04 Mar '09

Hi All, I have the pleasure of talking about Satellite operations to one of the local Memphis clubs tomorrow, March 5. The Mid-South Amateur Radio Asso. meeting starts at 7 P.M., so I will try to make a few contacts on the A0-51 pass at 0050 utc (6:50 pm local time) right before the meeting. I only get 23 degrees max. to the west and will be using an Arrow and 2W HT. I would appreciate any contacts on the upper pair. (145.92/435.300) Thanks and 73, Rick - WA4NVM LM1339 P.S. Just had a nice contact with VE3NPC on the "bent pipe" pair of A0-51 (2220 utc)

Re: AO-7 RTTY telemetry equations?
by Tom Clark, K3IO 04 Mar '09

04 Mar '09

The telemetry equations are in the December, 1974 issue of the AMSAT newsletter available at http://www.ka9q.net/AMSAT-Newsletter-1974.pdf. I don't know of anyone who has made an Excel spreadsheet, and it would be nice for some one to make one available. Phil Karn has scanned most of the archive of AMSAT publications and they can be found at http://www.ka9q.net/newsletters.html. As noted in yesterday's special AMSAT bulletin, W3PK and W4PUJ are currently working to get the first 5 years in PDF format. 73 de Tom, K3IO

AO-51 V/u
by KC2PCR 04 Mar '09

04 Mar '09

Sounds like you may have heard me on AO-51 yesterday- kc2pcr " Strong unintelligible signals for the most part" could have been me tx in USB because that's what it sounded like coming back to me too, then I switched to try LSB and BAMM! I was in there pretty solid & fairly clear, but it was late in the pass so I couldn't hold it for only a moment or two. I didn't hear anyone else in there however Dave KB2MPU helped me get my TS-520 with 2m tv-502 transverter dialed in prior to the pass was also on freq listening and he told me afterwards he copied a few stations calling. LSB seemed to repeat clear verses USB which came back to me garbled. Take care & 73 doug kc2pcr Message: 5 Date: Tue, 3 Mar 2009 15:33:39 -0800 (PST) From: Gary Lockhart <gary_lockhart33(a)yahoo.com> Subject: [amsat-bb] AO-51 V/u usb To: amsat-bb(a)amsat.org Message-ID: <779929.12530.qm(a)web65614.mail.ac4.yahoo.com> Content-Type: text/plain; charset=us-ascii 435.150 FM 145.880 USB What did I get wrong?
