I am opposed to supporting a commercial product whose owner requires that
you allow them to take your content and do whatever they want with it. They
can also let other companies do whatever *they* want with it without
telling you. Thus I won't create a Twitter account. Make no mistake, by
merely creating an account, even if you don't use it, you are supporting
the company, since they make money based in part on how many user accounts
there are.
Fortunately, we have this BB, which is a more appropriate channel for a
non-profit and its members. But if you feel that you have to use Twitter,
note that you can view any user's feed without having to create your own
account. If you need notifications, you can use a service such as IFFTT.

The 01:45 UTC pass , several minutes ago, over OI33JR the SSTV sound is back
to normal and got good images.

Good passes here, too.
So, with the dust settling on this little adventure, do we know what
happened? What rigs were in use for what roles? Where was the
interference coming from?

I would say to get on Twitter, but you need to stay on top of your feed. I
don't get any political items in my feed, I only allow Ham items, and mostly
Satellite. I can safely say that without Twitter I would not be where I am
in my grid chase or my knowledge of operating sats.
If you put post your pollical feelings I block you. If you cause drama, I
block you. If you posting good clean fun items about Satellites, I will
follow you. This process takes about 2-3 minutes a month and is time well
spent.

I'll give you my take on it. My initial report looks like local
terrestrial interference because the waterfall seems to show a very
strong signal centered on 145.8 over the slightly doppler shifted SSTV
signal as can be seen here:
https://www.dropbox.com/s/dxmy4rhruiit84v/funny-sstv-signal.png?dl=0
I would like to think it was non-malicious as that doesn't seem
likely, but it coincided very closely to the start of the next SSTV
transmission and was nearly the same bandwidth sounding SSTV-like, but
not quite. Maybe the sound was due to some mixing of the two signals,
but I don't think that would produce the sound I heard. The second
issue started when the SSTV transmissions went silent around 15:00 UTC
on 10/6 as can be seen by all the read reports here:
https://amsat.org/status/
The first block of red reports was due to the Cygnus docking on 10/5,
but it came back later that day well before they said it would resume.
It was up for several hours and went silent on 10/6 for a reason that
I don't know yet. When it came back, the pictures were distorted for
several passes I tried. This time, it looks like the signal itself and
not interference. Maybe the audio was mis-adjusted and distorting, but
I had near perfect condition and even did some post-processing and
doppler shift correction with the raw, baseband signal after the fact
and it still produced an ugly image. I could even see the ISS during
the pass and visually track it with my handheld Yagi. This was 02:00
10/7 UTC. Here's the best I could get out of that pass:
https://www.dropbox.com/s/a3ibnks6ionwwt2/bad-sstv-202010071920.jpg?dl=0
The next day (for me) at 18:30 10/7 UTC, It was much improved and I
captured this on my phone directly without any post-processing or
doppler shift correction:
https://www.dropbox.com/s/39feej142tn9gcd/20201007_133152.png?dl=0
I've captured multiple images on several passes since with similar clarity.

Jeff,
I can answer two of your questions:
1. I have not heard the beeping or buzzing noise with my AlfaSpid.
2. The new G5500DC control box will most certainly *won't* work with the
old rotors. The new control box produces direct current drive for the new
DC rotors. This won't work with the AC induction motors in your rotors.
However, the AC G5500 control boxes appear regularly on ebay as they tend to
outlast the rotors.
Send me an e-mail privately. I may have a spare controller in my workshop.

Last year I went with an Alpha Spid setup at my Florida home. It worked
well with the supplied Alpa Spid controller for about 3 months. I then
started having issues with the controller relays failing. Over a 6 month
period I replaced them twice, when they failed again I decided to go with
the Green Heron RT-21 controller. All is working fine, I really like the
PstRotator software. It's a bonus that it has grid-click operation to easily
work terrestrial VHF and up with my sat antennas. The only problem with this
setup is the RT-21 causes the rotor to make a load beeping noise as the
motors ramp up and down. I spent some time on the phone with Jeff from
Green Heron to try and adjust the controllers control sliders to tone it
down a bit. I can get it somewhat quiet, but the rotors become very erratic.
They will over shoot the desired az/el by 20 or so degrees then swing back
the other way, for the entire pass. Not acceptable. It is such a problem
that I'm going to have to replace
the Alpha Spid with a spare 5500 I have. It is so noisy the neighbors
across the canal(250 feet away) can hear it. I'm getting ready to leave the
NJ QTH for Florida for the winter shortly. I'm going to bring my spare 5500
and burned out control box with me. So I have a few questions...
1. Steve, do you hear the buzzing noise in your Alpha Spid setup I'm
talking about?
2.. As I'm going to try and repair the Yaesu control box, I'm almost
positive that the transformer is burned out. If not available I might
consider buying a new control box. I'm thinking that the new 5500DC will
work with the older rotors?
3. Does anyone have the RT-21 working with the 5500? If so does it have
the same ramp up and ramp down noise issue?
Thanks for any info on this....

Subject: Re: [amsat-bb] Fox Telemetry antenna?
Kevin,
I'm in West Lafayette, Indiana, so no salt water. My antennas are
M-squared medium size antennas, 2MCP14 and 436CP30 with polarity switches,
so not overloaded.
Mark N8MH, has had similar experience with his Yaesu's. Since he is a
dedicated telemetry collector like you, and since he is a control operator
for the Fox satellites, he replaces his rotors when they fail. He had a
volunteer to repair his broken rotors, so I transported 6-8 rotors from his
garage in North Carolina (not near salt water either) to Indiana. Half were
elevation rotors, half were azimuth rotors. I thought I was just having bad
luck until Mark shared his experience.
The last time mine failed, it was the azimuth rotor. Pointing the Yagis
south just above the horizon worked a little better (long term) than an
omnidirectional antenna. Since it failed while I was on a 3 month trip, I
couldn't replace the rotor.
I still recommend the G5500 rotors for normal operators, but they may
not be the best choice for 24x7x365 telemetry collection. (I'm glad they
work for you in that mode.) I've since switched to an AlphaSpid rotor with
a Green Heron controller. You can buy the AlphaSpid rotors without the
controller (my recommendation for heavy duty use) and use a Green Heron
instead.
Still: YMMV

Steve,
What are you doing that is wearing it out in 4-8 months?
overloaded?
near the ocean with salt? something has to be wrong as mine go for
years.
