Re: Is the ISS FM repeater now dead?

David Spoelstra
 

Can you enlighten me as to why AMSAT-NA not having any operational satellites is "very concerning"? From my standpoint, as long as there are satellites I can use I'm happy. Also, isn't AO-7 an AMSAT-NA satellite? According to the current status page it's working.

I know AMSAT-NA has had some bad luck, but I believe things ebb and flow. For a while, the US had to depend on the Russians to get to the ISS. Now, SpaceX is turning into a regular bus!

I personally don't care who puts up some FM transponders, I just wish they would hurry! 😀

Is the ISS FM repeater now dead?

David Spoelstra
 

I just read the AMSAT bulletin. Am I reading it correctly that the ISS antenna cable replacement went bad and now the ISS repeater is down for probably quite a while?

That would mean that we only have three semi-working FM birds left: PO-101, SO-50 & AO-27. Bummer...

Not a problem. We all tend to skim over sometimes. This was not directed towards you specifically, I was trying to mention to several people at the same time. maybe I didn't do the reply thing at the correct location. My hope is that someone would be able to help Chuck out somehow though or he might be able to purchase a QFH from either the site I suggested or another site that makes and sells QFH antennas.

Tks Clint,  I found it now in the NORAD database.  They're still showing it as "Object M", but as long as the TLE's are accurate ....

If you take the time to read Chuck's message, he states he is handicapped and making an antenna is out of the question. I found a site that makes QFH antennas and a friend of mine here in Milwaukee, WI has purchased a couple of these and says they seem to work pretty good. Here is a URL link of that site. The other option would be if someone made one for Chuck to use. I see Chuck lives in SHAWNEE MISSION, KS. Anyone near him that could build a QFH or any other antenna he could use to listen to the birds?
https://www.antennas.us/uc-1464-531-vhf-qfh-amateur-satellite-antenna.html
Chuck, look this site over and see what they have to offer.

QFH antennas are easy enough to make, quite a few plans online but they
are fiddly

they are also mainly used for NOAA WX sat reception as they are for
circular polarised signals

an easier antenna to make with similar properties is the turnstile
antenna, also a lot easier to make and tune

Re: Fox-1E Launch Window/NORAD IDs

Floyd Bixler
 

I'm having some issues locating any real ID's for FOX--1E.  The 79001 ID comes up negative, but if I search the NORAD database for launches on 17 Jan, 2021, I get 10 entries, all not fully identiied and the ID's are all 473XX numbers.  

I can track and try to receive the transponder signal but would like to try to pin down the ID better.   The other option is to monitor the orbits of those sats and maybe pick it out.

Tks.  Hope we can pin this guy down now that some type of signal is there.

ARISS Operations Situation

January 28, 2021 -  I sent this e-mail to our ARISS team today.  I felt it is important that you see this too.  ARISS will get through this issue.  And, as you can see, we have some work arounds to keep our school contacts moving forward.
 
For those that do not know radio shortcuts—73 is short for “best regards.”  It is a term amateur radio operators traditionally use at the end of our radio conversations.
 
ARISS thanks each of you for your tremendous interest and support to our program.

Frank Bauer
 *********************

All,
 
Today was a tough one for ARISS.  Let me explain.
 
As you all know, an EVA (spacewalk) was conducted yesterday to install cabling on the exterior of Columbus to support the commissioning of the Bartolomeo attached payload capability mounted on the Columbus module.  On January 26, prior to the EVA, our Columbus next generation radio system was shut off and the ISS-internal coaxial cable to the antenna was disconnected from the ARISS radio as a safety precaution for the EVA.  During the EVA, our current external antenna coaxial cable, installed in 2009, was replaced with another one built by ESA/Airbus with four RF connectors included, as compared to the current 2 RF connections.  This change was made to allow ESA to connect ARISS and 3 additional customers to Bartolomeo, as compared to ARISS and one additional RF customer.   As you might have seen yesterday, the EVA was conducted and our cable connection was swapped out.  This morning, the crew restarted the radio system.  Not hearing any Voice Repeater reports, we requested a switch to APRS packet.  We still did not hear any downlink reports.  At 1746 UTC we had a planned ARISS school contact between our certified telebridge station ON4ISS, operated by Jan in Belgium, and Mike Hopkins on ISS.  No downlink signal was heard during the contact.  The crew radioed down “no joy” on the contact about halfway through the contact and the Newcastle High School, Newcastle Wyoming, USA contact attempt ended.   
 
Clearly, there is an issue.  More troubleshooting will be required.  It may be the new external RF cable that was installed during yesterday’s EVA.  It might also be from the connect and disconnect of the interior coaxial (RF) cable.  So the interior cable cannot not be totally discounted yet.  The crew took pictures of the coaxial cable and connector attached to the ARISS radio inside the ISS.  Because the exterior cable is a Bartolomeo cable and not an ARISS cable, we are working with ESA and NASA on a way forward.  NASA has opened a Payload Anomaly Report on this issue.  We have talked to both the NASA and ESA representatives.  These are the same folks that worked with us on previous ARISS hardware systems as well as the ESA Bartolomeo integration initiative.  We have also asked our Russian team lead, Sergey Samburov, if we can temporarily use the radio in the Service Module for school contacts until we are able to resolve this issue.  As we gather more information, we will share it with you.
 
On behalf of the ARISS International Board, the Delegates and the entire team, I want to thank all of you for your tremendous volunteer support to ARISS.  We WILL get through this and be more resilient as a result.
 
73,  Frank

Max-

It's sad when we lose any satellites since there are so few. Hopefully it comes back alive or we "find" it on another frequency.

On a brighter note, UVSQ-SAT with an FM transponder has been heard a bunch and it's already on the AMSAT current status page. I'm looking forward to when we can use it!

He specifically asked for FM satellites. Fox-1E is a linear transponder. It got "upgraded" from the original FM transponder:

If you meant AO-91 (Fox-1B) or AO-92 (Fox-1D) then yes, they are on every now and then but it's been about a month since the last time I heard them. AMSAT's live status page: https://www.amsat.org/status/ shows that they have both been silent for the last six days. For everyone - if they are working, ONLY WORK THEM IN SUNSHINE like it says on my chart.
