My first pass is just after noon. If it hasn't self-corrected by then, I'll
try a reset.

Hans,

Looks like if it IDs, the signal is normal and you get the usual 2 telemetry
frames.  If the transponder has been brought up, you get the odd signal,
with a brief switch to DUV at the end, but no telemetry.  The command staff
have been notified.

Absolutelyl, no worries about doppler. The only one of concern was the 1200
Hz error and I think that was a typo. I'll look for the update. Tnx so
much, it is a wonderful asset to sat ops. 73, N0AN

Karl Janski was an electrical engineer employed by Bell Telephone. In
the 1930's he was given the task to help find a means for trans
continental communications . While researching the 20 mhz spectrum he
can across a strange hiss that showed up several minutes earlier each
day.? He suspected that it came from the Milky Way Galaxy.? He did not
pursue looking into the phenomenon as his employer had other work for
him to do.

It was Grote Reber, W9GFZ, who really started researching radio sources
in the sky.

Both Janski's and Reber's radio telescopes are on display at the
National Radio Astronomy Observatory at Green Bank, WV, the home of the
world's largest steerable radio telescope.? If you ever get near the
area, a stop at the facility with its many telescopes and excellent
visitor's center is a MUST.

The observatory's radio club has been granted Reber's call, W9GVZ, They
use it to commemorate radio astronomy in special events.? I spent
several summers as a physics teacher studying radio astronomy at Green
Bank and was able to help operate W9GVZ during a special event? at the
dedication of the Robert Byrd Telescope in August, 2000.? I have to tell
you that Green Bank is quite a place.? I get back there as often as I can!

I cycled the power to the IHU and it popped right back the way it should be.
Should be fine now, but reports for the next day or two will be appreciated.

Looks much better all right.  If cycling the  IHU fixed it, that does imply
it was an IHU problem, although we could have guessed that the tx was ok,
since we were getting telemetry ok.  Since the IHU cycled ok, that implies
that it was not the program memory.  Given that we got telemetry in idle
and for a few seconds after the transponder went off, that means a lot of
stuff was ok.  I'm guessing that probably some bits got flipped in the data
for the software high pass filter, which would explain why there was trash
in what should have been the telemetry audio frequency band (below 200Hz).

Nothing heard from AO-91 on pass over EM79 a few minutes ago. Sometimes
it's me, so if somebody else was able to transmit through the bird, go
with that.

What time did you have for the pass?

The last pass started around 12:13 pm EDT. Next pass is around 1:48 pm.

I warned you it might be me. For some reason I used the time for the
pass coming up on Friday. Maybe I need a nap.

How much trust does one have WRT state boundaries and what Maidenhead
displays? The borders are often not straight nor do they always align with
Lat/Lon ... looking at Wyoming, we seem to have 8 more grids than our
rectangular shape would have one believe (some from Colorado and others from
Montana).

Anyone else see this or similar?

Thanks and 73,

Subject: [amsat-bb] Yaesu GS-232B Rotor Interface to computer RS-232C
Port	Help!
Message-ID: <82428f8d91a41bacf4929efc40b13316172b2f5b@>
Content-Type: text/plain; charset=UTF-8

Hello list members,
I have a new Yaesu GS-232B I'm having connection issues and could use
some help.
My system is a Dell XPS running Windows 7 Pro. Terminal emulator is
PuTTY.exeThis computer uses a real RS-232C port set to the only choice
of COM1. No COM2 port, parallel or printer ports are used with this
machine.
Port settings are 9600 baud, 8 bit, no parity, hardware control set to
none.
I'm sure my computer, RS-232C port and strait RS-232C cables are good
because I have no trouble connecting to another device. (Juniper
CTP-1002 router)I tried all combinations of hardware control options,
port speeds and always get a blank screen with only a cursor when
connected to the Yaesu GS-232B.

Anybody have any suggestions what I might be overlooking?
Thank You,
N8OCX
Brook Smith

I'm seeing the same signal here. The beacon sounds fine, but no audio on
the transponder https://imgur.com/a/UvWxaA2
