Amateur Radio Relay League (ARRL) Generously Awards a $3,000 Grant to
Support the Open Research Institute (ORI) Amateur Radio Satellite Service
Research and Development Program
ORI, a 501(c)(3) dedicated to open source research and development in
amateur radio, has been awarded a $3,000 grant from the ARRL Foundation.
This grant, the maximum amount, will be immediately applied to Phase 1 of
the Digital Multiplex Transponder research and development program. This
grant allows hardware prototypes for broadband microwave digital payloads
to proceed much more quickly.
All work completed by ORI is made available to the general public at no
cost.
A project that will directly and immediately benefit from this work is the
Amateur Radio Exploration (AREx) project, brought to you by Amateur Radio
on the International Space Station (ARISS). ARISS is a project sponsored by
the Amateur Radio Satellite Corporation (AMSAT).
AREx is devoted to designing and building amateur radio equipment for the
Lunar Orbiting Platform Gateway project. This lunar orbiting station will
have open source broadband microwave amateur equipment and affordable open
source ground stations. AREx is not limited to Gateway, as there are many
other opportunities under consideration that can re-use what is designed
and built.
Documentation about the transponder program that this award supports can be
found on the ORI website at the following links.
Overview:

Technical proposal:
https://openresearch.institute/2020/01/10/p4xt-digital-multiplexing-transponde

Phase 1 statement of work can be found at the summary document linked
below.
Summary:
https://openresearch.institute/2020/02/21/summary-proposal-open-research-insti
tute-phase-1-p4xt/
Established in 1973 by the American Radio Relay League, Inc. (ARRL) as an
independent and separate 501(c)(3) organization, the ARRL Foundation
administers programs to support the Amateur Radio community.
Funded entirely by the generous contributions of radio amateurs and
friends, ARRL Foundation administers programs for Amateur Radio award
scholarships for higher education, award grants for Amateur Radio projects,
and award special Amateur Radio program grants for The Victor C. Clark
Youth Incentive Program and The Jesse A. Bieberman Meritorious Membership
Program.

Want to get involved? There has never been a better time be a microwave
enthusiast in open source amateur radio!
Contact Michelle Thompson at w5nyv@????.??? for help in getting started or
for any questions or followup about this announcement.
Here are some of the organizations that will appreciate your time, energy,
effort, and enthusiasm.
ARISS is the home for AREx. ARISS can be found on the web at
https://www.ariss.org/
AMSAT North American is the home for ARISS. AMSAT is active in AREx in
multiple roles and can be found on the web at
https://amsat.org
JAMSAT supports AREx and has partnered with ORI to work on the Gateway
Ground Station. JAMSAT can be found on the web at

A series capacitor (experimental value until you hear the change in pitch on
another radio) will boost the high tone. A parallel cap to ground
(experimental value) can reduce the high tone...
ARISS reports that the ericcson radio on ISS is quite deaf and so needs to
hear some power. Also, they are not sure if the ARISS alias works. Try
RS0ISS.

Subject: RE: [amsat-bb] unable to dig over ISS
If the ISS radio is the Kenwood D700, it is quite sensitive to unbalanced
tones. So your base station might work well with a local digi, but if the
low tone is higher than the high tone by just a bit (or other way around),
it will not be decoded by the D700. This is because the kenwood is
optimized for flat tones (at the discriminator) not pre-emphasized as most
people do when they hook up an external TNC to the mic circuits.
(I may have the tones reversed). One of them can be higher than the other a
bit and work fine. The other way around it simply will not work.

Thanks Umesh. Well I would agree except that several nights ago I pulled out
the D7 HT and elk, and digipeated numerous times on a nigh pass.
Immediately went to the base station and tried but no dice. Plus, on every
pass Ive tried on my base station, I see the stations I decoded show up on
the ISS spotter. So it remains as issue at my end.

Subject: Re: [amsat-bb] unable to dig over ISS
Looking at when the problem started, I'm assuming the problem is related to
ISS turning off their packet systems regularly.
Long ago I was able to operate ISS packet throughout the pass, even drop
messages into their their BBS, etc., but for a considerable time now I have
pretty much given up working with ISS packet.
All other factors considered, the fact that your system gets ACK-ed on
144.390 is proof positive. It has always been a guarantee to be able to
work ISS packet.

Doppler and rotor all run by SatPc32. Up to about a year ago I ran AGWPE

finally removed AGWPE and began using Sound Modem with UISS.

My transmissions sound like normal packet transmissions, listening on a

Sound Modem and UISS. I have played with the audio levels. I substituted
Signalinks in case that was the issue. Also, I have no problem sending APRS
over 144.39 using different "wide" settings and getting an acknowledgement
back. My "neighbor" Christy KB6LTY has provided mu ch assistance, but still
no joy. I am missing something. So I'm hoping someone has had a similar
issue with a similar set up and can maybe send me screen shots of their
settings that work, especially in Sound Modem.
Or, any other suggestions would be greatly appreciated.

Thanks Bob. Not sure but I seem to recall that sound modem has a tone
calibration function which may allow me to do as you suggest. I have
regularly tried RS0ISS. Both ARISS and RS0ISS used to work fine for me.

Hi
Prepare for E2STAYHOME on NB mode for Es'hail 2 QO-100 geostationary
satellite in end of this weeks. Thailand's regulator the National
Broadcasting and Telecommunications Commission (NBTC) has issued a
special callsign to The Radio Amateur Society of Thailand founded
under the royal patronage of the King of Thailand (RAST). which is
E2STAYHOME. RAST will be operating using this callsign on all bands
and in all modes. For details will be comming soon.

Here is another version of the same idea that is more plug and play. Uses a
