Hello Group, I listed some satellite related items on Ebay tonight, and will try to list more tomorrow. My Ebay ID is ko4ma, and you can go to this auction, then see all of them at the "View Seller's Other Items" link: http://cgi.ebay.com/Kenwood-TR-851-432-435-ssb-satellite-AMSAT-UHF-all-mode… I'll donate 10% of the auctions to AMSAT in return for the bandwidth on -bb! 73, Drew KO4MA

Re: AO-51 back in mode J-FM (and VERY busy)
by DOBarrows＠aol.com 05 Sep '06

05 Sep '06

W8EH observes: Part of the trouble that I observed with AO-51 is some stronger stations (without PL) or illegal cordless phones, are blanking out the uplink. I had trouble after the switch to V/U. I usually run 2 watts to a CP KLM beam. Even with the rig boosted up to 45 watts, I couldn't overcome whatever/whoever was blanking out the sat most of the time. Out of two passes this morning, I made only one contact. Lots of stations on, but only the strongest seemed to make it over whatever was blocking us. Strange that I didn't have that trouble at all when it was in V/S mode earlier. =========================================================== I noticed the same thing - it was like AO51 had the squelch set too high. I would hear stations call me and when I keyed the mic to answer I couldn't hear myself in the downlink. It seems to happen more when AO51 is at a high elevation, maybe because the offending non-pl tone station is in my part of the country or maybe it is just that my transmit antenna (KB6KQ loop) works best at lower angles. Don't notice it on SO50. -- Dave W8IJ

OT: Ham radio stores near Moscone Centre ?
by Tim Tuck 05 Sep '06

05 Sep '06

Hi all, Sorry for the off topic post but I'll be in San Francisco attending a conference at the Moscone Centre first week of Oct, and I was wondering what Amateur Radio stores are within walking distance of the Centre since I'm staying at a hotel close by ? This will be my first trip to SF so I hope I wont get lost :) Any other AR related info about SF greatly appreciated ! cheers Tim -- VK2XTT :: BMARC :: WIA :: AMSAT :: QF56if

Trevor, Can you clarify what all of these are? The 1541.200 MHz seems to be in the 1535 to 1545 MHz range that you specify elsewhere as a TAL site pre-launch briefing on INMARSAT. 73 de Félim M3HIM IO91ot Aylesbury, Buckinghamshire, UK ----- Original Message ----- From: "Trevor" <m5aka(a)yahoo.co.uk> To: "AMSAT BB" <amsat-bb(a)AMSAT.ORG> Sent: Wednesday, July 05, 2006 8:29 PM Subject: Re: [amsat-bb] STS-121 > --- Vincenzo Mone <vimone(a)alice.it> wrote: > > > Hi to the list, > > pleas which are the up/downlink frequencies for the STS-121? > > I understand these frequencies are used for launch related comms: > > 1541.200 MHz, 1435.5 MHz, 261.875 MHz (f.m.) and 10.780MHz (u.s.b.) > > 73 Trevor M5AKA > > > > > > > ___________________________________________________________ > All new Yahoo!

ISS Voice, Packet & SSTV FM deviation
by Félim Doyle M3HIM 05 Sep '06

05 Sep '06

This is really a rhetorical question, as it seems fairly obvious I know, but just to be sure ... What are the correct bandwidths / FM deviations for the ISS Voice, Packet and SSTV VHF and UHF uplinks and downlinks? 73 de Félim M3HIM IO91ot Aylesbury, Buckinghamshire, UK

Norms Rotor Repair
by Emily Clarke 04 Sep '06

04 Sep '06

In the process of getting the U-110 working (which temporarily seems to be the case) Mike KA2AEV sent me a link to a place called "Norms Rotor Repair" which I was previously unaware of. I thought it would be good to post it here for posterity. This isn't a commercial endorse, just pointing out a potential resource for folks. http://www.rotorservice.com/ 73, Emily --------------------------------- N1DID formerly W0EEC - CM87tm Support Project OSCAR - http://www.projectoscar.net

AO-51 back in mode J-FM (and VERY busy)
by John Mock 04 Sep '06

04 Sep '06

AO-51 is in high power mode J-FM this morning. I'm not sure if it's because it's a long weekend, in high power mode, or just off for awhile, but it was VERY crowded this morning. There were several interesting new or uncommon stations on, but they could not be worked at all QRP. I suspect they were having trouble as well. Eventually, folks did figure it out and paused to wait for a new/uncommon station to answer. It might be my own prejudices (as i haven't listened to the recording yet), but earlier in the pass, it seemed like it was mostly the 'regulars' working a few new-ish stations and each other. While 'standing on the soapbox', i'd say that i'd like to encourge folks to use the high power mode to let stations who have trouble hearing SO-50 or AO-51 to work satellites and get started. I would hope that folks who use mode J-FM on a regular basis would use coastal/oceanic passes, or SO-50, to say hello to their friends and/or talk at length about the weather. Alas, it is these conditions that discourage me from making my nantenna design widely available, as things are like this only discourage and frustrate new users, and easier access to mode J-FM might only make this worse. On the other hand, SO-50 has definitely seen more usage and interesting stations do pop up over the 'States, especially on transcontinental passes. So especially this week, give SO-50 a try, and try to show some restraint on AO-51 so new folks can take advantage of high power mode. -- KD6PAG (Networking Old-Timer, Satellite QRPer) P.S. I had mail to AMSAT-BB bounce this weekend, but retrying ten minutes later succeeded. You might try the same thing if your mail gets returned.
