Subject: [aprssig] KAM 98 as a fill in digi?
Can a KAM 98 be configured to operate as a fill-in VHF digi? I still
haven't had a chance to fix the normal KPC3+ that sits on the digi but I do
have a KAM 98 that I could temporarily press into service.

Perhaps I should retract a bit - I haven't tried the pfranc one. The eTrex
one that I bought slips out almost as if it is lubricated, however.

Subject: [aprssig] RE: Stupid D7 tricks
Oh, I completely understand what I did. I did it on purpose and knew what
the outcome would be. "Stupid D7 tricks" is a little twist on the phrase
"Stupid pet tricks" which is a segment of the David Letterman show here in
the US.
I wasn't trying to imply that I didn't know what was going on, just that I
decided to implement a built-in feature in a rather amusing but useless way
-- much like stupid pet tricks are amusing but useless.
Anyway, doing this does not work well because most consumer GPS receivers
send out four or five NEMA sentences every second. Since the internal
storage buffer is only queried at one second intervals (the maximum rate
available through the LTMON command) the end result is either the same
sentence type making it through or, as was the case of my GPS receiver, two
sentences alternating back and forth at times. The actual results are
unpredictable and completely depend on the timing between enabling GPS
receiver data collection, enabling the LTMON command, and any latencies in
the TNC or GPS receiver.
It would be more useful if there was a way to pass data in the other
direction (PC port to GPS port) but I don't think there's a chance of that
unless hidden deep within the firmware of the TNC there exists a command
(even a low level bit-banging command) to do so.

Subject: [aprssig] Sky Ccommand...
In addition to doing APRS, and Voice Alert, with my D700 mobile and also
seeing local repeaters on the front panel, I now wanna play with the
TS-2000 HF rig at work with my D700 mobile via Skycommand.
So before leaving the office, I set up the HF rig and my mobile for sky
command and had my son drive home while I played with the HF rig remotely.
Soon I had lots of questions:
1) does it ever time out? I ran out of range, but the link stayed up. I
had to turn around to get back in range to turn it off again.
2) What does the #1 ON/OFF command do? I saw no change.
3) Is there anyway for others to share my rig, or do we all just use the
same generic call?
4) Is there anyway for us to use the VHF channel as a back-channel for
voice between multiple operators while only one of us is logged on the HF
rig via SKY command.
5) Is there anyway for the group to decode and see the HF frequency while I
am commanding. Mayb ebe in APRS mode and hit PMON to monitor the packet
data? Is the data human readable?
6) what is a safe power level for the TS-2000 2m TX since it is key down
100% of the time.
7) How do you remotely band change? Just have multiple memories?
8) how can you edit out an extra character in a 4 or 5 character call?
There is no SPACE character and no DEL button that I can find.
I want to set up this TS-2000 for the student community at the school so
everyone can use it, so that is why I am looking at these ideas.
Has anyone decoded the packet exchange for all commands? This should be
easy to add to any APRS client. This legalization of sky command could not
have come at a better time for our radio club. The Naval Academy again has
the radio club on the chopping block and is determined to clear the roof of
our "unsightly" antennas. So with SKY command, we could just put the
TS-2000 across the river and let the students access it from their D7 HT's.

Subject: [aprssig] Consulting
Anyone doing APRS consulting in upstate New York?
I have an email from a police chief that want to use APRS, they already
have laptops with TCP connections in the cars, sounds like it will be a
matter of setting up an APRS IS hub or two, installing the software, doing
a few custom maps, and of course training.
He is looking for a pro, not someone interesting in seeing their hobby put
to use. If you don't have a real business including liability insurance,
they don't want you...

Didn't the FCC rule SkyCommand illegal in the US?
