Hello dears freinds :
I write to you to ask for a big favor. I own an old YAESU FT-747 which final
RF
power transistors 2SC2290 or 2SC3240 were damaged.
I have not been able to find them, allthough I have searched ansiously.

Hi Erich,
Thanks for the great upgrade. I see you incorporated the CW-N mode and
the display of the DOPPLER.sqf line in the CAT menu I suggested :)
You are correct, one of the issues with fast changes in Doppler on a
CW-N signal is that it jumps in pitch a lot. I enabled the x5 and x10 mode
and I

I have uploaded two AO-51 audio files to my webserver.
The first is the 12Nov2009 2241Z pass with AA5CK/P

Tim, Sawson and I frequently have such contacts on AO51, SO50 and AO27, and we
would invite anyone with a duplex handheld like our D7s, and elks, arrows and
even AR800s to give it a try. The high passes are the easiest, but folks would
be surprised how well 50 mw radiates through space at most

SO-67 is only turned on occasionally for testing at this point. The
schedule is posted on their web site, sometimes with very short notice:

I haven't heard any activity on SO-67 since the mode vu repeater was on last
weekend. Is the satellite in a different mode? If so what is the downlink
frequency of the beacon? Any information would be appreciated.

My apologies to everyone for this re-post. Actually, it was my original attempt
at posting this. I sent it right after the pass yesterday. When it didn't show
up by this morning, I re-sent the post everyone saw several hours ago. I didn't
think this one was going to make it.
Sorry for the repea

Geeze, I am holding AO-51 schematics in my hand ... and at the last
AMSAT-NA convention, the proceedings book has a ton of info ...
I think the info IS out there. AMSAT-NA doesn't seem to be hiding
anything.

Unfortunately, ITAR is federal law in this country so U.S. residents must

Hi Robin,
You apparently don't realize that almost all recent AMSAT-NA designs are
already open sourced and are available on the internet (such as
SuitSat/ARISSAT) or through the AMSAT-NA Journal, the Proceedings and
other publications. You just need to do a little searching.

I am telling maybe something controversial to you guys but I think
it's this idea is needed for amsat.
The post is made because I had a question to amsat and the satellite
users, builders, controllers,... Why aren't the schematics of AO-7,
AO-51, SO-50,... not posted on the internet?

Hello everyone. The net will not be available tonight on Echolink I was
told by our club

due to Thanksgiving. The next net will be on December 10. If you are able

Tim, Sawson,
Congratulations on your "flee power" contact! Once again experience,
knowledge, patience and the cooperation of good satellite operators triumphs
over power. We should tip our microphones to Tim, N3TL and Sawson (KG6NUB)
for their efforts. I can hear the hiss of rigs being turned on

The ITAR-rules is one of the biggest carp ever.
The solution is to MAKE EVERYTHING OPEN SOURCE:
Make a website where every amateur can download the schematics, pcbs
layouts, software,... This will be a great help.
Make your designs more open. Every amateur will benefit from this action.
