Yes, I'm familiar with this. I will ask users to put this notch in the
center of the transponder band (145.938 MHz) so that the BPSK-1000
beacon will appear at about -18 kHz. 0 Hz will correspond to the notch,
the transponder will appear between -16 kHz to 0 Hz and the FM signals
(voice, sstv) will appear in the positive frequencies centered at +12 kHz.
It will be easier if Doppler is *not* corrected for so I can do that in
software. This will move the notch +/- 3.3 kHz around the center of the
passband, and that might interfere a little with the top of the
transponder passband between AOS and closest approach.
If for some reason the I/Q channels are swapped or there's a polarity
inversion simply flipping the sign on the frequency should take care of
it. The BPSK-1000 signal is symmetric so it can tolerate sideband
inversion. (USB reception on a conventional SSB receiver is recommended
only because the CW beacon is 1 kHz below the BPSK-1000 beacon. This
puts the CW beacon at an audio frequency of 500 Hz when the BPSK-1000
suppressed carrier is at its nominal 1500 Hz. It could be received just
fine in LSB mode but then the CW beacon would have to be tuned to an
uncomfortably high pitch of 2.5 kHz, and it would be harder to tune it
accurately by ear.)

Much to my amazement, during prelaunch testing I was able to decode
BPSK-1000 that had been run through lossy codecs like MP3. But I don't
recommend it. If the recording data rate is a problem, reduce the
sampling rate while ensuring that the 2 kHz wide BPSK-1000 signal is
completely captured within the Nyquist bandwidth of your A/D converter.
E.g., 8000 or 9600 Hz should be fine provided the BPSK-1000 signal is
centered at 1500 Hz. Although the demodulator assumes an A/D sampling
rate of 48 kHz, a recording with a lower sampling rate can be converted
back to 48 kHz with a program like 'sox' as long as the information is
still there.

Hi all,
This Saturday the 20th of August I am planning on heading to the grid line
of en22 and en21. I am going to try and be on all passes of SO-50, AO-51,
AO-27, and FO29 between 1800z and 2200z. I don't know if I will be able to
bring enough equipment to operate FO-29 yet. The main goal of my trip west
is to help my sister move into her apartment for college so nothing is set
in stone.
If we make contact and you need a Qsl cards just sent me a email and the qso
information and i will get a card to you as soon as possible.
Also if anyone needs a qsl cards for my brief stay in en53 and when i was
mobile in en42 just send me a email of the qso info and i will get a card out.

You don't have to use a narrow beam antenna with maximum gain on axis.
You can always design it with a bowl-shaped pattern that increases gain
toward the edges and lowers it in the middle.
The GPS L-band transmitting antennas are a good example; even at their
much higher altitudes, the earth appears fairly large and a simple lobe
would provide uneven illumination across the earth.
A stabilized satellite pointing an antenna at a fixed angle to the local
vertical would eliminate the deep, slow, periodic fading that we see at
present due to constant changes in polarization and/or the antenna lobes
sweeping past earth. Without these fades, coherent demodulation would be
practical, picking up several dB of performance even before you consider
the considerable increase in average signal strength. On a microwave
band with sufficient bandwidth, efficient coding would make possible
much higher user data rates and/or operate with considerably less DC
power. Data rates of several megabits/sec would be entirely practical
from a small satellite to a small dish on the ground. That means HDTV in
near real time, or a steady stream of high resolution still photographs.

As far as I know, and this is *NOT* the official word, the correct
antenna was installed but the external section of the element was broken
off. There's about 1.5" of antenna blade embedded in the epoxy, which is
why the antenna still hears pretty well. Reports of users getting into
the transponder with as little as 1W prove it can't be the dummy load.

Hmmh, interesting. The 02:30z pass this evening over CM98 sounded like
normal low power mode. Female announcement, switched to foreign language
(sounded German), SSTV picture (canned), few minutes of silence, then more
talking, then silence to LOS. No voice telemetry, and I'm not set up to
record the digital stuff.
This was a directly overhead pass (on the correct side of vertical for a
change!). Next pass is in 27 minutes, 15 degrees up to the North West (my
good horizon shot). Will report back what I hear.

Yes, and the fact that none of these piggyback payloads have ever come
to fruition, while we do continue to get the occasional ad-hoc small
satellite deployment opportunity, suggests that we need our own attitude
determination and control system if at all possible.

As everybody knows, even tiny errors in the Keplerian mean motion (MM)
will accumulate over time and put the satellite ahead of or behind where
it really is. That will show up as a large frequency error when Doppler
is changing rapidly at closest approach, but a small (or no) error near
AOS and LOS when Doppler isn't changing rapidly anyway.
So instead of manually tuning the radio to compensate for unpredicted
Doppler, why not manually tune the element set? I recommend manually
adjusting the "mean anomaly (MA) at epoch" until the satellite is on
frequency. This parameter says where the satellite is within its orbit
relative to perigee at the epoch time, so changing it slides the
satellite forward and backward along its orbit. If this is indeed the
main error in the element set, then correcting it should cause the
satellite to track normally even through closest approach.
This has the added advantage of correcting your antenna pointing as well
as your radio tuning.
This is probably better than tuning the mean motion (MM) as it would be
difficult to distinguish between the two during a single pass. The MM is
the time derivative of MA, so the effect on orbital position from a
given change in MM depends on how long it's been since the epoch; the
older the eleset, the greater the resulting change in position from a
given change in MM. A given change to MA always moves the satellite by
the same amount regardless of how long it's been since the epoch.
Properly adjusting the MM separately from the MA would require careful
Doppler measurements of a number of orbits.

Hi Gould,
Ok, 04:01z pass over CM98 in Northern Calif... Max elevation 15.6 degrees,
to the North North West.
Pass started with a foreign voice (Russian, I think). Then there was a USA
welcome message (with the USA Secret Word), and an SSTV image. Not sure
which one, as there was too much noise anx suitsat2@xxxx.xxx

I listened during part of the same pass here in DO33. Due to ARISSat's
position and my location, I wasn't able to hear more than a few seconds of
the transmission. It was up to S8 on my radio's S meter but it was noisy
for much of it.
I heard part of the children's segment followed by a few seconds of open
carrier andsome
time back, and the "beam width" is about 140 degrees....
Point them straight up and be satisfied with that part of a pass, or
mount them at 40 degrees, and rotate AZ with a TV rotor for the
entire pass. For 50 degree max passes point them at the center of the pass...

Yes, something with that kind of beamwidth would be ideal on the
nadir-facing surface of a stabilized satellite in low earth orbit. It
would be even better if the gain in the straight-down direction could be
reduced in favor of gain at the edges. Ideally you'd have a constant
power density over the entire visible earth.
You could of course use a much more directional antenna on the ground if
it can track the satellite.

Do we know which callsigns were sent out over CW? There's a limited set
of 32 CW Ids that are sent when the SD card is not available. Also, did
we get any of the stock SSTV images?
Are we still seeing this? I pulled the one of the latest STP files
(201108182126711), and it's indicating that call signs are being sent
from the SD card currently, and the MET is 1h 7s.
I didn't instrument the FM mission enough to be able to tell from the
telemetry stream if it's getting more from the SD card or not,
unfortunately.
