Recently, I went on a trip to the Black Rock desert in Nevada with a group from the University of Washington to launch some high power amateur rockets. Seeing as though this is a thirteen hour drive from Seattle down to Black Rock, a number of days out on the playa, and another thirteen hours driving back, I though it would be an interesting use of an APRS tracker.<\/p>\n

So, I rigged up a board I had for another project, which already had a microprocessor and a GPS, with a MX614 packet modem IC and a radio interface for my yaesu handheld. Powered the whole lot off a couple of 7AH sealed lead acid batteries, and stuck a mag mount antenna on top of the vehicle.<\/p>\n

The system I mooched for this little project also happened to have several atmospheric sensors on it. Including barometric pressure, humidity and temperature. So, with a bit of modification to my original APRS tracker code, I had it sending position packets as well as weather report packets.<\/p>\n

Coverage out on the playa is excellent thanks to the friendly hams at the Black Rock Amateur Radio Association who maintain several digipeaters as well as a couple of voice repeaters for use in the area on and surrounding the Black Rock desert. You can visit their website at cq-blackrock.org<\/a>.<\/p>\n

Anyway, with the help from the local digipeaters, my packets from out on the playa made it out to aprs.fi<\/a>\u00a0from which I downloaded the data after I got back home. Which you can now get from me here: APRSFI_RAW<\/a>. The all the data is in standard APRS position and weather report formats.<\/p>\n

To bring it all to a close, here’s a picture of the setup I had.<\/p>\n
