Hamvention 2015 report

The trip to Hamvention 2015 in Dayton, OH was a fun time.  So many people and their organizations to get to speak with.  It seemed that many of the satellite-related groups haven't had much contact with each other.  As such, most of my time was spent talking with people from AMSAT, SatNOGS, and others to make acquaintances and find common ground and needs.  Lots of fun, but way more talking than I normally do!

In lieu of a better writeup, here are a bunch of pics from Twitter involving where I was.  If you click through to see the pics, you can find me on the side of a few frames, kind of like "where's Professor White"...

Slow-scan TV from the ISS

Last weekend and into this week the International Space Station was broadcasting SSTV signals on the ham station's 145.800 MHz FM downlink.  On Saturday the pass was high enough for my cheap UV-5R radio to pickup the signal and the timing was right to catch them during the broadcast and not in the 3min silence interval.

The result of an android phone running Robot36 sitting next to the radio:
The green lines were times when the signal went silent for a bit.  First time we've received and decoded space signals!

Single-board computer up and running

Shortly after arriving in the mailbox, we have our pair of ODROID-C1's up and running!  This single-board-computer is similar to the Raspberry Pi 2 but better in most respects, yet still about $35.  The fact that the USB ports and GbE port are not shared on the same processor bus should come in handy for streaming raw I/Q samples from the SDR to somewhere else on the network.

Thanks to +Mike Good for giving both of the boards the shakedown.
