08 Jan '10

Good Satellite Afternoon, I will be making a satellite presentation and demonstration on Sunday, January 10th in NY; taking part in Ham Radio University 2010, www.hamradiouniversity.org ,sponsored by the Great South Bay ARC. I will be working the SO-50 pass at 15:09 UTC and the AO-27 pass at 18:50 UTC. on Sunday, 1/10. I will be using the HRU call W2V from FN30, the crowd will be warm, I'm sure, the weather cold. I look forward to a few exchanges, thank you. 73, Pete, WB2OQQ

08 Jan. 2010 HO-68 FM and Digital Transponder 22:35...Turn On North Africa,Europe,North Pole,NA,North Asia,East Asia,North Australia 23:20...Turn Off It is a very good opportunity for me to make transcontinental FM contact. With elevation abt. 2 degree I suspect good link with HO 68 to contact NA. Matt SQ7DQX

RS Satellites update
by Mike Rupprecht 08 Jan '10

08 Jan '10

All, I got some news from Alex, RW3DZ: RS-28 = UGATUSAT (Ufa) - failed due to malfunction of electronics RS-29 = STERKH - ID was reserved for this satellite but they used their own TRX rig and this number was omitted so far RS-30 = Yubileyny-1 RS-31 to RS-37 were used for ORBCOMM satellites under contract from OHB-systems RS-38 = Tatyana-2 is working perfect and operate well under Kaluga control RS-39 = Chibis - is under construction since 2006 and may be in orbit in 2011 RS-40 = Yubileyny-2 - will be in orbit this year next new RS satellites also in progress written by RW3DZ and edited by DK3WN

HO-68 BBS upload!!
by Dave Aitch 08 Jan '10

08 Jan '10

I also uploaded a file with WiSP. Hope you can download it OK. It would be nice if other voice users did not transmit until the packet transmission has stopped though. Patience gentlemen, please. 73, Dave. G1OCN. AMSAT 5766 Subject: [amsat-bb] HO-68 BBS upload!! I succeeded in upload a file into BBS using WiSP, the file number was 'CB'. http://www.ne.jp/asahi/hamradio/je9pel/xw1_digi.htm#bottom JE9PEL, Mineo Wakita

Re: IC 910H query
by DOMINICK INTERDONATO 08 Jan '10

I agree with all you have suggested, Mark. I too had questions about power output on the 910. I discovered that the power to the radio was the culprit. Before you send it away, check and make sure you have #10 cables to the radio and your power supply delivers the correct voltage and current. Mine does and it meets Specs on VHF and UHF on "both" my 910's. One I have the 1.2ghz Module in. One I use for demos at field day and hamfests etc. Good luck. 73, NB2F Dee On Fri, Jan 8, 2010 at 9:18 AM, Mark L. Hammond wrote: > Hi Louis, > > Congratulations on your new IC-910H!

IC 910H query
by Louis House 08 Jan '10

08 Jan '10

I plan to commission my new IC 910 H on Saturday this week. I plan to drive the radio with the "RigTalk" and CIV cable from a USB port. Has anyone experienced any negative function from this data control system type?? In setting up the SatPC32 software, the addresses that appeared by default are "$60" (in all four boxes in the "Radio Set Screen"). Does this $60 setting work OK?? The read me file is not very clear concerning the selection for "RTS + 12V", does the IC 910 H need this setting selected to work correctly?? Any other known problems would also be most helpful. Thanks for listening. Louis, KD5GM CW ;-) The Original Digital

Re: probably simple
by Bob- W7LRD 08 Jan '10

Hi Greg, Drew, etc This conversation is starting to make my head hurt! My example is to connect with some of our European friends. Some of them I share maybe a 60 second window, with PA1TNO it is less than 30 seconds. I have had several false starts in that I heard Paul 2E1EUB, by the time I located my downlink on his, he was gone. I want to predetermine where to set my uplink for a given downlink. There just is no the time be looking around. Like I said this is probably simple I'm just have trouble getting my thinking around the concept. Also if say I am planning on a downlink of 145.950 will Paul be looking at the same frequency? In the past these concepts never concerned me as there was always plenty of time to yak it up with the locals on AO-7. 73 Bob W7LRD CN87 Seattle, Wa. ----- Original Message ----- From: "Andrew Glasbrenner" <glasbrenner(a)mindspring.com> To: "Greg D." <ko6th_greg(a)hotmail.com> Cc: w7lrd(a)comcast.net, amsat-bb(a)amsat.org Sent: Thursday, January 7, 2010 9:30:44 PM GMT -08:00 US/Canada Pacific Subject: Re: [amsat-bb] Re: probably simple > > > But any pass where you are really stretching the footprint is going to > be a low elevation pass.

This is only the case when the two stations are at near right angles to the track of the satellite. Use the following example. If I want to work LU5BOJ/O in FG75 from EL88 on HO-68, my only windows are at either LOS or AOS, depending on whether it is an ascending or descending pass. Neither pass will be a low pass for either station, and neither QSO will occur at TCA or zero Doppler. In Bob's case, let's look at his next possible window with Paul, 2E1EUB in IO92. Bob is in CN76. At the beginning of the 1 minute window tomorrow at 1251Z, Bob's Doppler shift on 432 is -3.68 khz. On the next mutual window at 1452Z, the beginning Doppler is -7.93 khz. On the next, at 2020Z, it's -8.3 khz. None of these windows are over 2 degrees elevation, and none are at TCA for either station. When you have 60s to make the QSO, being right dead on frequency is essential. Respectfully, Drew KO4MA

Hudson Valley Satcom Group Net Tonight 8PM OnEcholink N2EYH-L
by Cotejaune2＠aol.com 07 Jan '10

07 Jan '10

Hope everyone had a great holiday season and found some new radio gear under the Christmas tree. It is time again for our net tonight at 8PM on Echolink N2EYH-L or on the Mt Beacon repeater at 146.970 pl 100 on your dial. We hope to have one or two Amsat area coordinators joining the net to answer any questions you may have. Share satellite your knowledge with us on the net. Hope to hear you there. 73 Gary/wa2aqh
