Yes, I understand that, and I'm not specifying a USB-only device. However,
it WILL have USB support, and there are other USB-only TNCs out there now.
USB devices can support multiple configuration modes... why not allow for a
plain COM port emulation and also provide a native TNC interface? At the
very least you'd gain plug-and-play capability so you don't have to tell
your host programs anything about the TNC.

I just picked up a D7A at Dayton for APRS. I was wondering if anyone has
come up with a way to convert data from the ARRL's TravelPlus program to
the Kenwood memory program.
Thanks,

But there are lots of serial TNC's on the market. Again, from a business
perspective, should I enter a saturated market, with both new and used
equipment begging to be bought, or a market that is just emerging?
And while some hams are cheap, sales seem brisk for $2000+ HF rigs and $400+
APRS HT's

I don't disagree with that.

First of all, I'm not currently marketing anything. Even so, I recognize a
business, to succeed, eventually has to make money. That was the perspective
I was trying to bring here.

Being you would need a USB host interface on the embedded processor, I can't
disagree with that. What we have been talking about is USB client, with the
Windows/Linux/MAC box providing the host interface. AKA stuff like KISS
TNC's. It is going to be a long time before you'll be able to plug a USB GPS
into a standalone embedded tracker. But then, there is no shortage of serial
based GPS units.
Again, from a ham hacker perspective, I couldn't agree more with you. But
making 4 layer boards, designing FPGA's and building and stocking inventory
is not free. Hence, if one wants to stay in business, they have to go where
the money is and/or find a unique niche. So far, USB TNC is that niche.

Subject: WinAPRS 2.7.5 released
From: Mark Sproul <msproul@jove.rutgers.edu>

A new version of WinAPRS has been released, the most important improvement
is DRAMATIC increase in speed of drawing TIGER maps.
ALSO heading up is now an option, please see full list below.
Details can be found at http://www.winaprs.org
The new version can be downloaded at http://winaprs.org/downloads/
WinAPRS Version 2.7.5 - May 15, 2004
MacAPRS Version 3.7.5
* WinAPRS now uses off screen bitmaps for drawing map images instead of
drawing directly to the screen
This dramatically speeds up the overal drawing of maps
* Much faster loading of TIGER maps. IMPORTANT NOTE: The first time
it sees new counties, it takes time to convert to binary.
* Heading up option for maps. This allows the direction you are going to
be "UP" on the map
* Rotated labels option
* Varied color states/counties option
* When moving the cursor around, now displays closest polygon
(water body, park etc) landmark and street
* Use CONTROL KEY to hilight road near cursor when moving cursor around.
* Support of compressed NWS weather warnings data
* Bug fix in compressed position parsing to fix ICON.

Yes. Link700 is the way and the means.

Oh, you mean free, sorry I can't help you there. 8^)

I went fthrought the TT stage, then progressed to D-700

The TT3 would be a good choice. So would a KPC-3+ or a TigerTrak
unit. Some people are using the Oncore's. I've used Trimble SV6
boards which can be acquired cheaply. There are also Rand McNally
GPS'es that were intended for Palm PDA's which people have hacked,
people have hacked into their OnStar systems, there were RS GPS'es
on closeout some months back, lots of options.
Nice thing about the TT3 is that you can feed it inverted TTL levels
and just check the box to invert the data in the config program.
Works well for the Trimbles, so you don't have to add hardware to do
it.

You can also use some of the APRS programs to manually plot
bearings, yet not transmit that info to the other hunters. Xastir
can do that.

That's the flame-bait part... Opinions vary. It's been discussed
lately on the SIG, in detail.

Most old TNC's will support APRS just fine, assuming you want to put
up a RELAY-only digi, or an APRS station that is connected to a
computer. You can also hook up an old DOS laptop and run Digi-Ned
to turn it into a WIDEn-N digi. There's a linux version of Digi-Ned
as well.
