That's pretty cool. 15 kW = ~20 horsepower. I think the Prius has a 78
horsepower engine, so that's about 25% efficiency. Sounds decent, anyway -
anyone know how that compares to a 15 kW diesel generator?

Thanks Scott. If you check at home and that's the correct one, please drop
me a line. I remember several years ago i bought a lot of the wrong ones
(5.x OD) by mistake and had to swap them out. Who knows.. the state that
Ratshack is in these days they probably don't even carry them anymore!
After this weekend... I'll probably get some pre-mades from you. Have lots
of folks around here getting trackers ready...

Subject: Re: [aprssig] KPC3 power connector size
Scott is right. It's 2.1 x 5.5mm. Outer conductor is ground and inner is
positive. Mouser and Digi-Key have niced molded pigtails for < $2 each.

Subject: [aprssig] Voice repeater objects
Voice Repeater Objects:
Now, as Alabama has begun adding Voice Repeater Objects to all of its 15
UIDIGI ROM digipeaters (thanks tim!), we have a lot of good feedback and
have improved the text associated with the display formats. The "lines"
refer to how the voice repeater object looks when received on a D7 or D700
10x10x8 display format. Here are some examples.
1st line: is the FFF.FFF FREQUENCY (in place of callsign)
2nd line: (actually beginning of Object text)
T123 R45mi - Combines PL and Range on one line.
D234 R45mi - Combines DCS code and Range on one line.
N45, S15mi - No tone with different ranges N/S or E/W
3rd Line: (begins w space if previous line uses 10
Net 9pm W - if it has regular nets worthy of note
Mtg 1st M - if it has regular meetings
144.875in - optional for a non stndard input
4th Line: (The first 8 bytes will show on the D700, more will show on PC
clients...
Also the DUPE issue on the APRS-IS has been resolved since we have these
OBJECT NAME Formats:
FFF.FFF-x - where x is one of 62 characters (A-z or 0-9)
FFF.FF+xy - where xy is one of over 3600 combinations
The +/- indicate offset.
With all these options, surely all of the 146.94 repeaters can find a
unique combination. And the way I see it, the first one that gets on the
air, the better the choice. Though it would be nice to negotiate if there
are conflicts. Now that these all appear on the APRS-IS, it is easy to see
what is already in use. Just http://MAP.FINDU.COM/146.94* to see which ones
are on the air!
So all this is on the updated LOCAL-INFO-INITIATIVE web site:
http://www.ew.usna.edu/~bruninga/localinfo.html
If you are going to get your locally recommended best travelers voice
repeater object on the APRS map, please do it before the big Dayton
Pilgrimage!
Thanks,
Bob, WB4APR

Guys, does this sound like right up Bob Bruninga's alley? Hotwheels
(mattel) makes a radar gun sold at walmart and the like for about $20 to
$30. Wouldn't it be cool to hack it to get the doppler shift out as a 0-5v
voltage and have a PIC (ahem basic stamp, right?) measure the speed of
traffic. Then drop them on the side of the road at pinch points and
transmit the traffic on aprs!

I would not consider the position report to be "advertising". It is a
service, just like putting the local EOC or local VOICE repeater on the
map.
But I think we all agree that the advertising TEXT that was posted is
clearly across the line.
But if McDonalds (having nothing to do with HAM radio ) began putting APRS
objects on the map, I would agree completely that that is clearly across
the line and is advertising. But if I am parked with my mobile
communications shelter in the parking lot of a GOLDEN CORRAL who has
offered a presentation opportunity on ARMAD (Amateur Radio Military
Appreciation day), then again, I would have no problem at all with putting
the GOLDEN CORRAL on the map for that demo...
My 2 cents.

Exactly! That was the APRS plan back in 1996 or so when we first
introduced the APRS sign-post SYMBOL. To show the speed of traffic past a
point. I never had time to develop a good sensor. Google APRS TRAFFIC.TXT

Sadly, the days of being able to drop homemade electronic packages by the
side of the road are over!

Perhaps people would leave it alone if we taped some D cells together
painted red and had some curly wires sticking out? Reminds me of a bomb
threat at a local hardware store in Sumter SC. Someone in the parking lot
saw what appeared to be dynamite, wires and a blinking LED light under an
SUV. After evacuating an entire block and closing the hardware store we
learned that the guy's wife thought he was having an affair and had
installed a GPS tracker under his car.
