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

I haven't been doing any sstv decoding, but on a

Was it a female russian voice? They have a system that announces the
locations they are passing over and it gets into SSTV transmissions
somehow/sometimes.

No,

Content-Type: text/plain; charset=UTF-8
?I've been trying to use MMSSTV to receive the ISS pics, but I'm having
problems. I think the problem is with syncing. I can see that I am receiving
strips of various colors, but they are not lined up to make a coherent
picture. ?
I downloaded the latest version of MMSSTV yesterday so that's ?up-to-date.
I'm using SDR# to decode the signal from a dongle. The output of SDR# is to
the input of VBCable and the input to MMSSTV is from the output of VBCable.
Once I've downloaded the picture I can hit the "fix slant" and "fix sync"
button and the picture straightens out some but still not enough to see the
details.
The op system is Windows 10.
I've read through the MMSSTV help and can't find a fix.I must be missing a
setting somewhere. If anyone has ideas to share on how to fix this, I'd
appreciate your help!
(Is there a better SSTV decode program?)

Hope you don't mind that I shared your email (below) on-list, but I think
you gave me a clue as to what I'm doing wrong and I would like folks to see
a good example if they need it.
Your screen shows the single peak at 1200, then essentially nothing until
the picture info between 1500 and 2300 , then down to nothing again. I also
noticed that the little green signal strength (?) bar just to the left of
the FFT display is quite low.
I think maybe I've just had the input level up too high. I've got signal in
the FFT portion all the way from 1200 to past the 2300 and the green bar
about 1/3 of the way up it's range. Would that be enough to throw off the
sync?
I may be able to clean ?up the signal just by turning down the volume.
All helpful comments and suggestions are still very welcome.

Hi Steve,
The SSTV signals from the ISS yesterday were kind of garbled. ?Multiple
stations reported this, so it's not your (or my) station's problem.
Take a look at a video of a (good) pass on Monday last that I did for
our club:
https://www.youtube.com/watch?v=Z_SkJ8_mtA4
The FFT display should show the specific peaks in the signal around the
line sync on the left, and a separate band for the actual picture to the
right of it. ?If it looks like an amorphous blob, that was the
interference we all heard. ?Hopefully they'll get it sorted out upstairs
and we can grab a few more pictures today. ?Next pass in just under an

Hi Steve,
Not a problem. I should have done a reply to all...
The volume was turned down because the video recording software was
complaining about it being too high. Normally, the bar graph on the
left is up about mid-scale. You certainly don't want it pegged.
The "amorphous blob" I was talking about was due to the interference we
heard yesterday. Pass in progress right now... First image just
finished as the pass started, and it sounded clean. Good luck!

Hello Roy,
I Just tried during last pass for Europe but only 5 degrees for my station.
When I sent a packet to CQ via ARISS I heard NA1SS but his modulation was
very low and I decoded nothing.
I will try again tomorrow.

Roy,
I was able to digipeat packets on the last two ISS passes over
Arizona, and see packets from other stations. It is easier to
hear the downlink with 10W from the ISS, even at lower elevations.
I was using my TH-D74 at 5W, along with my Elk log periodic.
I think ariss.net is set up to display packets with RS0ISS
somewhere in the packet path. I e-mailed Steve K4HG, who owns
that site, to ask him about making whatever change the site
needs to display packets relayed through NA1SS.
I was able to search aprs.fi to see some of my packets that
were digipeated on the first of the two passes I tried this
morning. This means there are gateways still in operation,
even if I can't see myself on ariss.net right now.
I have a couple of decent ISS passes tonight. I plan on
giving them a try, and see if the 10W downlink helps to
overcome interference from lighting on houses around mine.
And try to make some QSOs.
73!
