Re: Redundant geostaionary birds?
by Dave hartzell 30 Jan '07

30 Jan '07

It looks like the commonly adopted block conversion for C-band transponders wouldn't land in our bands. There seems to be a delta for 2.2 GHz for the block conversion (e.g. 5.9 GHz up, 3.7 GHz down). We'd need more like a 4 GHz conversion to land in our S-band, given a 5.8 GHz uplink. I'm sure the filters aren't quite tuned to go below out of band, either. Another issue I just realized is that these transponders use polarized signals (left, right, vertical, horizontal, polka-dotted)....this again makes using an old communications sat a bit more difficult (but not impossible) for us hams. Looks like this was not meant to be! 73, Dave NøTGD On 1/28/07, Karl Bullock <karl(a)bullock.org> wrote: > > Dave hartzell wrote: > > 3) Most of the uplink freq's are in the 5.9 GHz range (out of our > > allocation) and downlink in the 3.7 GHz range, again, (out of our > > allocation). > > > That may be _the_ problem.

My first Posit via PCSAT for a long time
by Robert Bruninga 29 Jan '07

29 Jan '07

> On Behalf Of Mike Zwingl oe3mzc > I will be travelling V51 NAMBIA during June, JULY, AUGUST > and want to know if it would make sense to use any of the > PACSATs for APRS out in the bush, like I did with ISS in > West Australia last year? It is the chicken-Egg problem. I hope that we can inspire other satellite builders to support this simple wilderness/mobile position and status reporting application. We hope others would build PCSAT (APRS) compatible digital satelites on 145.825 to continue this viable moble satetllite application. We figured there could be as many as 6 or more such satellits all on 145.825 to provide almost continuous coverage for travelers. But PCSAT-1 only works during mid-day passes when it is in the sun. And this is so spotty, that it is hard to keep the worldwide network of ground stations interested. But for the next several months, and in the future, we will have these satellites on 145.825: PCSAT-1 - sometimes workable during mid day sun ANDE-1 - through June 08 but needs wakeup every orbit RAFT - RX only works at night and is very weak PEHUENSAT - has no user uplink FASTRAC - FUTURE U of TX Satellite with links on 145.825 ECHO AO51 - Digipeats 9600 baud but is on different freqs and we do not have enough Igates for the downlink But the key is keeping enough ground stations IGATING all the packets they hear on 145.825 to make this system work.
