Hi guys..
The new version is now available from the MM Hamsoft website.
MMVARI Ver. 0.42 Beta has only minor changes. The main
It is too bad that packet could not have advanced with new technology to
make it work well on HF. In order for it to be able to work under many
conditions, it needed to have the agility to change baud rates/packet
sizes to match those conditions and it was really only designed for VHF
and for
My view would be that any change to the packet RADIO
system to utilize the internet was a step in the
direction of eliminating it altogether. The value of
packet radio is the emphasis on the radio part. Once
you say the system would be more useful if the end
result was email, then why utilize
It seems I should state the part of the history I have lived.
1n 1991 I started with my C-64 and KPC-2 as user of several HF BBS's, on
different frequencies, surfing the NETROM nodes, etc, until I
settled as user of YV2AEH on 14095 LSB. It solved a problem I had
not been told : stable mail
Well, the internet was reality and there was no way to stop it. The only
way that radio amateurs could have prevented the linking to the internet
would have been to making it illegal and I don't think many would
support you on that.
Radio by itself has a benefit. Primarily an emergency

E-mail is tremendously more useful than the hierarchical packet
system because it works not just for hams, but for anyone with
e-mail, which is ubiquitous in countries such as the U.S.
What I wish for is a system that could do both.
Most xNOS can do it. Say, GRINOS, TNOS,

This is certainly lost on the Pactor III group.

having many small bandwidth users means more throughput for more
users than one large bandwidth user at a time.
Jose's comments have been helpful. I used VHF packet in the old days and
also used the first satellite gateway on the east coast. run by my neighbour
down the street!
When I started this thread I had one goal in mind, a simple way that hams
can send brief email without use of the Internet ,
Hi Andy,
A system that implemented the ALE Data Block Message (DBM) ARQ
protocol using the PC Sound Device Modem (PCSDM) which at a raw 125
baud with its deep interleaving providing a full 3x throughput on a
good circuit where no ACK/NAK failures occurred would be much better.
GTOR which
When you are using xNOS aren't you also needing to be using TCP/IP with
considerable overhead? From what I have understood, using xNOS on a 1200
baud system is not really practical although at 9600 baud it is OK.
Having said that, I know that JNOS2 now supports both HF and VHF.
Unfortunately,
Steve and group,
The part of ALE that has this ARQ mode sounds pretty good. Is it fair to
say that the 8 tone modulation is actually closer to what Pactor 3 uses?
The speed is a bit fast for many HF conditions but it has FEC as well as
ARQ so like Pactor, is that why it tends to overcome some
Hi all,

What software is available that will do MFSK with pictures, aside from
Multipsk or Mix-W. Does the newer version of Stream have it? Thanks

Hi Rick..
You understand it exactly right. There are a few HF
users, but most of the product of our efforts are VHF
stations running bulletin boards who receive the
messages by VHF nodes which are part of the HF packet
station setup.
We're just a bunch of stubborn
I agree with Bill, there is a need for a short haul message system such as
winlink, or a 300baud system which could work into an internet gateway
For example, an area hit with tornado or other natural disaster which would
disable the internet in the immediate area.
This should work on HF since
look at OLIVIA, have worked QRP stations on 80M out 1000 miles

I returned to playing around with Ham Radio Deluxe and MMVARI tonight.
With the specially designed HRDPTT file, they work together quite
well. This gives you the full rig control beauty of HRD and the PSK,
RTTY, MFSK16 modes within MMVARI. I assume I am correct in deducing
that the two in
My view is that PSK31 is the most efficient from a spectrum usage and power
usage point of view. Other modes have better error correction facilities but
occupy more bandwidth. Olivia does a very good job copying signals that you can
barely hear or see on the waterfall. For most people, 20 to 25
Hi Rick,
The U.S. Declaration of Independence of late has become a popular
MARS EXERCISE test message in testing MARS-ALE and with ALE DBM ARQ,
that as the body of the message along with the standard MARS message
header and tail takes just over 6 minutes if there are no ACK/NAK
failures

amateur radio frequencies until it has an easy to access
