Hi Bob!
I tried NO-84's digipeater just after 8.15pm Eastern time
tonight (0015 UTC Sunday). It came by about 15 minutes before
the ISS. A quiet pass, with only one other station on. The
last telemetry packet I picked up at 0022 UTC had #184, so I
think it is holding up for now...
I didn't try a double-hop. I was just hoping it would still
be active, and it was. Once it was up from the horizon, it
was easy to copy for most of the pass here in central Arizona.
73!

This was just the first of what we expect will be an ongoing series of
meetings, so we didn't advertise it very widely. Our initial notice went
to the "net 44" (TCP/IP over amateur radio) group that gave rise to
ARDC. Much of the meeting reviewed the results of a survey that also
initially targeted the net 44 group, and based on the responses and
comments we will update our surveys and solicit responses and comments
from a much wider audience.
But I can summarize some of the salient points we made yesterday.
The NDA with Amazon that covered the sale of our surplus IP addresses
required us to keep the exact dollar amounts private until we were
legally required to disclose them in our annual tax filings, audit and
financial reports. These have just been made public and are available
online through the California Attorney General's website (since ARDC is
incorporated in California). You can also get some background
information through our (independently written) Wikipedia article.
The bottom line is that the sale netted us about US $108M, and we expect
to grant at least US $5 million *per year* on an ongoing basis,
depending on how our investments perform, to a wide variety of Internet
and amateur radio digital communication projects. To date we have made
about $2.5 million in grants, so we're only getting started.

Does anybody have experience with this combination? I've been having
issues with my dedicated FoxTelem Raspberry Pi station, so I've taken it
down in favor of my APRS SatGate (which uses an RTL-SDR instead of the
FCDPP) - and decided to use the FCDPP for my Rx in my normal everyday shack
operations. However I can't seem to connect to the dongle at all with
GQRX. GQRX is doing something, but there is no waterfall and no audio.
I'm somewhat concerned that the issue with my FoxTelem station was with the
dongle itself, as I seem to remember successfully connecting to the dongle
with GQRX in the past. I've tried the dongle on two separate pcs
running Ubuntu 18.04 with no luck. I am able to start FoxTelem on a
raspberry pi and it seems to start decoding as expected (however the
failure mode is when it's left unattended for a couple of days, it ends up
stalling with a USB access error).
Any suggestions welcome. Thanks.

I knew it would only be a matter of time before a Hackaday article on this
would be posted:
The Cable Modem To SDR Transformation
https://hackaday.com/2020/10/10/the-cable-modem-to-sdr-transformation/
The link to stdw's Github.io site provides a lot more information:
Reverse engineering my cable modem and turning it into an SDR
https://stdw.github.io/cm-sdr/
The webpage is an interesting read, if you are in to this sort of hackery.
The cable modem is a Motorola MB7220. The Wave file of the received FM
radio station is a bit rough and a bit over-driven, but very good for
someone with little RF experience, but a desire to try and learn.
His webpage also references an SDR project that uses and Analog Devices
cable modem chip:
Hermes-Lite
http://www.hermeslite.com/
It is far too easy to go down the 'rabbit hole' on this stuff!

ARISS Contact Applications (United States)
?
The Amateur Radio on the International Space Station (ARISS) Program is
seeking formal and informal education institutions and organizations,
individually or working together, to host an Amateur Radio contact with a
crew member on board the ISS. ARISS anticipates that the contact would be
held between July 1, 2021 and December 30,
2021. Crew scheduling and ISS orbits will determine the exact contact dates.
To maximize these radio contact opportunities, ARISS is looking for
organizations that will draw large numbers of participants and integrate the
contact into a well-developed education plan.
?
The deadline to submit a proposal is November 24th, 2020. Proposal
information and more details such as expectations, proposal guidelines and
the proposal form can be found at www.ariss.org. An ARISS Introductory
Webinar session will be held on October 8, 2020 at 8PM ET. The Eventbrite
link to sign up is: https://ariss-proposal-webinar-fall-2020.eventbrite.com
?
The Opportunity
?
Crew members aboard the International Space Station will participate in
scheduled Amateur Radio contacts. These radio contacts are approximately 10
minutes in length and allow students to interact with the astronauts through
a question-and-answer session.
?
An ARISS contact is a voice-only communication opportunity via Amateur Radio
between astronauts and cosmonauts aboard the space station and classrooms
and communities. ARISS contacts afford education audiences the opportunity
to learn firsthand from astronauts what it is like to live and work in space
and to learn about space research conducted on the ISS. Students also will
have an opportunity to learn about satellite communication, wireless
technology, and radio science.
?
Because of the nature of human spaceflight and the complexity of scheduling
activities aboard the ISS, organizations must demonstrate flexibility to
accommodate changes in dates and times of the radio contact.
?
Amateur Radio organizations around the world with the support of NASA and
space agencies in Russia, Canada, Japan and Europe present educational
organizations with this opportunity. The ham radio organizations? volunteer
efforts provide the equipment and operational support to enable
communication between crew on the ISS and students
around the world using Amateur Radio.
?
Please direct any questions to?ariss.us.education@?????.???.
?
For future proposal information and more details such as expectations,
proposal guidelines and proposal form, and dates and times of Information
Webinars, go to www.ariss.org.

About ARISS:
?
Amateur Radio on the International Space Station (ARISS) is a cooperative
venture of international amateur radio societies and the space agencies that
support the International Space Station (ISS).? In the United States,
sponsors are the Radio Amateur Satellite Corporation (AMSAT), the American
Radio Relay League (ARRL), the ISS National Lab and National Aeronautics and
Space Administration (NASA). The primary goal of ARISS is to promote
exploration of science, technology, engineering, and mathematics (STEAM)
topics by organizing scheduled contacts via amateur radio between crew
members aboard the ISS and students in classrooms or public forms. Before
and during these radio contacts, students, educators, parents, and
communities learn about space, space technologies, and amateur radio. For
more information, see www.ariss.org.

The sampling part of the funcube dongle is an audio device from the view of
Linux. This means the audio subsystem will 'grab' it and make it available
to applications.
Run (may need to be installed) pavucontrol, go to the Configuration tab,
find the funcube dongle that will show as 'FUNcuble Dongle'
there and switch the 'Profile' to 'Off'.
Now try again with qgrx.
Changes you make with pavucontrol are saved automatically.

Roy, I'd be interested to know what problems you had with your Pi-based
FoxTelem, but I realize that you have gone beyond that.
One thought: I know one person who had issues with an FCDPP plugging into
the USB socket successfully. I tried several different sockets, and the
USB-3 socket (often with a blue interior) seems to work better/tighter,
probably not because of USB-3 but just the slightly different socket worked
better. You might also try a short "USB extension cord" to take the weight
off the joint.
Also, do the command lsusb on a terminal and see if it actually sees the
FCDPP. I think it is the one that says "Microchip Technology

I have a lot of experience with the Funcube dongle (the pro+ version) on
the RPi and x86. I've probably handled 10 of them, only one was DoA and
I don't think any have worked and later failed. But I do occasionally
see problems that require resetting the USB subsystem, which is probably
most easily done by rebooting. Have you looked at the kernel log? Use
the "dmesg" command, which you will probably have to run as root ("sudo
dmesg"). Also verify with "lsusb" that the system sees the device.
