Hello group,

About this time last year I introduced the APO2 to protect vehicle batteries 
from being discharged by radios left on. Today I'm pleased to announce the 
latest-and-greatest, the APO3.

APO3 is a black box designed to prevent a vehicle battery from being 
discharged and damaged by a DC load. Typically it is used to switch a radio 
transceiver off 10 minutes after the vehicle is shut off. 

This is for use with mobile APRS stations. It allows the radio to transmit a 
few position reports after the vehicle is shut off and then it turns off the 
radio and GPS to reduce clutter on the APRS channel and prevent the vehicle 
battery from discharging.

I'm offering assembled and tested APO3's, kits, and all of the technical 
information you need to build your own APO3 and not pay me a dime. :-)

Thanks and 73's,
