Land Ops - The Off Road, Navigation and Amateur Radio Search Club
Ric, We'll get more members migrating to the forum and more answers. The one to respond is John Emig W6CYS. He told me what he was using, but it slipped my mind. I use UIview on my laptop.
It's a wide variety of devices and software. Today I have to return a tracker to Ed Gonzales which is a misc package of connections, GPS and TNC. Others have beacons in radios. The readers vary as well. We'll get this discussion cooking as more members slowly come over.
Wasn't at that OP, but... I use USAPhotomaps by JDMCOX software (freeware)
You can download maps/b&w aerials to your laptop. I ran it with a Kenwood TM D700 acting as the TNC. Haven't used it in a while though.
Doing that doesn't allow you to use the TMD700 in APRS mode. The software running on the computer becomes the APRS unit, not the control head. I used a PMCIA gps card as the GPS.
During the BB Night Op we used APRSIS/32 running on an HP laptop. Rather than a physical TNC we use a virtual TNC, DIRE WOLF, which uses the computer's sound card to decode the packets and send them to APRSIS/32 for display. All the software is available for free in the internet.
What you were seeing in the video is a 21-inch display driven by my laptop. Makes it much easier to see the icons on the map.
Hope that helps. Any questions, please ask. The personal e-mail is email@example.com.
Thanks John for the info.
