Would someone remind me who was looking for switches for a Yaesu G5400/G5500
rotor controller??
I've searched on the AMSAT-BB archives, but haven't discovered the correct
keywords to retrieve his messages. I can probably help him.

Hi Steve. I can't hear the noise myself as I'm deaf in one ear, and no
high frequency in the other . But my wife and several neighbors assure me
almost every day they can hear it. What are your slider settings? Please
bring up your Green Heron s/w and take a pic of the settings . When I get
down there I'm going to have to do something as I don't want to upset my
neighbors anymore.
I should of mentioned on the 5500DC I was thinking of replacing the motors
AND the control box as one of the motors in my spare 5500 rotor is also
shot. So I would only have to buy one more motor to convert the system to a
DC motor one. I'm thinking of doing this as the AC motors don't appear to be
available anymore.
If I can't solve the noise issue I'm going to have to sell the Alpha Spid
and RT-21. I might as well buy a whole new Yaesu 5500DC at that point and
just keep the broke 5500 I have for spare parts for my older 5500 up here. I
just don't see why my setup down there makes so much noise...

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....

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

Congratulations on the successful demo.? Now take the next step.??Apply for
your own ARISS school contact.? If you are successfully accepted, then it
is even more fun. ?The info below has been posted several times recently but
here it is again.? Good luck!?73,Charlie Sufana AJ9NOne of the ARISS mentors?
The main page for Applying to Host a Scheduled Contact may be found at
https://www.ariss.org/apply-to-host-an-ariss-contact.html ???
?
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@?????.???.

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. ???In a message dated 2020-10-08

A good idea worth mentioning for those who haven't done one yet.
The ARISS contact I did with Mark Hammond, N8MH for Moore Square Magnet
Middle School in downtown Raleigh was so satisfying. The preparation and
set up and having all the kids cheer, and astronaut Scott Tingle try to
convey that he was just as excited as us (hard to believe but it seems a
lot of astros say that), was so much fun and so rewarding.
Here is the video:

P.S. thanks to Roy for receiving the pass from his QTH and sending me the
audio. I was so excited when I ended the contact I talked over Scott when
he thanked me and the father of the student whose ideas the whole thing was
(Jim Scarborough, KE4ROH). Wouldn't have heard that otherwise.

I believe that was me several months ago. I waltzed around with Yaesu
getting one. They sent me the switch without the paddle (my paddle was ok).
The new switch did not fit the old paddle. I could have just jury rigged a
switch but I tried one more idea. I called Yaesu repair and nicely asked
them to go to the back room and take a trashed control unit and just send me
a switch. They did, it worked. There must be as better way.
