Not to mention that if the machine you wish to use this on is an asset
of an organization which has locked down policies on its hardware (as
any IT Dept. should in a corporate or similar environment) you will
probably NOT be able to load the driver or install new software if your
user profile does not allow it. If Bob (APR) is hoping to be able to use
this plug-n-pray on the campus where he works, he may have problems with
this unfortunately (or fortunately if you look at it from the IT
Managers viewpoint).

INSTALL THESE THINGS IN OTHER PEOPLES' WIN98 MACHINES AT YOUR OWN RISK!!
You are causing alien drivers to be added to someone else's machine,
thereby unavoidably meddling with, and changing their Windows

Subject: PCsat fully operational for Holidays

PCsat (NO44) is now fully operational.
She has a downlink bulletin on 144.39 over the USA so that when you
see a packet from it on the terrestrial network, you konw you can QSY
your mobile to 145.825(up and down) and work her with no changes to your
terrestrial mobile operations.
She digi's UI packets via RELAY, WIDE, and PCSAT-1. She is in view in the
morning and evening commutes in Northern Latitudes as shown below.
Sats 06 07 08 09 10 11 12 13 14 15 16 17 18 19 20 21 22 23 00 01 02 03

ISS ******* **** ******* **********
NO44 ************* * ************ **
NO45 ********** **** ************ *
This table is local time at all mid northern latitudes. At higher
latitudes (say 50), then she is in view for 6 passes in a row between
about 0900 to 1700 or so.. Also, Sapphire is in the same orbit but about
30 minutes behind. Sapphire (NO45) digipeater is harder:
1) Uplink is on 145.945
2) Downlink is much weaker and on 437.105 down to 437.090 during pass
3) DIGI call is via KE6QMD

I'd like to bid on those two... ;-)

Once an open-source program has been out there for a bit, there are
usually contributions from others put into the main code. Unless
you get the buy-in from those other contributors, you can't change
the license on the whole thing. There have been open-source
projects that have had to go back and try to find all of the
contributors, and it can be a daunting task.
The Xastir project was started by one individual, and currently has
twelve listed developers. Over the last several years has received
patches and new code from probably 50+ people. It's GPL'ed. To
change the license to anything else we'd have to find those 50+
people and get permission from each, else back out their changes and
rewrite them from scratch.
I release things under both BSD and GPL. Depends on what I'm doing
and why. I suspect John will have to think long and hard about how
to do this without causing problems later. It's not easy,
particularly when you're trying to make a profit (which I support by
the way). When your goal is just to get the code out there and
available, the choices are a bit easier.

My question:
Can I presume that when the ctcss 100 is engaged
on both sides (xmit and rx), that the only APRS traffic that will make
it into my radio (TMD-700) are the ones from stations also using the 100
ctcss tone? In other words local digipeaters and such that receive my
signal will not be able to send back due to the 100 hx tone on my
receive side. I get a bit thick skulled at times. 73. Keith.

I caught one on my d-700 from 2400 miles away (I'm inAlabama)in the same
time frame. I'm gonna look up the path and see how I got it. I might
send him a QSL just for fun!! I love this hobby!! Keith

Hi Sean,
The primary issue, is what is your product. IBMs product is the computer
systems, and the consulting, and the software systems that they sell, which
use Linux as an OS platform. The fact that Linux is GPL does not obligate them
to provide their technicians for free. Nor does it obligate them to give the
hardware away.
GPL on the base opentrac software implementation would mean that if I then
went out and created a new radio that used opentrac, and which had all kinds
of fancy features for graphical display, that I would have to give the
software that was related to that opentrac development back to Scott. That
software would be the defining attribute of my product. It would be the way
that I added value to the system.
Scott has a choice about where he wants to be in this picture. It is his
choice. But, I am suggesting that there is such a small amount of opentrac
existing today, that is that core software, that puting the GPL on it would
create some issues.
1. Everyone would have to recreate that software and possibly get it
wrong, leading to the kind of incompatibilities that we have in the TH-D7.
We could even get to the point of having incompatible fixes to those
incompatibilities.
2. Having to create the software is an investment that might be the
straw that breaks the camels back and some companies would never get
started.
3. Vendors would not really feel that they had a differentiating
factor because this is a largely software defined application. If they had
to share all of their work with the 'world', competitors would abound and
noone would have enough marketshare to feel that they could make a profit.
4. Evolution of any software system is paramount on everyone feeling
like the software development is open to their contributions. Where the
platform can be expanded or extended, I think it would be great to let
people decide what they want to give back. This allows the community to
place expectations on the commercial implementations through market forces
which are decisive.
Just my thoughts...
