The spectrum issues faced by moon-bounce (EME) operators are similar to those affecting the Amateur-satellite Service, see this video made by volunteers from the British Amateur Television Club (BATC) http://www.uk.amsat.org/?p=10253 73 Trevor M5AKA

PROITERES
by GW1FKY＠aol.com 10 Sep '12

10 Sep '12

Hi all, After 7 weeks of operating our Flagship Olympic and Paralympic event station 2O12W ( Two Oscar One Two Whisky ). We made over 17.000 contacts and in the early stages I was able to dedicate some time to satellite contacts (over 40 ) and included the USA and Canada . The contacts were mainly via FO-29 and VO-52 Alas I was unable to give my time to the better passes of AO-7 sorry to say. Due to local QRM I was also unable to make a contact with Cuba which I had a request for. Thanks to all for your support and patience with the contacts both on satellite and HF with this perhaps once in life opportunity of an Olympic Flagship in Wales. The flame has gone out but the throat will be burning for a bit longer Hi! Hi! Having caught up with the news I listened for "PROITERES" this morning from my home QTH and was able to hear the satellite quite well with just my usual "ELK" antenna. "Congratulations to the team and all concerned " Ken Eaton GW1FKY Amsat-UK Amsat NA

ISRO's 100th Mission
by Mani VU2WMY 10 Sep '12

10 Sep '12

The Japanese amateur radio satellite PROITERES will be one of the payloads of today's PSLV C21 launch and will be the 100th mission of ISRO. PROITERES was built by a team of students and faculty members of Osaka Institute of Technology (OIT) and the spacecraft aims to demonstrate powered flight using a Pulsed Plasma Thruster (PPT) engine. Its amateur radio callsign is JL3YZK. PROITERES stands for PRoject of OIT Electric-Rocket-Engine Onboard Small Space Ship and will transmit on 437.485 MHz FM/AFSK. The spacecraft carries a camera and the two CPU’s run the Linux operating system. www.uk.amsat.org/10201 Mani, VU2WMY Secretary & Station-In-Charge Upagrah Amateur Radio Club VU2URC ISRO Satellite Centre HAL Airport Road, Bangalore-560 017.

Thanks for the NOVA and Camera advice!
by James Luhn 09 Sep '12

09 Sep '12

Thank you to all who helped me with NOVA. I really feel dumb about my mistake of not looking up the REAL name of a satellite. I appreciate no one mentioning my ignorance. Thank you to all who commented on my camera on a beam. I forgot about the need for a telephoto lens. I also was not thinking about the advantage of the az-el rotator with respect to looking around the neighborhood(thanks Bob!). If I could get the correct keps, maybe I could even follow movement. Don't be surprised if I post some unusual photos instead of the green cheese on the moon. I have been a Ham for over 50 years and I am still trying to figure all of this stuff out. Working satellites has been my highlight of my 50+ years. This is one helluva great hobby! Thanks Everyone, 73 -james W5AOO
