AMSAT @ Arizona ARC "DeVry" hamfest in Phoenix AZ (20 April 2019)
by Patrick STODDARD (WD9EWK/VA7EWK) 10 Apr '19

10 Apr '19

Hi! I will have an AMSAT booth at the Arizona Amateur Radio Club's annual hamfest on Saturday, 20 April 2019, in the morning. The hamfest is held at the DeVry University, along Dunlap Avenue east of I-17 exit 207 in Phoenix. The hamfest is a morning event, scheduled to run from 6am to 11am (1300-1800 UTC). During the morning, WD9EWK will be on the air for demonstrations of satellite operating. The hamfest site is in grid DM33, in Arizona's Maricopa County. If you hear WD9EWK on the air that morning, please call and be a part of the demonstration. All QSOs will be uploaded to Logbook of the World after the hamfest. QSL cards are available on request - no need to first send me your card or SASE; just e-mail me directly with the QSO details for verification against my log. I will use my @WD9EWK Twitter feed to post updates from the hamfest. For those who don't use Twitter, these updates are available in a web browser at: http://twitter.com/WD9EWK Thanks, and 73!

Event Horizon Telescope
by Robert McGwier 10 Apr '19

10 Apr '19

During his career developing techniques with his team to do Very Long Baseline Interferometry using widely separated but not connected radio telescopes, Tom Clark, K3IO made major contributions to Radio Astronomy Science and Engineering. Today, we saw another outcome. NSF, EU, and many others announced the VLBI generated image of the 4 billion solar mass Black Hole at the center of the Galaxy Messier object 87 (M87 for shorthand). You could literally see all the way down to the event horizon. The used telescopes all over the world and made the signals coherent even though they were recorded using a record and timing process developed by Tom and his team at NASA Goddard and extended into the modern era with better toys than Tom had when he was the world's most accurate geodicist. And once again, Einstein's theory of relativity was proven right in the most violent laboratory ever "seen". 73s N4HY

KE6QMD Satellite Digipeater?)
by Robert Bruninga 09 Apr '19

09 Apr '19

Is there a satellite that is digipeating APRS packets with the callsign KE6QMD? It is in our list of digipeating APRS satelilites and I'm having a senior moment and not remembering it. Steve Dimse K4HG is in the process of cleaning up the parsing stack at FINDU.COM and I am helping to eliminate all the no-longer used aliases and calls. Bob

HRD Sat Track Rotator Help
by Frank Karnauskas 09 Apr '19

09 Apr '19

I got SatPC32 running my G-5500 via an ERC-M interface on the very first try. (Thanks, Rafael, NN3RP for the great documentation.) Not so lucky with HRD Satellite Tracking and Rotator Control. The Satellite Tracking screen show the correct az/el positions for the rotator. I can steer the rotator with the Rotator app. But, I cannot get it to track an active satellite. I have some screen grabs to share and can provide a succinct statement of what is happening/not happening when I try to track a bird. I am hoping it is something as simple as a bogus DDE button setting. If anyone is not watching the basketball game tonight and is willing to take a look, I would appreciate your kind help. Please contact me offline. 73, Frank FRANK KARNAUSKAS, N1UW AMSAT NEWS SERVICE ROTATING EDITOR 1402 SUMMIT SHORES DR. BURNSVILLE, MN 55306 N1UW(a)GOKARNS.com 612-644-9174

AISAT-1 WORKING OVER NA
by cchunter3＠mindspring.com 09 Apr '19

Umesh, you can also include in the amsatnames.txt file in SatPC32 aux files.. 44104U 19018AC AISAT-1 or what ever name you want so that using different TLE files the Sat name used will be consistent..just make sure the amsatname files match the doppler file names for each Satellite. also I heard you the other day digi thru AISAT! 73 Christy KB6LTY Thanks, I see that it is now included in "nasa.all", and is picked up by SatPC32. However, when I add an entry for "AISAT 1" in Doppler.sqf, the frequency pair does'nt show up. So I ended up working at a fixed frequency without doppler. AISAT 1,145825,145825,FM,FM,NOR,0,0,Pkt Digi ISS,145825,145825,FM,FM,NOR,0,0,Pkt Digi etc... Later, on a hunch I tried other birds with a SPACE in their name and they seem to have the same issue. the frequency pair does not get picked up from Doppler.sqf How do I get around it, any help is most appreciated. 73!Umesh
