All,
Received a few e-mails about not being able play the the digital voice
recordings on my site. It seems to be a firewall issue in most cases and
temporarily disabling it should allow access.

Certainly hope we can resolve the codec issue and get back on the

Just on a side note, yep I have dabbled on HF packet, just connecting to
european nodes etc. Never had much success, I'd have thought NVIS on 80m be
quite good.
Anyway there are some promising HF sound card ARQ modes coming out at the
moment,
Like psk mail and flarq for FL digi (even
Thanks for your input, I do have MultiPSK and will look into as well I will
look into MixW, Yes to your responces with all the other modes provided from
other programs, However I am looking at Satelitte Packet 1200 , So tnx agn 73

The closer you are to the MUF with a path between two points often
results in the most stable path. That is why HF packet worked well
during peak times of the sunspot cycle where higher frequencies,
especially 10 meters worked very well.
I have used fldigi on both Windoze and Linsux operating
Similary, I have used Multipsk's packet modes on both HF and VHF with
success. With the advance of technology, I moved away from packet around
15 years ago! It is just not robust enough for HF and can only go a
short distance on VHF, compared with newer modes
What seems like an unfulfilled

GM Jose,
There is one point in your post I would like to bring up. Where you
say:
Multitasking cannot handle tight ARQ timing windows.
It is a pity that noone has come forward (as far as I know) a real
time OS (RTL, for instance) with a proposal usable on an

SCAMP had no problem at all with the switching times from the testing I
did. As a former Amtor and Pactor user from years earlier, it proved to
me that my concerns about switching were unwarranted. Then along comes

Is this a digi repeater mail box or just a beacon ? i rx a couple of

Good question.
For the most part is has been used to post you APRS position as a DIGI.
Some (and this has been a pet peeve of mine for years) seem to want to
have a QSO. That just causes many many retry's and one one can use the
system. Yes there is a BBS on board. But using it will really screw

Graham, yes it a Digi repeater on the ISS. I was using MultiPSK 4.11.1 but for
me to get to work in the TX mode I would have to pay for the program, or you
can get 10 mins free. I have used up my 10 mins. I can only Rec now. Looking
for a free program that will do 1200 BPS Packet to work ISS

Cold switching (no RF until contacts are closed, or opened while RF is
flowing)
Hi Russell,
I had thought that the Multipsk mode that required payment was some kind
of digipeater built-in to the program. But shouldn't 1200 baud packet
work without any time limit? I do not recall a time limit on the
versions that I have used in the past.

Hi Jose,
The advantage of using manual ARQ fills after the transmission of the
data, is that it can be used as a one to many transmission. If any
stations did not receive the data perfectly, they can send a request to
repair defective portions. This is not possible with a handshaking type
Rick, Yes you might be right, the APRS and Packet will work in Unproto mode, I
need to read some more about this and see why I can get the software to key the
radio, Hower other programs does key the radio. just some setting somewhere.
Thanks Russell

Correct me if I'm wrong. But reading between the lines of you post
on this subject I feel you are saying -
don't hold you breath for a sound card mode that will replace the
ARQ modes such as Pactor or Amtor.
John, W0JAB
Hi John,
Amtor was never that good. If you recall, it would start allowing
erroneous data through when signals become weak enough. And when that
happened, the signals were of what we would today call reasonably good
signal strength for PSK31, MFSK16, etc.
Pactor was much better. I did not
