Another month, another Tech Night! This one was a good opportunity to show off portable APRS gear, GPS receivers etc. Nick VK2FS brought a handheld radio and TinyTrak 3 as an APRS tracker, Phil VK2BDF showed us his custom made GPS satellite plotting software and Geoff VK2AVR was hacking around with some recently acquired GPS receivers and succeeded in getting them to transmit additional NMEA sentences.
Nick’s APRS setup:
Phil BDF’s custom software. Click the darker images – the breadcrumbs show the path of GPS satellites as they fly above your heads – the “hole” is to the south and shows how GPS satellites don’t fly over the poles!
