SSB Antennas
"Larry W4CSC" wrote about AIS / APRS:
Every boat should be on APRS on both HF and VHF through assigned VHF and HF channels. Every packet APRS station can be a repeater for ever other APRS station, far extending the range of the individual stations. Some stations are connected through the internet to the national APRS servers hams have setup, including www.findu.com. It's all voluntary, of course, in true ham radio tradition. For the marine application of APRS, visit Bob Bruninga, APRS' inventor, at the Naval Academy website: http://web.usna.navy.mil/~bruninga/aprs.html He tracks the Academy's boat fleet with APRS on them. I fixed one of the APRS stations on an Academy yacht when it was in Charleston a few years ago to put it back online with APRS on VHF and HF. It keeps our Midshipmen from being too lost...(c; Larry, are you aware of any "findu" type charts that are adaptable to APRS? Mapquest "maps" display a poor graphic when plotting a vehicle on long bridges like the type that interlace the Hampton Roads Va area. It's not that the position reported from GPS is inaccurate, but a graphic representation becomes muddled when bodies of water are shown by Mapquest. We're thinking the mapquest maps would accordingly be of little use in this area as a result, but have not actually tried the equipment from a boat yet. Jack Va Beach Va |
