Yes! The beacon will contain only the telemetry info but you can set it to
beacon at timed intervals.
>2) Is adding the resistors neccesary for the KPC3+ to read correct voltage?
>If so, exactly where should they be added?
Yes it is unless you are useing a voltage less then 5v. The way it works is
the telemetry reads from 0-5v and breakes it down so that 0 = 0 and 5 = 255
I think. Most digies need 12v so you add the resister to drop the voltage
down to between 0-5v I think they say to use a 10k resister so that
thetelemetry reading should be 1.2volts this is what you will see in the
packet being sent. Then on the recieving end you will need to multiply the
telemetry reading by 10 to get 12volts again. UIview has the ability to
enter in the equation to read the telemetry I don't know about the other
flavors of APRS software.
Hope this helps

I remember hearing that BMW was going to introduce a helmet-mounted heads up
display. Has anyone seen this? Any chance of hacking it for APRS use?
I've got a display made (I think) by the same company that I was trying to
hack for paraglider instrumentation. It's got a limited set of fixed LCD
segments, though, and can't display much information. Never got it properly
modified though - my anisotropic conductive film doesn't work for such a
fine conductor pitch.

I believe BMW equipped some of it's Formula-One race car helmets with an
experimental and very specialized (read very expensive) HUD last
season. I don't think they have any plans on releasing the technology to
the general public.
In the same vein...
Kenwood is making a HUD for some of their Excelon and D-mask automobile
hi-fi products. Properly equipped it will display heading and voltage
information.
http://www.kenwoodusa.com/product/product.jsp?productId=669
I don't think it displays RDS messages though. And I have no idea if it
works with the KTC-WB100 (WX receiver) module.
I used to have a Chrysler LeBaron convertible with the "Star Wars"
dashboard and it spoke about a dozen different warning messages. A friend
of my had a talking Datsun 200SX (which I believe was mechanical, like an
old see-n-say). Neither talking cars or electronic displays seemed to
hold the public's or car maker's interests. I have a feeling HUD will
probably be relegated to the gimmick category, like GM Hood Tach's of the
60's...

It's called big business, somebody has found a way to make buck$ off
taxpayer funded data streams. It works on the same principal as Public
Broadcasting being forced to scramble their signals so the cable companys
could charge viewers to watch taxpayer funded programming.
Where there is a potential buck, there will always be someone trying to
wedge themselves between your buck$ and your freedoms.

Hi Paul,
You've got a couple of approaches. Both assume you have HyperTerminal
configured to talk to the right COM port.
1) Reset the TNC's memory, by completely powering down the PC, and
disconnecting the memory backup battery jumper for about 3 minutes. I
don't recall the reference designator for that jumper, but its located
right next to the "watch" battery on the PCB-88 PC board. Reinstall the
jumper, if you want the TNC to retain settings during times when the
computer is powered down. Boot the computer, start HyperTerminal, set
the COM port settings to the desired baud rate (300-19200 baud), with
8-bit, no-parity, 1 stop-bit. Make sure you close the COM (hang up the
phone) before you change the settings, otherwise they don't "take".
Then open the COM port, and type an asterisk (*) character. You may see
some garbage characters prior to typing the *, which is the TNC, telling
you to type the *, generated at a 1200 baud. You don't have to use
1200, but you do have to type the asterisk. As soon as you do, you
should see the PK-88 signon banner, followed by the CMD: prompt.
2) Try the following, at each baud rate, with both 8-bit, no-parity,
and 7-bit, even parity:
Type exactly 3 "Control-C" characters, within 1 second, then wait for 2
seconds. The easiest way it to hold the Control key while tapping the
"C" key quickly 3 times. When you're successful, you'll end up at a
CMD: prompt, and you can go on from there.
If you elect to try technique 2 first, and it fails (though it usually
doesn't) go back to plan 1. If plan 1 fails, you either don't have the
right COM port configured, have a conflict with an existing COM port, or
have a broken PCB-88.
Hope that helps!

I remember some converations about this. I didn't think it was helmet
mounted. I seem to remember it was projected just above the instrument
panel. Even if it were ever released to the general public, it probably
would never be in the helmet. BMW won't even import the System 4 Helmet
to the US because of our idiotic liability/tort laws. No way would they
ever import a helmet like that.

BMW develops head-up display for Ralf Schumacher's helmet
MUNICH, GERMANY, August 13, 2002 (BMW Group) - In the run-up to the
Hungarian Grand Prix, the BMW Technology Office takes the wraps off an
innovative Formula One product. A miniature head-up display system in the
size of 6x8 millimeters integrated in Ralf Schumacher's helmet will enable
a wide range of information and messages to be relayed to the driver. With
this "visual information window" BMW is setting new standards for safety in
Formula One. It means racing drivers can register visual information while
still paying full attention to their driving...
(SNIP)
This pioneering technology opens up an entirely new channel of
communication between the pits and the driver. A module integrated in the
helmet stores various messages and images in a data set, which can be
called up from the pits and displayed to the driver. The mini head-up
display projects the relevant "transparent" image through the visor on a
level with the front of the car. The driver registers the information
without being distracted from what is happening on the track...
