AO-10, AO-13 890 GROUP
by books47925＠mypacks.net 02 Oct '08

Hello Satellite Ops, While reading KD1K's posting, I was thinking about the old 890 group on AO-10 and AO-13. I would like to hear from any of the guys, that might read the bulletin board. Please send a direct e-mail. I sure do miss those round table discussions, and all the interesting comments about numerous topics. Although I was mostly interested in working DX, it was always nice to hear voices from around the World. Best Wishes & 73, Steve KB8VAO

How about the AGC is being supressed by Pave Paws radar when it's within range of the miltary stations?? -45dBm at the antenna would put amateur signals down by 40dB David

Go figure. I could hear my down link pretty good on the 13 degree pass but nothing on the 50+ degree pass that followed. Still trying to figure DO-64 out. Mike (K9QHO)

Re: [fieldops] What do you do with satellites?
by Eric H Christensen 02 Oct '08

Dick, I'm looking for something a little more than just HEO v. LEO. I'm looking for modes of operation. While I'm excited about our next HEO opportunities I'm not going to write a story discussing the benefits of either type of orbit as this means little to a new operator (the target of my story) and does nothing but stir up flame wars within the community (which doesn't do anyone any good). So far, people have discussed the telemetry and the physics of satellite theory, the educational aspects, and portable operations. I'd love to hear from someone on the use of PACSAT birds, APRS, and maybe some keyboard-to-keyboard digital modes (PSK31 anyone?). 73, Eric W4OTN >Eric: > >This is where the "beauty" of HEO satellites are seriously missed.

DO-64
by WILLIAMS MICHAEL 02 Oct '08

02 Oct '08

I got a decent down link signal return from DO-64 on the first morning pass at 13 degrees elevation. Considering my antennas are at only eight feet with ground clutter (trees and buildings), the signal seemed about the same strength just after launch. As usual, the first half of the pass was the best signal strength wise. Waiting on the next pass at 52 degrees. Mike (K9QHO) AMSAT 33589

Advertising Shuttle Retransmission Faclities on APRS
by Robert Bruninga 02 Oct '08

02 Oct '08

To Shuttle rebroadcasters: Many people do not monitor your Shuttle Retransmission frequencey all the time, and so, may not remember that the Shuttle is in orbit. Therefore, a TNC should be connected to the Retransmitter that activates an APRS beacon on the local APRS channel whenever it is keyed. This APRS beacon will alert all mobiles on the front panel of their APRS radios in range that the retransmission is in progress. We need to get this info out to all volunteer rebroadcasters... This web page shows how to use just an old TNC and no special software to format the beacon so that it shows all the relevant information right there on the front panel of the mobile APRS radios: http://www.aprs.org/On-Air-beacons.html This technique also applies to all re-broadcasters of the Newsline, RAIN report, ARRL Audio file, and any other general info nets that need to be heard by all radio amateurs. APRS is your universal real-time ham radio information channel. If you have info to share, beacon it on APRS live. Monitor APRS and see what is happening in your area. Bob, WB4APR
