I tried a few obvious names in the Space-Track lookup, but couldn't find orbital parameters for the Jules Verne ATV. What is it called? TIA, -- Rick

Very much appreciated.

Drew, Thanks for your prompt answer to my queries. That's precisely why I asked ... so as not get get up anyone's nose. Actually, I can't work PSCAT or GO-32. As I mentioned, I'm totally blocked by mountains for the ISS (so that rules out PCSAT too) at 1200bps and the IC-E91 would be impossible !! to modify for 9600bps operation, even though MixW would generate it. I believe one needs to "go in" somewhere near the varactor nodulator for 9600bps and for an IC-E91 that would entail micro-surgery ... when ICOM say "low speed digital communications" I believe they mean about 25 bps a day! into the data connector. I find I can't get into AO-51 (portable) with low power and an Arrow aerial due to the alligators - people calling a station that is actually still speaking ... (on FM !!) ... is typical of the AO-51 operating I've been monitoring ... in other words, sending all the wrong signals to the potential newcomer. There have been "reams" written on this subject but the age-old technique of an inadequate receive system ensures the punter turns up the wick to compensate - and cocks it up for everybody ... seems to be the order of the day on AO-51. Thanks anyway Drew - guess I'll just have to take up stamp collecting instead. 73 John. <la2qaa(a)amsat.org>

Its a poor question. Both B and C are correct if you make some assumptions that they are talking about a linear satellite. B is what causes C... > E2A08 What is the primary reason for satellite > users to limit their transmit ERP? > A. For RF exposure safety > B.

Grateful thanks.

My grateful thanks to everyone who took the trouble to reply to my queries about AO-16. Of course !! ... I'd forgotten for a moment that AO-16 is now an FM single-user satellite and therefore pretty useless for low power operation due to the alligators ... so I would have been totally wiped out anyway if I 'd have tried to use APRS or CW. I'm still very grateful for the feedback though ... thank you all. I was trying to find a "satellite" use for an IC-E91 D-Star handheld where there are no D-Star repeaters and I'm totally blocked for the ISS (1200bps packet and APRS) and when ICOM say "low speed data" on the E-91 they probably mean something like about 200 bps a day !!... (???) ...into the 'data' socket. I SERIOUSLY !!!! doubt it's 9600bps capable ???. I am in range of GO-32 but don't have a 9600bps capable radio. I have MixW to generate 9600 but I believe one needs to "go in" at the varactor modulator on the transmitter and that would require micro-surgery on an IC-E91 ... even if a circuit diagram was available - which it isn't ... ... but ... there's always stamp collecting !!. Thanks again, one and all. 73 John. <la2qaa(a)amsat.org>

2 for the group.

Hi All, I am *NOT* a digital Ham - in fact, those that know me are aware that I'm THICKER than the two proverbial short planks so I hope someone with a bit more brain capacity than I have will help me. I have two questions for the group. Question 1. Is there ant reason why I can't transmit a modulated carrier (FM) on the 145.900Mhz uplink of AO-16 and receive CW on the SSB/CW? downlink of 437.026Mhz ??. Question 2. I am 'TOTALLY' blocked by mountains re: the ISS and PCSAT and do *NOT* have 9600bps gear for AO-51 ... however, I can receive AO-16. Can I use the UPW - (PSK modulation) - program to transmit APRS data on the uplink and will that be received on the USB downlink ?? ... and be forwarded to the internet via an APRS station ??. I have attached the UPW file for perusal by anybody who has a few more braincells than LA2QAA and is able to advise. (There are currently no "normal" 1200bps sats - I am trying to find a 'satellite' use for an IC-E91 D-Star transceiver ... no D-Star repeaters in Norway ... as mentioned, I'm totally blocked by mountains re: the ISS). I would be very grateful for any advice and/or (sensible) suggestions please. 73 John. <la2qaa(a)amsat.org>

SatPc32 and ISS with FT-847
by David Julian 09 Mar '08

09 Mar '08

I'm having trouble using SatPc32 for ISS contacts with an Ft-847. When attempting to transmit I receive an Error message on the FT-847. Apparently it does not like being in SAT mode with both VFO's on the same band. Is there a set-up in SatPC that will allow the rig to track doppler without setting the radio in the SAT mode?
