FUNcube Datawarehouse Maintenance
by David Johnson 13 Feb '15

13 Feb '15

Hi, I need to make some changes to the services which support the data warehouse and there may be some outages between 10:00 and 20:00 on Sunday 15th Feb. Specifically I am moving from Tomcat to Glassfish as the web application server to enable better long term control of the system and from Java 7 to Java 8. I will try to limit these outages to when the satellite is over the Pacific. 73 Dave, G4DPZ

by Skyler F 13 Feb '15

13 Feb '15

Hello, This is Skyler KDØWHB here, I have ran the Colorado Amsat net for about a year. When connected to the East coast reflector, I get quite a few check-ins, but dont' do anything with them, they just sit there. Last night, I was not connected to the East coast reflector, because its AllStar bridge was down, but here is the list of check-ins for 2/12. kd0mdpJeffColorado SpringsK0jscJeffCanon Cityad0jlRichard Pueblo kb8jnm MichaelEastern Ohiok1ddnAmandaCanon Cityw0dhbDave Longmontkd2hwnJohn Rochester NY If anybody wants to join the net, feel free to, we are on IRLP, AllStar, and EchoLink (not recommended).

K1N on FO-29
by Paul Stoetzer 12 Feb '15

12 Feb '15

Great to hear so many stations working K1N on FO-29. I worked them on the 2008Z pass and listened to the 2151Z pass. Here are my recordings of the passes from my south facing balcony in Washington, DC. https://soundcloud.com/paul-stoetzer/k1n-on-fo-29 https://soundcloud.com/paul-stoetzer/k1n-on-fo-29-2151z-12-feb-2015 I hope everyone who wasn't able to work them today can get them over the next couple of days. 73, Paul Stoetzer, N8HM Washington, DC (FM18lv)

K1N - Worked at 2011 UTC Wed- Check on the next pass
by Grant Zehr 12 Feb '15

12 Feb '15

After my long list of instructions, K1N showed up on the east coast pass of FO-29 this afternoon and was listening almost exactly on his own frequency. I managed a QSO by ignoring all my previous advice (!). Only a few stations were on. I'm guessing that he will be on during the next pass (AOS around 2150 UTC). Good luck and Good DX to all. (If he gets busy, he may go split in which case my previous suggestions apply) 73, Grant AA9LC

Re: [amsat-bb] funcube dongle
by Stephan Greene 12 Feb '15

12 Feb '15

I'm looking into a different approach - USB extenders that use Cat-5 or better cables. For home use, Cat 5 is MUCH cheaper than decent coax, even if I have to replace it periodically from exposure or errant lawn mowers. And ZERO possibility of transmitting directly into it (probably still have to protect against 3rd harmonics when operating mode VU). As an interim test, I used my usual LMR400 into the shack, then the dongle and a coil of about 50ft of cat 5 and the USB extenders. Seemed to work well receiving AO73 telem - no worse than dongle straight into the PC. Need to try it again with the dongle at the antenna. Goal would be a weather proof enclosure and as close as I can get the dongle to the antenna. Bought the cable and extenders from Monoprice; don't recall the model. This approach would work well, I think for portable ops, too. Maybe without extenders, just a long USB cable. I think USB 2.0 is rated to 10-15 ft without boosting the signal. 73 Steve KS1G > -----Original Message----- > From: "Clayton Coleman" <kayakfishtx(a)gmail.com> > Sent: Wednesday, February 11, 2015 10:37 > To: kb2m(a)arrl.net > Cc: "AMSAT-BB" <amsat-bb(a)amsat.org> > Subject: Re: [amsat-bb] funcube dongle > > > > Jeff, > > Like Alan, I use a manual system to switch between the transceiver and > the FCD.
