APRS world map

APRS is now in its 21st year! APRS is digital communications information channel for Ham radio. As a single national channel (see map at right), it gives the mobile ham a place to monitor for 10 to 30 minutes in any area, at any time to capture what is happening in ham radio in the surrounding area. Announcements, Bulletins, Messages, Alerts, Weather, and of course a map of all this activity including objects, frequencies, satellites, nets, meetings, Hamfests, etc. The APRS network has grown to most countries with strong Amateur Radio populations.

    My project has started. Today I’ve ordered the WX3in1 Plus 2.0 at Microsat. The cable is a CAB20 used for Motorola radios (in the mic port). Hope it will arrive quickly  😀

    The WX3in1 arrived in the mail. Unboxing is usually not very interresting so I’ll leave that out. But quite quick I got it fired up and hooked an old GM340 to the device.

    To gain more out of my APRS digi/iGate, I moved it out in the garage. Here I have connected my Comet GP-1 antenna so the range can be expanded greatly. Sitting around 6 meters up it can reach a bit further that from my window shelf antenna. Take a look at this page to see operational status.

    After the move and getting a better antenna connected, this is how it performs.
