Hello,
I am very interesting to know how many peoples in the world have my, and not
only mine..problem for receive ISS SSTV on 145.800. The problem is the
repeater (7a) at 145.787.5 and ISS , for doppler naturally go down 145.800
and its impossible to receive well if someone talk on repeater.
Thanks for attention.
Carlo IK5JRZ.

This situation doesn't happen in IARU R2, as 145.790-145.800 is a
protection segment.
In IARU R1, there is no such a protection, suggest request change thru
your IARU Rep.

According to the band plan reported on the ARI web site, the space
communication band is protected starting at 145.794 Mhz, i.e. 6 Khz below
145.800 Mhz. The R7a is indeed at 145.7875 Mhz with a bandwidth of 12 Khz
there shouldn't be any interference (in theory). Have you checked which
repeater is in your (our) zone ?

Remember due to Doppler shift the ISS signal can be as low as 145.7965 MHz.
While the Necessary Bandwidth of the repeater on R7a would be about 11 kHz
the FM sidebands will extend beyond that and make it impossible for any
local stations to receive the ISS downlink.
It is unfortunate IARU Region 1 chose to put a repeater channel so close.

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.

Thanks for answer,
The repeater is R7a (Monte Secchieta), it's not only an Italian problem
unfortunately, I have read many complaints in other areas as well. I don't
question the correct spacing between frequencies, but I'm afraid it's only
on actual paper. I don't want to doubt that the repeater is working
correctly, but I think that if the ISS transmitted at 145.825, since when it
transmits in SSTV APRS is disabled, the problem would be solved. The video
demonstrates the proximity between the frequencies even if I admit to being
in the high area and to receive the repeater very well.

Ogg: Re: [amsat-bb] ISS SSTV frequency
According to the band plan reported on the ARI web site, the space
communication band is protected starting at 145.794 Mhz, i.e. 6 Khz below
145.800 Mhz. The R7a is indeed at 145.7875 Mhz with a bandwidth of 12 Khz
there shouldn't be any interference (in theory). Have you checked which
repeater is in your (our) zone ?
