YES I do.
Data was entered but something went wrong, need the entry data aging. It is

During the eclipse passes while copying telemetry with my Funcube Dongle
Pro + I am hearing SSB QSOs on the beacon frequency.
They usually "walk" across it but what puzzles me is that the website
info indicates that the transponder passband is well away from the
beacon frequency.
Am I experiencing some weird stuff with my Dongle or is it possible for
stations to work on an uplink that puts their downlink on the beacon
frequency?
Thanks,

I have heard that also, I figured it was someone hitting the sat so
hard that they are modulating the beacon.

Kimberly and I picked it up visually here in San Diego about a minute
before staging. Because of the high inclination (reportedly 123 degrees)
it was faint and far away, but it was unmistakable in binoculars despite
local light pollution. The plume was gradually broadening as it rose
into thinner air.
It disappeared at staging. I didn't expect to see the Centaur upper
stage at night since it burns H2/O2.
The primary payload is a NRO spooksat (reportedly radar imaging) so
coverage stopped at fairing jettison. No word on the cubesat
deployments, but they probably won't be for a while. Several are
supposed to transmit on 70cm.

That's an interesting observation Jerry. Not something we saw during
commissioning the satellite.
A possible cause would be image response of the dongle. Do you have the
'zero frequency' somewhere between the beacon and the transponder passband?
e.g. 145.945 or off to one side e.g. 145.920?
Other possibility is a large signal in the transponder passband causing the
beacon to FM. Is the modulation 'FM' or does it decode as SSB?
Thanks

Some weeks ago I saw Italian stations running vast amounts of power through
a transponder and causing the beacon to modulate heavily, can't remember
which satellite it was.
In fact these stations were running so much ERP that they took the entire
satellite out.

Twelve CubeSats are set to launch aboard an Atlas V rocket with the NROL-39
primary payload from Vandenberg AFB in California on December 5, 2013. The
CubeSat payloads have been provided through NASA's Educational Launch of
Nanosatellites (ELaNa) program and the NRO's Mission Integration Directorate
(MID).
CubeSat Project will be using the #cubesat IRC channel to coordinate object
identification.

I have two BOAFANG (SP?) that the club want to program for SO 50. and
possibly in advance for FOX 1. (I know that SO 50 has a tone.)
The questions:
* What freq should be programed for S0 50 to comp for Doppler?
* Same for FOX 1
Thanks everyone for their help.

Rich,
The answers to most of the questions you have been asking lately could be
found if you search the BB archives.
Here is a link to Clint's "how to" for SO-50 frequencies.

To use the two Baofeng radios on SO-50:
1. Program one memory channel for 145.85 MHz with a 67 Hz tone.
2. Program another memory channel for 145.85 MHz with a 74.4 Hz tone.
This channel will serve to turn on the 10-minute timer when required.
3. Next, program a set of memory channels sequentially: 436.805,
436.800, 436.795, 436.785, and 436.780 MHz
4. Use one of the radios as your uplink radio, transmitting on either
of the 145.85 MHz memory channels as necessary.
5. Use the other radio as your downlink radio, listening on
436.805-780. Based on my experience with Baofengs I consider them to
be slow in changing memories, so I would stick to the VFO-mode for the
downlink receiver. Manually set the VFO to 436.805 and adjust down as
necessary for Doppler.
You may program the Baofengs to operate "split" mode but then you're
limiting yourself to semi-duplex operation.

Good thought, David. I do have the settings FCD Centre Frequency set
for 145945. But I also have the auto tune range limited to 34599-44854
kHz which should only let the auto tune catch approximately 145931 to
145941 kHz. So it should not be (nor do I observer it to) tuning any of
the transponder portion. It is always locked on the beacon as
identified by the hump and beep "spikes" as I watch it.
I do not hear FMing on the beacon. It sounds like it should, but it is
covered by a stronger SSB signal, basically. And it appears that the
combined doppler shift of the beacon and the signal make them move
across each other such that the QSO eventually passes by but then
another can come up and do the same.
Overloading the FCD maybe? I do have a preamp on, maybe I'll try it
tonight without the preamp. The reason I use the preamp is that when I
initially set up, I could not get a solid spectrograph (it blinked on
and off) unless I had the preamp on. I believe that was related to the
version of Dashboard I had at that time as observed by a friend who had
seen the same thing when he just got his FCD Pro + the other day, but it
disappeared when he upgraded his Dashboard. Preamp is off now, I will
see what happens this morning and tonight.

I also observed something like this the other day. I wondered about its
cause, but as I was actually doing something else at the time, I
completely forgot about it.
There were, as you note, strong SSB signals around the beacon freq
during the AO-73 pass.
