Alfa Spid Rotor Question
by Bob Leavitt 27 Jul '20

27 Jul '20

Our Grade School has been selected to participate in the NASA ARISS program. We are working to have our station setup for the scheduled October ISS contact. We are having a problem with the Alfa Spid rotor controller, in that it can see the port but cannot talk to it. This problem was duplicated by the technician at Hy-Gain (US Distributor). Has anyone else had a similar problem? If so, is there a solution? TNX 73, Bob KEØSDV

Historical Data download for FOX-1A?
by Bill Gaylord 27 Jul '20

Is it possible to get some sort of download for the Historical Telemetry downlinked by Fox-1A? It would be interesting to study its life in space. 73 KD9KCK

Coax failure
by Russ Kinner 27 Jul '20

27 Jul '20

Well, my shortcuts in installing my VHF/UHF antennas finally caught me. I took the antenna down and it got away from me so the coax was kinked where it exited the house and the shield and center conductor opened. Very nice peak in the TDR function in my Nano-VNA where the open happened. New coax connectors on the way with the proper lightening connector so I can better protect the installation. You take short cuts, you eventually pay. So I'm stuck at 98 confirmed LotW for a few more days. Even with 50 years licensed, sometimes you get a lesson dropping you down a notch or two. Rusty.

Roy Dean: You need a little education. “Spam” is irrelevant or inappropriate messages sent indiscriminately to all audiences. “Advertising” is the activity or profession of producing ads for commercial products or services. What do I offer on my Web site? Information. Free-of-charge. No product nor service that benefits me personally. SO … What I did - post ANTENNA PROJECTS to groups entitled “antennas,” “satellites,” and “DIY Projects” is really quite an appropriate use of the ‘Net. No spam. Target audiences.

It seems that we're relying more and more on Internet-driven communications to schedule our satellite operations, rather than using our amateur radio resources. Shouldn't we be getting bulletins through the satellite itself, perhaps on the telemetry channel? I recall this being done on a previous satellite. Perhaps this is why we're losing spectrum allocations? Food for thought. --- Zach N0ZGO
