Lynn, KJ4ERJ, has just released new versions of his APRS client for Windows PCs and Windows Mobile. Among a whole host of improvements the client can now communicate with RF via TNCs. It also supports read-only use of AGW Packet Engine. Information about the software and downloads can be found at the APRSISCE Yahoo Group. Lynn has also created a Wiki for information about APRSISCE.

I set it up the Windows version APRSIS32 with AGWPE in sound card TNC mode connected to my Elecraft K3 tuned to 30m. The screenshot shows the position reports and beacons received. Actually this does not represent the stations received, as some of the icons are for stations that were digipeated by HF gateways on 30m.

I did this more for curiosity's sake and to help test Lynn's program, as I personally don't have any interest in operating APRS on HF, whilst the lack of VHF APRS coverage in this area makes the cellular data network a more effective means of using it for me.

I am interested in investigating the possibility of using APRS on VHF as a means of detecting Sporadic-E openings on 2m. But for that I will be more interested in the location of the station that transmitted the packet I heard rather than the location of the station that originated it.
