Default Naval Salute was AC power idea for target practice

Other than Airmail which I already have, and using a Pactor II
TNC/ICOM-802, what kind of software do you use for position reporting
on 10.141 ?



APRS is its own software. It converts the data from the APRS packets (it
uses broadcasted standard packet radio, not pactor) to plot the points on
a crude map/chart then trails the target so you can see where he's going
and where he's been over long periods of time. It also charts fixed
station data like the WX stations on a system.

The APRS software's latest version and the latest maps are on Bob's site:

Look near the bottom. This software is only necessary if you are a ham
and going to run APRS on the air. The only thing you need to watch it on
the net is your browser on findu.com.

Hookup is just as simple as your Pactor modem.....You'll need a packet
TNC like a Kam XL:

which does 300 baud, narrow-band audio for a ham SSB transceiver. HF
packet is very narrow banded compared to VHF. It has to fit in a CW
channel to keep the government bureaucrats happy. We use a 170 Hz AFSK.
Kam also does Pactor, WEFAX, and all the other modes. It also is
engineered for APRS HF/VHF crossband repeater and inband repeating.
Other APRS stations on both bands can all be used to repeat your packets
as "digipeaters" to fill in the holes caused by HF propagation.

Oops...looks like the KAM only does Pactor I so you're stuck with the
proprietary modem for II.

Be sure to set the M-802 on LSB for packet....
