Hi All Who could remind me of the physical equation that calculate the lift off distance depending on time different between the old and the new AOS (e.g ISS)? Nader. st2nh www.st2nh.com

TS-790 & Chasing Satellites
by William Liporace - WC2L 17 Jan '09

17 Jan '09

Good Afternoon, I think I have my station ready to chase the birds. I have the TS-790, G-5400, PIC Controller and SatPC32 working. I am looking for some help with working the satellites with the TS-790. I do not quite get it. I can setup a time to call some one on a landline. I have had this for a while and have never had it all working. I feel pretty good that I have gotten this far. I would appreciate any help. TNX es 73 Will WC2L

Where can I find the details involved in the process of adjusting the ISS orbit. 73 Bob W7LRD -------------- Original message -------------- From: "David Barber" <david.barber(a)dbelectronics.co.uk> > To follow up on the comments of others and I hope it helps: > > ISS appears to be running just over 4 minutes late (approx 4m 17s) with > respect to the current Keps. > > Measured here on the 20.55utc UK pass. > > David > G8OQW > > _______________________________________________ > Sent via AMSAT-BB(a)amsat.org.

To follow up on the comments of others and I hope it helps: ISS appears to be running just over 4 minutes late (approx 4m 17s) with respect to the current Keps. Measured here on the 20.55utc UK pass. David G8OQW

23cm35ez
by Andrew Glasbrenner 17 Jan '09

I think I have a problem. I'm assembling a 23cm35ez that I picked up second hand. I think I may have a direction set from an older version. Mine has a three piece boom, and the instructions show a 2 piece. Also the number and length of the elements do not match. Since these antennas don't always go from long to short elements, the instructions are pretty important. Does anyone have the most recent version they could email me? I can only find the 8-15-94 revision online. 73, Drew KO4MA

ISS Keplerian elements
by Pierre van Deventer 17 Jan '09

17 Jan '09

Regarding ISS and the accuracy of the predictions. The same was noted yesterday at around 14:00 UTC. AOS was about 2.5 min's late and was able to work via the cross band repeater until it was 5 degrees below the horizon! My Keplerian data and PC clock is up to date, I also suspect that there was an orbit change and the "new" Keplerian data has not been made available yet? 73, Pierre ZS6BB

Thanks to ARISS team
by andy thomas 16 Jan '09

16 Jan '09

Now that we have passed the Jan 15th end of the ARISS commemorative event I'd like to thank the ARISS team for this exciting and educational experience through the ISS repeater, on data, and with other downlinks. I have found it a very stimulating experience, using the various different modes, and indeed reminding me why I bought my IC-910 in the first place, hi! It's sharpened up my act on a number of things including *properly modulating my 9k6 tx with an external Symek TNC *configuring RX with AGWPE and UISS at 9k6 *my best orbit for an antenna without a rotator, set for MaxEl *Choosing FM-narrow on V uplink *using the telebridge via echolink for school contacts *the late update of the keps after an ISS orbit boost and a host of other fine details. It was also very stimulating to have qsos with other amateurs trying to get through the repeater for the first time. Next I have to move to Mode L ... another techie challenge! One day I'll speak to the crew too, as I have done with Mir, in another generation, it seems. thanks again 73 de andy G0SFJ
