But Bob,
don't you have GREP for Windows installed? That would be the first thing
to do to overcome your Unix Withdrawal Symptoms, wouldn't it? :)

Subject: AX.25 PID assignment
From: Miller Scott Contr 30SCS/FTI <Scott.Miller@vandenberg.af.mil>

X-Message-Number: 15
The AX.25 spec states that creators of layer 3 protocols should contact the
ARRL for suggested PID encodings. So far, I haven't had any luck with ARRL
contacts. Does anyone know who I might contact to coordinate assignment of
a PID? Or at the very least, is there a more comprehensive list of PIDs in
use than the one in the spec, so I can choose one that's not already in use?
Thanks...

Good points but the TH-D7 will work with TXD's in the order of 60-80ms at
1200 baud (Bill Diaz tests). So.... the TH-D7 with a default TXD of 500ms
wastes 500-(60-80) or 420-440ms, not 300ms. Literally cuts the channel
capacity in half.
BTW, I've never seen any explanation from Kenwood about this, which is odd
since the TH-D7 is one of the faster 1200 baud radios on the market.
Strange they would hobble it with such a long TXD.

The TH-D7(G) has a user command that allows varying the TXD in 100 ms
increments. I wish they had smaller steps, but that's certainly adequate to
allow for cutting back the TXD. This was one of the oversights in the
original D7 that was corrected with the (G) upgrade.
How many folks with a D7(G) that have actually cut the time down to
something more sane like 200 or 300 ms is a good question...

After a snow storm rolled through here yesterday it had me thinking
about a desktop background app I used back in my OS/2 days that simply
grabbed an nexrad image and used it for a background image. Well after
some thought and a little trail-n-error I through together this short
script that hacked together an image that was suitable for KDE to
"rotate" as a background image. I just call it from a cron and now I
get a relatively recent radar image.
If you plan on using it you will have to modify some of the paths within
the script as well as the image[s] you grab from noaa.

But alas, the problem is that even though it is not transmitting, it is not
listening either. In that 200ms, my rig in the vicinity of the long tx
delay station could key up and transmit only to be clobbered 200ms later by
your slow rig which started to transmit long before my rig did.

p.s. You Dutch amaze me with your command of the English language. You
speak better and your grammar is better than many locals here! Bravo!

Being a brand new TH-D7 owner, I am looking for all info on this rig. I just
turned my TXD down to 200 ms. I assume this is a good thing.

That's a good thing. Your packets are now taking about half the transmit
time they did before. Keep an eye on how well it's working. If you find
you're not getting out like you used to - then there are probably
digipeaters in your area that can't handle the 200 ms time. If that
happens, increase it to 300 ms and see if that works better. If you find
it's still not working and you have to go to 400 ms - get the digipeaters
replaced. :-)
The D7(G) is a great HT. Enjoy!
