[OZAPRS] APRS Tracker

[Ray Wells]

We appear to be comparing apples with oranges when we compare 2m tx ONLY 
trackers with other styles of equipment, for any band, that at least has 
a receiver and at least makes some attempt to prevent transmission at 
inappropriate times.

You don't have to be real smart to realise that a system that *cannot* 
listen doesn't comply with the Australian LCD.

I have a TT3+ and a GPS from the same supplier - about $100 Australian. 
They are married to a Tait T500 that cost nothing because it has zero 
commercial value. The aprs mobile has;
1. a tracker and GPS
2. a receiver with the busy line connected to the TT3+ to ensure no tx 
when the channel is busy.

It's small, light, cheap and conforms with the LCD. There are many 
equally cheap options available.
