Hi All, my problem is solved, now I can work satellites again,
I am active from now on EK19 at:
Hola a todos,mi problema fue solucionado, ahora puedo trabajar sat?lites
nuevamente
sin problemas, desde ahora estoy activo desde ek19, prometo regresar a ek18

It looks like a plain old HD44780 16x2 LCD. You could use *anything*.
Digi-key are scandalously expensive for them. Try eBay.

Cubesat HF experiment:
We have revised our HF satellite experiment proposal to be a CW telemetry
beacon on 40, 20, 15 and 10 meter bands. The experiment will last only a
few days, since the deployed 1000m tether will have so much drag, we will
de-orbit in only a few days.
The idea is a keyed CW oscillator on 7.010 MHz with harmonics on 14.020,
21.030 and 28.040 MHz. These bands are all in the IARU Satelilte
allocation. We will filter all harmonics above 28 MHz.
The challenge will be how to feed a 1000m long wire from only a 4"x4"x7"
counterpoise (on all bands). transformer coupling?
The tether will be vertical and can act as a long wire antenna with a very
narrow cone angle pointed straight down. Antenna gain will be more than 10
dB on all bands. This moving donut gain pattern sweeping across the earth
should pose some interesting reception reports (If any of it gets through
the ionosphere).
Launch Opportunity no earlier than March 2012. Putting us closer and closer
to the Solar Max which would be the worst time for this experiment.
Other than a nice AMSAT experiment, if anyone can use this for valid
ionosphereic science, come join us.

Hi Bob,
Congratulations, sounds like an interesting experiment.
I will be listening for the transmissions.
Do you have estimated output power yet?
Will the cubesat TX in eclipse, less active ionoshere.
Will the beacon be on all the time, or intermittent.

Mark,
While I really like the audio on S-band a lot better than U, I think 9600 b
packet is a great idea! I know you meant it tongue-in-cheek, but if a real
emergency occurred world-wide (you know, like we lost the Internet during
the upcoming royal wedding or some other equally cataclysmic event),
store-and-forward technology would be a viable and reliable way for hams
without HF privileges to communicate world-wide. Reminds me a little of
Independence Day :-)
73,
Jerry, K5OE

Hi Bob,
I think it's safe to say that we won't be running S-band. We haven't planned
that far ahead, but I expect we'll be in mode V/U simply because of eclipses
and the battery.
Or we could run 9600 baud packet instead :)
73,
Mark N8MH
