Oops. That would be me. Jim I have a replacement radio ready for you.
Are you going to be in KC anytime soon?

Kevin,
Thank you for considering HamHUD V; the HamHUD team is really excited about
it, too. But if you're looking to get an APRS rig right now, and you're
not willing to wait a few more months, then you might better go ahead and
get the Kenwood D700a at Dayton.
HamHUD V kits will NOT, repeat WILL NOT be sold at Dayton this year. There
is a rumor going around to the contrary. Close, but not quite. We will
only be showing the "demo board", with "demo" firmware, in order to get
valuable feedback from our propective customers. We WILL be taking orders
for _HamHUD II_ kits, for people who already have a D700a/DR135t/TNC, and
don't want or need the fantastic capabilities that HamHUD V promises.
Anyway, the plan is for HamHUD V kits (as well as fully-assembled units) to
be available in the fall. And don't forget, you *still* could connect the
HamHUD V to your D700a.

I keep hearing this from hams I meet everywhere, and that's a good thing.
There's a revolution brewing that the major ham radio manufacturers are
doing nothing about. A new generation of hams has arrived to LIKE to
"tinker": they want to modify their radios, adjust things, try new
modulation types, etc. It's that whole "advancing the state of the art"
thing. Often, that means they need to change the radio's firmware to
accomplish their goals. I don't truly understand Kenwood's reasoning on
locking down their firmware, but HamHUDs have been and always will be open
source.
And Kenwood's reasons can't be of a regulatory nature. The FCC recently
clarified its position on open-source and software radio in the amateur
bands. They want to encourage them as much as possible, and put as few
restrictions on firmware as possible. It's sad that radio manufacturers
can't see as clearly as a government bureaucracy!
>So what cool features of APRS will I miss if I go with the d700a?
Strictly speaking, none, because SmartBeaconing is not part of the APRS
specification. But SmartBeaconing produces tracking data far superior to
fixed beacon rates, with lower QRM. This is true even if the fixed-rate
tracker uses PROPORTIONAL-PATHING (which HamHUD V will support). But you
can get SmartBeaconing by combining a HamHUD II (or V) with your Kenwood
D700a. You may want to buy both ;-)

The HamHUD team hopes to change that ratio ;-)
And note, the trademark (registered pending) is HamHUD, "H" (uppercase)
"am" (lowercase) "HUD" (uppercase).

I could not agree more; desiring this awareness in my mobile station led me
to develop the HamHUDs.

It will be interesting to see what Kenwood will show at Dayton. But unless
they seriously reverse course in corporate policy, three things will remain
the same:
1. The firmware will be closed-source.
2. The flash memory will NOT be user-modifiable (precluding open-source
alternate firmware).
3. They will not incorporate SmartBeaconing.

OK -- after seeing the two messages above, I'm confused. I haven't seen
anything from Jim in quite a while -- did I miss some emails to the
APRSSIG? Or were these posted to a different list or something?
