Hi Dan,
Here is my proposed paper:
Software Radio Technology on SuitSat-2
SuitSat-2 will be the first amateur satellite in orbit to rely on
software radio technology. All of the radio signals will be generated
via digital signal processing software including a CW beacon, an FM
audio signal, a BPSK beacon, and a linear transponder. This paper
provides an overview of the radio system and digital signal
processing software developed for SuitSat-2.
73,
Tony AA2TX

Here's a snippet from March 6, 1988 at 2039 UTC, 145.830 MHz up, 29.453 MHz
down:
http://www.qsl.net/kd2bd/rs11-robot.mp3
I was keying an FM rig to produce the uplink.
The downlink was received using a converted Hy-Gain CB board (used for 10-
meter FM operation in previous years) in concert with a 455 kHz ceramic
resonator as a narrowband IF filter.

I wonder if some AMSAT VIP's in the DC area should go to this:
*Coffee Briefing on Space Debris and Collisions*
*Wednesday, June 10, 2009*
*9:00am - 10:00am*
*2253 Rayburn*
*Keeping Our Space Assets Safe From
*an Increasingly Crowded Space Environment,
If I was in DC, I would go to represent Student Satellites, but I am in
Alabama on travel. Our position should fully support the mitigation of space
debris, but we must make sure that the regulations are not overly burdensome
to the small guys.
I reviewed a first draft that was ONLY written for the 100 Million dollar
Launch Provider. It placed an extrordinary burden of "tests" and "reports"
and bureaucratic processes that of course would be routine for the Space
COmpany with an army of lawyers in their employ, but there was no provision
for the small 1kg student payload for a simpler process.
This meeting is not the place to speak up, but it is the place to learn and to
circulate and network and get a copy of what is being considered.
Im far from my desk and so have none of my AMSAT contact info, to try to get
this to the AMSAT folks that might be able to get to the meeting.
Maybe one of them will see it here and can see about an amsat presence?
Bob, WB4APR

Thanks Bob, I forwarded it to the bod@xxxxx.xxx list, as well as the
officers list.

Hi Dan,
I will be submitting a paper entitled:
"A Linear U/v Transponder for SuitSat2"
Abstract:
SuitSat2 will incorporate several advanced circuit functions which will
be directly applicable to the "modular" development program under way at
AMSAT-NA. One of the SuitSat2 modules, the linear U/v RF transponder,
uses the latest in solid state device technology to provide a very
efficient 1/2 watt 145 MHz transmitter and a low noise 435 MHz to 10.7
MHz down converter. The design philosophy and circuit details will be
presented.
Regards...Bill - N6GHz

Hi Bill,
Excellent!
Looks like we will have the whole RF system covered.

Hello.
Am looking for information about vertical dual band (144/430
mhz) antenna
to work some LEO satellites.
Something like a 6/8 (144) and 3x5/8 (430) like X-50 from
Diamond
or 1/4 (144) and 2x5/8 (430) like X-30 also from Diamond.
Or somthing like that.
Thanks in advance.
Juan Carlos, CO8TW.

Hello Juan,
Do not expect much from a vertical antena for sattelite, I had made some few
QSO via ISS only and could not listen well other sattelites.
But if you really want to try I can suggest the Dualband COMET GP-9N 3x5/8
wave lenght antena.
8,5db gain VHF and 12dbi gain UHF. Is a very good antenna, good quality
and low SWR.
Better you choose twice Eggbeaters V and U for sattelites.
