Glen, Actually, AO-7 was placed in the narrow-band (CW/SSB) subband back when it was launched. AS I recall a waiver was sought to do this. So AO-7 is, in fact, in the wrong frequency allocation for satellite operations. Perhaps Tom Clark or one of the other old hands that were involved when AO-7 was built/launched can better state this (I was a member of sbms that built the 2.3 GHz transponder that was never allowed activation). As far as attracting new satellite operators, there is an even chance since the operator already is in possession of CW/SSB equipment that is required for AO-7. Basically, they would need proper antennas and learning about tracking issues (times, freq. Doppler, etc.). Also that the input is inverted so one tranmits LSB to hear USB. Most of the weak-signal group (CW/SSB) are pretty savy bunch, so it remains whether it would interest them. 73, Ed - KL7UW Original Message: ----------------- From: Glen Zook gzook(a)yahoo.com Date: Thu, 17 Sep 2009 08:25:11 -0700 (PDT) To: amsat-bb(a)amsat.org, sparkycivic(a)shaw.ca Subject: [amsat-bb] Re: accidental satellite ops The primary problem is that the OSCAR VII inputs are now in the weak signal portions of the "band plans". With the proliferation of FM activity the weak signal portions have been compressed. It is unrealistic to even think of "blaming" the weak signal operators for interfering with OSCAR VII operations. Remember, OSCAR VII is 35 years old and was not expected to be in service for more than just a few years. One should just be happy that OSCAR VII is still usable and work around the occasional situation with unintentional interference. Besides, there are not that many contests on the VHF and UHF bands and most of the time there is little activity in the weak signal portions of 2-meters and 70 cm. As for garnering additional satellite operators that is definitely a possibility. However, I don't know how many new operators would actually be recruited.

OK got it recorded this time. Not as strong as last pass though. AOS @ 10.46utc LOS @ 10.59utc Centre frequency 435.365MHz Initial signal carrier only with short breaks then at 10.50utc cw blocks of alpha numerics until end of pass.

thank you for the info, that is same information i found on there site listed "first set", Satpc32 claimes when i loaded the keps and looked for the nexted few days passes, that it will be hight 312.7 to 309.6 mi just higher than ISS, but cover most of the us on a center us pass?? space track has that number 35870 as a fregit/isrs?? just trying to learn how things go, intersting Rodney kc0zhf

From another list... 73, Drew KO4MA -------- Original Message -------- Subject: [Hearsat] Universitetsky 2 (Tatiana 2) heard Date: Thu, 17 Sep 2009 21:54:47 +0200 From: nils(a)vonstorch.de To: <hearsat(a)mailman.qth.net> Hi all, today a Multi Carrier rocket was launched from Baikonur carrying a few satellites, including Tatiana 2(Universitetsky 2) and Sumbandila into orbit. Found Universitetsky 2 (Tatiana 2) transmitting Data (and occassinally CW also) on ~435,365 MHz. this evening at around 19:20 UTC. Signal was quite strong but with some heavy fading now and then, probably caused by the satellites rotation.

D-Star in the Netherlands
by Gaston BERTELS 18 Sep '09

18 Sep '09

D-Star frequencies in the Netherlands. Abraham van den Berg, PB0AOK - VERON's VHF manager, clarified the D-Star issue in the Netherlands. VERON is the Dutch IARU society. It is untrue that the Dutch administration is thinking about D-Star repeaters operating in the 437-438 MHz band. Presently, the amateur service in the Netherlands and neighbouring countries suffers from harmful interference, caused by what can be seen as a regrettable implementation of the Radiolocation service in the 438-440 MHz band. For that reason, usage of D-Star repeaters with output frequencies in the upper 2 MHz part of the Region 1 70cm band, is hampered. To solve this problem, recently the Dutch D-Star community came up with a proposal to plan the output frequencies of D-Star repeaters just below 438MHz and has asked VERON to support this proposal. VERON has decided not to do so, due to incompatibility between the amateur service and amateur-satellite service. Moreover, the proposal deviates significantly from the IARU-R1 band plan. In the meantime VERON has made an alternative proposition to amend the Dutch national frequency plan in such a way, that it fully complies with article 5 RR, the European Common Allocation table, as well as the IARU-R1 band plan. Thank you Bram, for this clarification. Gaston Bertels - ON4WF IARU Region 1 ARSPEX WG chairman

When I was at MGU (Moscow state university) in May this year I heard that because of the controversy over the use in the Amateur band of the multiplex system Doka on Yubileiny, they had decided not to use an amateur band on this bird. Doka is a system used by Russian universities, originating from engineers in Kaluga. Instead they would use the scientific/educational band at 1.7 GHz, near the HRPT band, and installed a small dish on the roof of the high-energy physics building for that purpose (I have stood next to it). The location cannot see low elevations because of nearby high buildings. Therefore I don't think Tatiana 2 has a 435 MHz beacon but i am checking with friends in Moscow. 73 de andy G0SFJ

RS series mode A downlink power
by Andrew Glasbrenner 18 Sep '09

18 Sep '09

Anyone with any firm data on the downlink power from RS10-13 on 29MHz? A cursory reference check and Google didn't turn anything up. I'm thinking maybe this was a telemetered value and someone remembers? 73, Drew KO4MA

Thanks to the several of you that helped make my demonstration tonight a success. Signals were great on the QRP repeater, and the JARS club enjoyed hearing all of you (from Vermont, to Georgia to Tennesse to Kansas!). I had a "scribe" and I think her writing says: WA4SCA KB1RVT KB0RZD N3TL AA5UK KB1PVH KD8CAO I think that's the list..If you need a card, let me know. 73, -- Mark L. Hammond [N8MH]
