[Today’s run: 7 miles with Boardtown Runners]<\/p>\n
Years ago I ran an APRS digipeater.\u00a0 Now I am trying to resurrect my APRS station,\u00a0 in receive mode only, to use as a propagation indicator for VHF SSB\/CW.<\/p>\n
I’ve made some progress.\u00a0 I have the radio and the computer talking to each other.\u00a0 I’m getting some signals through the radio.\u00a0 Not very many, but a few.<\/p>\n
And I’ve been working on a script (program) in Perl which captures the data coming into the computer and shows the guts of the packet.\u00a0 It will also print the distance and direction from my lat\/long to the lat\/long reported in the radio packet.<\/p>\n
What I want to end up with is something which will send me an alert of some kind (email, text message, ?) when I start to receive packets\u00a0 from stations that are more than XX miles away.\u00a0 I want it to tell me the direction and distance.<\/p>\n
APRS is a radio mode used by Hams for tracking.\u00a0 You build a little box and put it in your car\/bicycle\/etc which has a radio, GPS, and the smarts to connect the two.\u00a0 Depending on how smart your “smarts” box is, it will send out little tracking packets when you turn corners or when you have gone a certain time\/distance since the last time it squealed.\u00a0 Various people around the country run what are called “digipeaters”, digital repeaters.\u00a0 If you are in range of one of those your little squeal will get repeated.\u00a0 And there are gateways into the internet and maps which show where people are, etc. etc.\u00a0 all of the normal internet stuff.<\/p>\n
I’m not doing it for the coolness of tracking someone.\u00a0 Since all of this goes on as people drive around, I’m going to listen for those signals.\u00a0 When we get a propagation anomaly\u00a0 I’ll get some notification and I can run to my radio, point the antenna, and maybe talk to someone who is normally out of my range at those frequencies.<\/p>\n","protected":false},"excerpt":{"rendered":"
