vhf Taits T700s, I have a board that I designed to fit inside of the radio
where the selcal board lives, and correct programming allows you to turn off
and on the APRS using the AUX button, It used the TT4 dip chip only problem I
found is you have to be committed to the project as the chip ‘MUST’
be soldered to the board, but worked very well.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=3 color=black face="Times New Roman"><span
style='font-size:12.0pt'>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.<br>
<br>
You don't have to be real smart to realise that a system that <b><span
style='font-weight:bold'>cannot</span></b> listen doesn't comply with the
Australian LCD.<br>
<br>
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;<br>
1. a tracker and GPS<br>
2. a receiver with the busy line connected to the TT3+ to ensure no tx when the
channel is busy.<br>
<br>
It's small, light, cheap and conforms with the LCD. There are many equally
cheap options available.<br>

Possibly not the absolute best solution, but certainly seems to do the job in
