Just my opinion here... Not of anyone else - certainly not of TAPR.
I have my fingers in all sides of this issue. I use APRS in both HAM and
COMMERCIAL applications. I do not operate APRS on HAM BANDS where I am being
paid to operate, but I do operate APRS on Commercial Bands on Commercial
Frequencies. I write software that I provide for free and commercially for
Ham and Non-Ham users (OziAPRS). I do the same with hardware (AntiTracker).
My belief is that it is up to the author to add their own restrictions on
the license. I cannot speak for other authors, but all I want is some return
for the work that I have put in.
And when I do commercial work, I attempt to ensure that those people who
have invested in the technologies I am using are rewarded for this. That
means that I buy TinyTrak III's from Byon. I register extra copies of
UI-View that I don't need as requested by Roger Barker.
How much I charge for my software depends on the ability of the client to
pay. Right now there are people using my OziAPRS software all over the world
- on commercial and free terms. I people want to use the software
commercially they can.
With my AntiTracker, I do place a restriction on the use of this
commercially, since it was developed for my consulting work, as a way to get
work for me. And by allowing it's use by the Ham community I am not
affecting that work.
Unfortunately in the tracking field there are many people operating
unethically. There is a company here in Sydney that will lease a radio like
a D-700 for US$2000/year (three year term), and sell software very similar
to UI-View for US$25K.
In another example, one client just advised that they were given a quote of
US$150,000 for a tracking system for 5 vehicles with computer display over a
flat ground, along a 5 mile track.

The GNU GPL is a very complex license that tries to do a very simple
thing; put everyone on exactly the same footing. But as you've pointed out
there is always someone who has more rights over the code, and that is the
copyright owner. As owner of the code, you have the right to license it
multiple ways, including providing non-GPL licenses for certain uses. You
might choose to do that if you think that the GPL is good for some
things but not for others (as Larry Wall did with Perl). Or you might
offer non-GPL licenses to companies that want to develop products with
your code, but whose own licensing policies are incompatible with the GPL.
That relicensing is not very common from what I've seen, but it certainly is
done. Obviously it only works in the case where one entity controls all
the copyrights for the code in a package or system and therefore would
not be applicable to the Linux kernel, for example, but it would seem
to apply in the examples being discussed here.

Thanks all who replied to my question how to get a TNC out of kiss mode
into host mode. The suggestion from John W2FS works fine, I just cat the
kissoff.dat file to the serial port and the TNC gets back into host mode.
Now to create a small program that takes these commands as normal text and
sends them in binary to the TNC. This way I can also pretty easily
reconfigure the TNC with other parameters as needed.
Thanks for all your replies,

OK, for the sake of arguement... (And not to start one!)
Let's say someone makes a weather station.
And it's not APRS compatible at all.
But they want to add an APRS hook.
Should they go with one of the existing standards? Which one?
And are they anthing in the way of gotchas that could be fixed?

Hi All-
At the APRS Forum at the Tampa Hamfest ( attended by none other than Bob
B.) there was some discussion of the inability of the Kenwood radios to
filter weather messages no matter what the settings. There were some
there who did not want any wx period. It was decided to change the
rest of the clients by June of 2004 to allow filtering on the
server side. I had started doing this last spring by sending
messages to "NWS_" rather than "NWS-" mainly to implement a
compressed format and not crash the present software. Turns out
the Kenwoods ignore these packets. I tested Ui-view and xastir and
found they already dealt with the server side filters completely, and
since now is sooner than June, the change has already been made.
Yesterday there would have been only one forced "NWS-" packet seen on a
Kenwood. That would have been only in part of North Carolina. If for
some reason you want to see these compressed packets on a Kenwood, set
up a message group of "NWS*".
This doesn't change the severe wx packets- tornado,severe
thunderstorm, marine warnings etc. just the things like winter weather
which can swamp the message buffer of the D700 & D7. (I live in
Southwest Florida and consider a snowflake life-threatening, but most of
the US doesn't think like that.) Remember there is a position packet
sent for every weather advisory area to allow a mapless mobile such as
a Kenwood to have some idea where and what the situation might be.
Position Packets cause no harm- they are not "sticky".
I also changed the icons to better match what was going on- "Snow "
for winter wx , "Gale" for High wind, "Fog" for fog. And while I was
changing things- I have made the comment area on the Kenwoods a little
easier to see what the alert is about- "FlashFlood Statement" rather
than "Center of FFS Area" for example.

Richard, N4GPS, is correct the band was really open between 1800 and 2100
last night. I made a connect with G1YFF and F1CHJ I also copied G7SUH,
M0NAS, and Weather stations, F1DPI-5 and F4BNZ all on 30 meters.
Interesting to see the 47F temp in France.

It can be done!
I was able to take apart a moulded Garmin GPS connector and fix a broken
wire at the pin. It was distructive to the existing (remiaing
wire), but once apart, I could re-wire all 4 pins as needed.
Its not easy and take a lot of fuss, but using two jewelers scredrivers to
just scrape away the glue, eventually the back could be pried off. It was
filled with RTV, but that also scrapes off.
Not recommended for the casual tinkerer, but it -can- be done.. at least
on mine anyway. Had to have it for the Holiday trip...

Remember that Pfranc connectors were one available for the Garmin GPS. I
am guessing they should still be out there. Very inexpensive and good
service.

THe only one. The APRS SPEC standard using the "complete" format.

Not that I know of...
