast. The RX/TX switching
It does work fine on my TS480SAT, using VOX but with the VOX delay
off looking forward to trying it over some distance

as of 0300Z beaconing on 3587.50 and ready to try 141A , the new multiPSK mode
. tried locally earlier and works like a charm

help you set it up

Hi John,
It worked really well despite me being a moron! Sorry to cut it short
due to work looming soon. Copied you and VE5TLW fine once I sorted
things outARQ FAE is most interesting!
thanks again,

no problem as i said I have a toll free here anywhere in North America so
can walk u thru it
sigs not real strong... but it is a great mode, Terry and I were fooling
with this earlier today and got it working between us
tnx fer the try

patrick ...
managed to connect briefly on noisy conditions with N9DSJ, and using long
frames. would have worked better with short frames
but is great working under very marginal condx...
looking forward to more experiments hi hi are you going to try 20m this weekend
?

Was fun...despite decades of reading raw packets on ax.25 and NOS,
setting display of messages only under options made it alot easier
later on. In spite my meger 15 watts and Pactor qrm it worked
surprisingly well; obviously a mode worthy of more experimentation.
Thanks John and Patrick
