2015-08-27 A lot more APRS with a mobilinkd
I tried APRS (automated packet reporting service) before and wasn't convinced I was going to use it much. A later attempt in tracking my location on an amateur-related trip from Apeldoorn was also not much of a success.

But, on our recent holiday in the southern part of England I also tried recieving what was available on the 2 meter and 70 centimeter amateur bands and I noticed at a campsite in the New Forest that there was a lot of traffic. I decoded this by putting the android tablet with APRSdroid close to the radio. Part of the traffic was decoded and this gave interesting things such as announcements of local repeaters. I also heard a lot of packets that weren't decoded by the setup with the microphone of the tablet.

So my interest in APRS was revived. And I knew of a much nicer solution for APRS with Android devices: the Mobilinkd bluetooth APRS interface. So I bought one and 'connected' it to my Android tablet. It recieves a lot more local packet activity than my first attempts, I see digipeated packets from as far as northern France. And today I tried transmitting my location on a short trip. The results weren't ideal since the trip was a lot further than the logged points, time to look at the audio settings for transmit.

The Mobilinkd is quite small, it can hide behind my Wouxun KG-UVD1P radio.
