Hi AMSATs,
I like to share with you some news about my succesfull experiments with my tinny transponder. I managed it to work with 23cm as input frequency :) The changes are minor, just a few components to be changed and the input filter needs to be changed. I have to do some more testing but all looks very well for having an mode-LU linear transponder.
I just heared about another launch with several "beep"-sats on it. When checking the Satellite Status List on the AMSAT-NA website, you need to search very well to find any satellite which has an uplink frequency. As active AMSAT operator I already deleted most of the kepler lines in the kepler list, as these are all "beep" sats which I can not use.
Lucky thing is that I not have much time to be active on satellites, but every once in a while when I check the satellite list my face gets more and more :( In the past we had a few satellites, but they were very usefull (to AMSAT hams)... Now we have many satellites, but only few are usefull (to AMSAT hams)...
Now up to my next project... a credit-card size Mode-B FM transponder :o)

Hello William,
Nice to hear you are making progress with your transponder. About the "beep-sats", I don't even try to listen to them. There are several new cubesats in space but only with telemetry downlink. I have more fun with sats that has a transponder on board to make some contacts. But that's my opinion :-) 73, Eric -- ON4HF
