I see the BBC has changed it to a "live teleconference link" now so thats a bit better. Here! <http://news.bbc.co.uk/2/hi/uk_news/england/london/7636229.stm> Trevor - any chance of getting the BBC to add more specific websites to the "Related Internet Links" panel to the right of the story?

AO-51 L/U FM operation
by Gould Smith 26 Sep '08

26 Sep '08

There was a problem changing to FM operation on the L uplink to the second repeater on AO-51 last night. That problem was corrected on the 1345Z pass this morning and the second repeater is in mode L/U FM and is now working fine. Enjoy this mode the rest of the week. 73, Gould, WA4SXM for the AO-51 Command Team

ARISS school contact
by David - M0ZLB 25 Sep '08

25 Sep '08

http://news.bbc.co.uk/2/hi/uk_news/england/london/7636229.stm Disappointing to note that the BBC's on line news report of the ISS school contact today with a school in England noted that the contact took place via "satellite phone" doh! Bearing in mind there were three or four TV crews there, it is surprising that they were not given a handout with the facts or that the organisers failed to brief the media properly! A bit of a waste of good publicity for ARISS and the amateur radio service methinks! David KG4ZLB/M0ZLB

AO-51 mode-L/U FM observations
by OZ1MY 25 Sep '08

25 Sep '08

Hi all, AO-51 is working very well in mode-L/U FM. On the two last passes here over Copenhagen [Denmark :-)] The signals on the uplink went through the "transponder" with nice downlink signal. There is some slow fading, QSB, on the uplink when the satellite turns. That can not be avoided - but if you keep talking your signal will come up again. Remember that the downlink on 435.150 MHz is left hand circular. I use an IC-910H with 10 W on 23 cm. Antennas are two 19 turn helixes - gain about 18 dBi, right hand circular. Cable loss like 4 dB to the antennas from the transceiver. Another observation is that it helped to use the compressor in the IC-910. Managed to get a resonable downlink signal when the distance was about 3200 km. Have fun. 73 OZ1MY Ib

FO-29
by Dave Guimont 25 Sep '08

25 Sep '08

Where is everyone on FO-29??? Had a pass in San Diego ~1930z, and found one contact, Jim, W6ASL in Concord CA... It covered Alaska, a big chunk of the US and Canada, and the NE corner of Russia... I used about 50 watts EIRP on the uplink...with some polarity fading at times.... We've got from 145.900 to 146.000 on the uplink, cw or ssb, room for many, many SIMULTANEOUS QSO'S. Why fight the mob on AO-51???... Get Marty Davidoff's SATELLITE EXPERIMENTER'S MANUAL if you need help in understanding the procedure... A fifth grader could do it easily... 73, Dave, WB6LLO dguimon1(a)san.rr.com Disagree: I learn.... Pulling for P3E...

I'll have to agree with Tim. I dusted off my arrow a few days ago and walked outside to work AO-51 and I haven't had any problems at all. I have been consistently working three and four stations a pass using 5-watts or less and my arrow antenna. I remember when it was quite difficult to get into 51 with the same setup. Maybe people have gotten more polite or maybe it's just luck. 73, Eric W4OTN >For what it's worth, guys ... any day can be QRP day. > >I'll soon be applying for the AMSAT Achievement Award using confirmed contacts >that were all made while I was transmitting 50 milliwatts RF out from my Yaesu >VX-7R, on 2 AA Duracells - the same set of AA Duracells, actually.
