We have a new beacon type out at the moment - and it has a message in it! See

STRaND-1 telemetry information

General STRaND-1 information
Yes, 2.4 GHz was very noisy. AMSAT Eagle was to use a 3.4 GHz high-speed
(0.5-1 Mbps) BPSK downlink. BPSK was chosen for maximum efficiency in the
PA. WiFi and WiMAX use complex modulation schemes that are optimized for
terrestrial applications where the signal is diffused and scattered by
Lame telemetry nuts like me that don't write code need a Windows decoder :)

Another satellite comes back to life:

AO-7 isn't as old, but so far as we know, came back first. There is always
the question of how long this latest satellite has been transmitting before
somebody noticed.

LES1 (I think) has a bent-pipe transponder for military UHF (250 MHz
area). I wonder if the billion to one chance that the transponder came on
too?

In terms of noise a 3400-3410 MHz satellite band would have a lot going for it,
unfortunately it isn't a Global

Hi all.
An interesting observation this morning (in CN87) I coppied OH5LK on FO-29
calling CQ in CW at about 1840Z while uplinking to AO-7. FO-29 was out of LK's
footprint at the time. So ground to sat-to sat-to ground was observed. The
downlink of AO-7 is the uplink of FO-29. To complete a
they could take L S band stuff, real dx!

I put the URL into Google language translator and the STRaND-1 TLM Decoder
disappeared, only seems present in the German text version.

Gus and the gang,
What about K5OE's array here:
http://rfanat.ru/s8/P3D_yagi.htm
Still think that using:
8x4 aluminum tube stock
1 aluminum round stock
1 arduino
4 relays
a 24 v ps
some limit switches
fuses, of course
two of the appropriate value pots and maybe some gearing
and a few gears,
The Google translator translated STRaND to Beach !! It's there and
works great!

The control hardware (Arduino based or otherwise) will be the simplest
part of any design. I recently bought all the components to make four
'Uno' (which should be more than capable) for less than $10 each, and I
didn't shop around. No, the hardest part will be the actuators (IOW,
the motors
Gus,
I like your thinking. Simply put we need to make feedback position
sensor with associated motor/motor control stuff.
The motor rpm's and gear ratio are functions of the number of degrees
per unit of time, as you say.
One simple solution that I was going to try was a reversible dc gear
I particularly like the idea of using bicycle gears/chain for gearing.
Whatever we come up with, I'd prefer if the bulk of it was available
locally, wherever you live. There are no Home Depots in my country, but
there are lots of bicycles. Perhaps we can use the frame of the bicycle
to
