Re: [amsat-bb] DopplerPSK and linux

Are you trying to run that from the command line, or by clicking on it in > the GUI? Tried both. Double clicking results in about 2 seconds of the mouse pointer turning into the ubuntu "busy" pointer, then nothing. Running from command line "java DopplerPSK.jar" results in the one line error. > Have you marked the .jar file as executable? looks ok: -rwxrwxr-x 1 dean dean 120002 Sep 19 2015 DopplerPSK.jar > Is the JAVA runtime installed on that PC? ( javac -version ) java version "1.8.0_201" Ok, having written all that, it dawned upon me that AC2CZ's FoxTelem runs perfectly and is also a .jar, so I inspected his "foxtelem" start script to see how he starts FoxTelem. His command line is "java -jar FoxTelem.jar" - I wasn't using the "-jar" part. DUH. Just tried it with the following terminal command and it started!! "java -jar DopplerPSK.jar" Just another case of "OE" -> operator error. --Roy K3RLD

Need two Virginia APRS rovers next Saturday!
by Robert Bruninga 12 Jul '19

12 Jul '19

AMSAT Rovers: We desperately need 2 APRS Mountaintop weekenders for 4 hours on Saturday 20 July for the Annual APRS Golden Packet event from Maine to Georgia along the Appalachians. Goal is APRS messages the full length and into Canada. One needed station is in SW Virginia on top of Comers Rock near Wythville, VA and one in Northern Va on Hawksbill Mountain east of Harrisonville, VA. All of the other 15 mountains are signed up. It is a 4 hour event 11 AM to 3 PM. Both of these sites are drive-up except for the last hundred yards or so to the best operating position. http://aprs.org/hamtrails/comers-rock.html http://aprs.org/hamtrails/hawksbill.html Prove your APRS stuff! And enjoy the view and drive! Full event details: http://aprs.org/at-golden-packet.html PLUS, we will attempt PSAT2 relay on 3 passes during the event. All others hold off please. Contact me.

PSAT2 auto-reset
by Robert Bruninga 12 Jul '19

12 Jul '19

Sorry, PSAT2 auto-reset back to safe mode because we did not get the "we're still here" command uplinked in time. Only modes available are PSK31 and SSTV. We will try to restore normal operation on the next several orbits. Normal mode should show status bits of 01000111. Which has PSK31, SSTV, plus Digipeating plus APRS-to-Voice http://aprs.org/psat2.html Bob, Wb4aPR

There’s a lot to see, so passes will be best effort holiday-style & I’ll attempt to announce on Twitter shortly prior. https://twitter.com/K0FFY_Radio

RF noise from a passing-by BMW i3
by Zach Metzinger 12 Jul '19

12 Jul '19

For those of you considering operating around electric vehicles, beware of the copious noise emitted by the BMW i3. I was sitting in a parking lot, engine off, operating mobile on 10m during the recent band openings. Rather abruptly, the band's noise floor increased to mid-scale on the S-meter. I briefly wondered if propagation had suddenly changed, and then I noticed a BMW i3 pass behind me and leave the lot. The noise left as well... I was back to a nice quiet band floor. I didn't have time to switch over to 2m/70cm SSB and see how far up the racket extended. I stumbled across an article relating much of the same, today. https://www.greencarreports.com/news/1098893_bmw-i3-electric-car-quirk-no-a… So, save the planet or save the spectrum. Perhaps not both at the same time? :-) --- Zach N0ZGO
