I’ve been trying to connect my Palm IIIxe with the D7A and was partially successful.
PocketAPRS is a software application for Palm PDAs – it allows you to interface between a transceiver and a TNC.
The author of the software, Mike (N0QBF), no longer supports the software. I was able to get a copy of the software, but I’m not sure I’m going to be able to register it – which leads me to believe it won’t work properly. We’ll see.
I did get the software loaded onto the Palm IIIxe and was able to get the Palm to talk to the D7A. But as of tonight, I wasn’t able to receive an APRS packet through the D7A and plot to a Norfolk map on the Palm. Maybe tomorrow.
I’m also thinking of getting a fabricated cable to connect the Palm to the D7A:

Or if I find some software for my Palm T3:
