There's allegedly one in the Nov Silicon Chip.

Only 1200bps sinngle duplex though 8-(

What the fuck is 'sinngle duplex'

Presumably you mean half duplex and not simplex.

Hi Ken

Not sure what's up with my brain lately - that should indeed have been
"PSK", not "QAM". Sorry.

No problem - if I had a penny for every time I had a minor aberration...

PSK's used quite a bit still.

You're certainly right about efficiency with the class-C and all that - I
hadn't thought of the microsatellite application. I deal with bigger birds
but with the general limitation of restricted bandwidth. Horses for
courses,
which I think we can safely assume we both knew but didn't think of
off-hand.

I see you're (probably) in UK - are you at Surrey? Are you actually
working
in uSatellites??

You're getting very warm! I have more than a passing interest in the SSTL
satellites amoung others. I have a few meetings a year over there at
Guildford with some of the folks there including the infamous Martin
Sweeting, arguably the father of the microsat, a couple in Europe regarding
the International Space Station plus two in the US too, which keeps me out
of trouble. Most of my technical interest lies in the grounstation hardware
rather than the satellite itself, although I do run the European command
station for two LEO satellites.

Kind Regards, Howard
http://www.g6lvb.com might give the game away!

Half duplex is what I meant. Posting before the 1st coffee of the day.

you can use RFpic solutions,which transmit with
ASK or FSK modulation technic.
