APRS Paths And Digipeating 101
http://wa8lmf.net/DigiPaths
Main Ham Radio Page. Updated 15 June 2016. APRS Digipeating and Path Selection 101. This discussion starts by describing the traditional APRS path conventions now considered obsolete. This makes the reasons behind the "New Paradigm" shift to exclusively WideN-n type paths (that do away with RELAY and plain WIDE), easier to understand. Jump To Today's Recommended Path Settings. Lower Down On This Page). WHY DIGIPEATING IS REQUIRED * *. The implication of this is profound. Every transmission made on th...

Skip to main content. Ldsped in a soekris. This project is all about a simple, network connectable TNC. After working on a linux packet engine ( ldsped. To be able to run UI-view on my PC's and having the TNC on the linux box, I wanted to go a bit further. While the linux system is far more able to interact with other programs (ie MRTG), the purpose here is just to have a basic system. Then I thought of a baycom device. But then I saw the light! I found the amazing TNC-X. Very little glue is necessary to...

APRS - M0BPQ Amateur radio
http://m0bpq.weebly.com/aprs.html
I have been active on APRS, the Automatic Packet Reporting System since 2008. Rather than bore you with the details, take a look at wikipedia. Which explains all. If you are in the UK, M0CYP. Has a great site with lots of information on settings and how to use UI-VIEW, the most popular APRS software. I have two stations. One at home that runs as a fill indigi and I-gate and another remote tracker in my car. The antenna is only a 1/4 wave, but that seems to do just fine locally. Create a free website.

Se bilder fra aktivitetene som forgår i klubbhuset på torsdager. Hver torsdag blir det bygget, testet, modifisert og reparert utstyr! Det er bare å komme innom og være med. Normalt starter vi kl. 19.00. Uttesting av radio i felt. Hver mann sin radio og antenne (bilder nedenfor). Sjekk/vedlikehold av RPO-mottaker 80m. Bygging av kort antenne for 20m (høy stemning rundt dette under demo førte til spontanbygging). Utprøving/demo av IC-718, IC-7100 og IC-7200. Programmering av Icom ID-80. 13 stk. deltok.

playing with bits: APRS Station On a Boat - Part 1
http://bradthx.blogspot.com/2014/05/aprs-station-on-boat-part-1.html
Thoughts of a computer scientist focused on electronics. VHDL, RF, DSP, PIC, Digital, Analog, plus anything I find interesting at the moment. Wednesday, May 7, 2014. APRS Station On a Boat - Part 1. For the TNC I ultimately decided on the TNC-X. It is available in kit form, is inexpensive, supports the KISS protocol, has a USB interface, and has great reviews. I hadn't built a kit in probably 15 years, but I found this kit to be a simple build taking about an hour. For APRS software I chose Xastir.
