Re: A0 40 replacement

Hi AMSATs, Commercial satellites were very expensive... but we hams find a way to get our own satellite, for much cheaper price. Launches are very expensive now... but maybe there is a way we can do it cheaper ourselves (or with help from rocketeers) ? (Ofcourse not aiming for AO40 size... maybe starting with pico-sat first.. and use rocket body as antenna to save on that...). Just some idea 73 de PE1RAH, William

Re: IARU coordinated frequencies for LitSat-1

Did anyone else notice that the transponder downlink frequency is exactly on the center frequency of FO-29's uplink or that the Packet downlink was on the SO-50 uplink (without the 67Hz tone)?? Seems like this wasn't very well 'coordin ated'. I hope those freq's were misprints.

I've just received two handsome signed photocardss from Cosmonaut Roman Romanenko via Tsniimash to commemmorate the Shadow Beacon experiment early this year! They're on the front of my website. Many thanks to Valentin and friends on the Experiment! andy G0SFJ http://www.andythomas.eu

Re: Ham TV

Thanks Gaston, I am glad that testing is progressing and succesful. For the actual commisioning and ISS testing it would be very helpful if signals from the ISS are not just limted to the European window but test signals are also transmitted across NA. We have a number of folks getting stations ready in the US and Canada. I hope that this option can be discussed with ESA, NASA ISS operation. 73, Stefan, VE4NSA On Wed, Sep 11, 2013 at 5:52 AM, Gaston BERTELS <gaston.bertels(a)skynet.be>wrote: > HamTV Bulletin 2 - September 10, 2013 > > Ham Video - EST and Simulations > > Ham Video Commissioning preparation is progressing.
