Yes, actually, Scott provided one I uploaded to my MAP60C (suitable
for most any Garmin mapping unit, not just one US$600 model) and my
tracker2 does an admirable job of taking advantage of it.

Garmin, Kenwood.  Kenwood, Garmin. When can I download the firmware to
upgrade my D710?

Eh?  gigaparts lists the radio as $599.  That's not free.  If I hook
it to a weather station, it's not doing other things.  That's not
free, that's retasking.

And if you're using it for something, you can't necessarily use it for
something _else_ at the same time.

Oh, come ON Bob - it's in the spec formally adopted by committee, and
repealed in your "spec" updates on your web page specifically because
the D7/700 couldn't do it!

I'm not asking about the station list, I'm asking about RAM for IO
buffering.  This is something that is important to network devices
(e.g. TCP/IP over packet).  One common complaint about the D7/700 is
the single packet buffer makes it unsuitable for many non-APRS uses.


I don't know why I get myself into these discussions.  To the original
poster, sorry if I hijacked your thread.  The D710 is surely a quality
radio; I would probably buy one myself if I didn't have a 700 already.
 Before you buy, look at the capabilities of a Tracker 2 equipped
Alinco DR-135.
