I have a kpc3+ that seems to be brain injured...hard resets have only
resulted in text that almost readable! instead of ve7whk it shows
ve7whs*##.and all sorts of other confused characters!!
Any one have any ideas!
The unit has been running aprs effiecintly for some time with no
problems till now.

Sounds like a cable gone bad. Try a different cable - preferably on a
different computer.

Just this moment I see you in Ft Stockton going down I-10.
Was just talking to KD5MHM on the phone 5 minutes before that, somewhere
east of here on I-20 headed for Colorado City. Seems the KE5PL-1 digi must
have quit working about 6 hours ago since no one seems to be getting digied
or gated in Midland at the moment. KE5PL-4 in Big Spring is getting digied
via K5WTC in Lamesa, W5CDM-1 near Goldsmith, and finally gated by KD5HAD in
Odessa.
KD5MHM-9 still shows up at the PBARC Field Day site where we did the APRS
demonstration Sunday.

Reminds me, every 4 minutes or less on a busy interstate you will pass by
another ham going the opposite direction. This shows the potential power
of APRS, and of the two features of APRS Voice-Alert that I talk about so
much.
Voice alert assures that they know what freq to call you on, and 2) your
PL100 packets are a radar alerting them to your presence.
This post is nothing new, but last time I posted it, I "estimated" 5
minutes. Today, Driving home from a boring meeting, I actually counted
cars and got about 80 per minute that I passed. With the USA population
(over 10 years old) at 240 Million and this week's Field Day PR showing
our numbers at 800,000 gave me the new calculation.
Your interstates may vary. I'd say this one qualified as busy, but
operating above the speed limit with good flow. Thats one HAM every 4
miles. Of course, these are just statistics.
But just something to think about.
Might be worth having a mobile rig in the car... and trying out Voice
Alert (on the open road)...

Where I live, that's more like 4 hours, to 4 days.
I think I passed near two, on my trip from Muncie IN to Moultrie Ga., but
none on my route.

1 in 350 is a ham in the US (280M/800k). No contest. I'm not sure though
that therefor 1 in 350 vehicles will be occupied by a hamradio operator.
Of course not every ham ham is allowed to control a vehicle (kids, for
instance), and not every ham is allowed to install a radio in the
vehicle he or she is driving (company car for instance). Only a limited
number of hams will actually own a mobile rig. Even fewer will be
running mobile APRS. Even less hams will be running a configuration
capable of VA. The 1 in 4 minutes probably will drop to 1 in many hours.
Just statistics.
I'd carry a repeater directory, as I still think Voice Alert is bad
amateur radio practice.

My numbers were for population over 10 when most kids get their license.
In the summer on long interstates they often travel with their parents.
>Only a limited number of hams will actually own a mobile rig.
Thats part of my point. If they knew the numbers were so high, maybe
they would. And expecially if they knew they could talk to another mobile
nearby instead of the same vacant unused voice repeaters that they have to
thumb through a book to find...
>Even fewer will be running mobile APRS.
Again, part of my point. If they knew how powerful it was or even
without APRS if they knew that other APRS mobiles were running voice
alert, then they might listen for them...
>Even less hams will be running a configuration capable of VA.
Thus my post. To encoureage them...
>The 1 in 4 minutes probably will drop to 1 in many hours.
>Just statistics.
Yep, thats why we need to raise the education level about this powerful
feature, APRS in general, and the joy of sharing the hobby with your
fellow travelers...
>I'd carry a repeater directory, as I still think Voice Alert is bad
>amateur radio practice.
Three points here. Transmitting PL100 on your existing packets cannot be
bad amateur practice. A mobile APRS operator is already transmitting
packets, so whether he has PL on or off is no difference.
That is the RADAR half of Voice Alert. It is a non issue.
If you are concerned about being called on 144.39 (the incoming side
of the Voice Alert feature) then simply put any other voice
frequency in your Status text and let people call you there.
Remember, that is the #1 goal here. To announce where you are listening.
Whether it is 144.39 or not.
And one more thing about the driving public. I would tend to say that the
age of most active hams is just about a perfect match with the age
variation of drivers. In fact, I would argue that those people that are
on the road a lot are probaly a higher proportion of HAMS then average.
All you gotta know is their frequency...
Summer is a good time to travel...

I can't help but wonder about the long threads that spoke of the need to
offload APRS traffic to a faster backbone because of congestion on 144.39.
Is having voice traffic on the APRS frequency really congruant with that
line of thought? After all...all of the WIDE's in range would hear that
voice conversation's carriers...further complicating the whole picture.
On the other hand...it is a fascinating proposal...one that I'm considering
in the CU2QSO (APRS on VHF Contesting Steroids) world on 147.585 MHz, where
Rover Radar is the whole idea and digipeating is not used. Since the idea
is to enhance more traditional communication...CU2QSO is a good place to
really exploit it all.
