Rob,
If all you plan to do is run packet/APRS on 2 meters, I would
suggest that the KX3 is a waste of a good radio. You'd be better served
by buying an inexpensive 2 meter FM rig. It has everything you should
need, and I'm unaware of any APRS activity on 70 cm.
There are two meter rigs that already have TNCs built in like the
ones that Kenwood sells. Or you can use software TNCs by just using the
audio in and out of a sound card. When you think about it, there are
good reasons to have separate VHF and HF gear.
73,

Howdy!
I'm quite intrigued by what the KX3 can potentially do as an SDR, and
am
considering trying to get one. There are some downsides to the KX3
I've
noted (price and lack of 70cm being two big ones), but the
possibilities it
opens up are pretty awesome to imagine.
I've been playing around quite a bit with packet (AX.25 and APRS over
2m
thus far) and am having a hard time figuring out if the KX3 offers
advantages over a traditional transceiver's data port. They both
/appear/
to require a TNC, although I'm not entirely sure if that's actually the
case with the KX3.
Is anybody doing 2m AX.25/APRS over their KX3 who could share some
details
about their setup? I'm really close to sticking with a simple VHF/UHF
mobile instead of the KX3 as packet is a majority of what I'm
interested in
right now; then upgrade to a KX3 when I have the time to get into HF -
but
if the KX3 offers true advantages in this space, I may get my forever
radio
in a KX3 now...
Thoughts?
