Craig KL4E e-mailed me (and a few others), mentioning that he
will give an AMSAT presentation to the Chehalis Valley Amateur
Radio Society in Chehalis, Washington, this evening. Chehalis
is between Seattle and Portland. More information about the
club, and tonight's meeting, is available at:
Along with the presentation, Craig plans to give a demonstration
on SO-50 during the 0424 UTC (9.24pm PDT) pass. Craig mentioned
he may be able to work the passes before and after this particular
pass, depending on if people show up early or stay late after the
meeting. If you hear KL4E on, please give Craig a call and be a
part of his demonstration(s).
Good luck, and 73!
(You may resume the discussion about band designators and modes,
already in progress...)
Will activate IN72 Grid next friday, July 8th. Will try to be present at most satellite passes between 0900-100UTC until 18-1900 UTC. Will be present in FO-29, XW series, and SO-50 & AO-85
Even will try AO7 pass for USA stations (just cross fingers for AO7 be active in “B” mode that day )..
For those interested ..: Will activate IN72 grid on next friday, July 8th. Will try to be active at most satellite passes as possible. FM&linear sats. Even I will try AO7 (if we are lucky enough it be in “B” mode active that pass) looking only for USA stations. Cross fingers.
Will be present in FO-29, XW sats, SO-50,AO-85...Opertaion will begin at 0900-1000 UTC until 1900 UTC
Thanks for N8HM for posting my DM77 operation announcement yesterday.
It was a very last-minute trip but went over very well. I made 25
contacts on FO-29 and 14 on SO-50. I attribute that number of
contacts to it being a U.S. Holiday (Independence Day.) Both
satellite passes were very orderly and it was nice to get a few new
stations in my log.
We had been in very mountainous terrain during the trip to the
destination grid. Fortunately DM77ab was just east of Antonito,
Colorado in a high valley. My GPS was reading an elevation of 7,864'
at my operating location. Using 4 elements on 70cm and 2 elements on
2m, I was able to work both satellites down to the horizon.
All of the contacts have been uploaded to Logbook of the World.
We have been using the term "Mode K" to describe 21 MHz uplink/29 MHz
downlink because that is what AMSAT called it when it first came into use in
1987. Similarly, the terms "Mode A" and "Mode B" came into use in 1974
because that is what the engineers who designed AMSAT-OSCAR 7 called them. AO-7
actually has four modes: Mode C is a low-power version of Mode B, and Mode
D is "transponder off." Then came Fuji-OSCAR 12 with Modes JA (analogue)
and JD (digital), where "J" stood for "Japan." FCC even included the
definitions of Modes A and B in the written tests of that era.
This "ancient history" has probably served its purpose. Art is right:
we'd do better to stick with the numbers.
