On a side note, if anyone has old equipment they be willing to part with, I am looking to try for a launch myself at the convention. Or if someone is within...

After reviewing the weather predictions, we are aiming for a more precise launch time (weather permitting) of 0200 UTC (9:00PM Eastern Time) from Island Home...
What date is launch? 73's Kc5wxc _____ From: GPSL@yahoogroups.com [mailto:GPSL@yahoogroups.com] On Behalf Of gregwilliams@... Sent: Sunday, January 13,...
Its still transmitting, but bad GPS checksum. I dont know if thats only on the 2m transmitter or if it will carry over to the 30m if/when it gets out over the...
It is unlikely that the HF transmitter will come on. It won't activate unless the GPS bad data condition is corrected. At this stage, the most probable...
I've never seen one, but the checksum is intended to detect noise on the NMEA serial data link. Could be RF on the line, but also could be a funky GPS or...
Looks like our Mark Caviezel ZP balloon is faring better than our GPS, according to the digipeaters it is coming through, it appears to be nearing the atlantic...
All: I haven't kept up with what the ARHAB state of the art for airborne GPS units is. What units are being used now days? Factors of merit: low power...
Taylor University's High Altitude Research Platform is flying HARP 57 and 58 today; callsigns are kb9znz-11 (currently in the air) and kb9znz-12 (launch in...

Dear friends, BASE 20 has been located on the beach in Port Burwell Provincial Park in Ontario. A Canadian man walking the beach discovered the payloads on...
The GPS 18 LVC (OEM) has worked flawlessly out here in Maryland (we have ~4 of them). I'm sure its obvious, but cut most of the wiring off as it weighs about...
Ralph W0RPK maintains this page of GPS receivers that have passed or failed the 60kft test: http://showcase.netins.net/web/wallio/GPSrcvrsvs60kft.htm One note...
Congratulations! That counts, technically, as a recovery for Ralph's archives. And it sure does highlight the value of including a "return to sender" contact...
I'd think a CR123 LiSO2 cell would keep the GPS CMOS alive nicely even down to -40C, which shouldn't be too challenging an interior temp to stay above. The...
3/4" thick Styrofoam is transparent to GPS signals, so you can keep the GPS inside the capsule but near the top of it to stay warm. Paul ... I'd think a CR123...
... But, this all depends on the payload use. We here at NSS learned this the hard way last fall. This unit does NOT like 439.25 ATV signals. We found this...
Joe -- This would be interesting information but it is anecdotal in nature, very time consuming to collect and very difficult if not impossible to maintain in...
