And many car manufacturers actually do testing to certify that their cars
sold to the general public can take the installment of high powered
transceivers and work with customers to resolve any issues that may arise
from those situations they have not anticipated. BMW is not one of
them. Last time I was at the Dayton Hamfest, both Ford and Chrysler had a
very visiable presence there. GM was there, too. BTW, a small number
of hams even got permision to mount transceivers in their leased Saturn EV1's.

Apparently you may be driving that 1965 Chen Jiang motorcycle, but if
you've looked at a motorcycle built in the last 15 years or so, you'll find
fully computerized ignition control, ABS brakes, computerized fuel
injection, etc. Just like a modern car. The last motorcycle I owned was
totally black boxed (FUF'ed as one Honda Tech put it), had no kick starter,
and a water cooled engine complete with a teeny tiny radiator fan. It
seems to me that if the computerized controls of my car may be susceptible
to RF, that a motorycycle, without all that steel shielding, would possibly
be even more susceptible to near-field RF.

Well, since there are only Two (viable) companies left that make police
bikes in the western world (Harley & BMW) that's kind of one of those
statistic non-statistics. Um, what other choice does a police department
have? I seem to recall Kawasaki used to be the prevalent maker of police
motorcycles, but that they fell out of favor due to the fact that the
KZ1000 developed high-speed instabilities that were linked (at least
anecdotally) to the placement of the POLICE BAND TRANSCEIVER on the
bike. Kawasaki still makes an air cooled "Police 1000," but no
department wants to buy them based on past reputation - unfounded or not.
Back in the "good 'ol days" one could always tell in SoCal or Arizona when
a motorcycle cop was in the area (even if you couldn't see him), because
the sound of a "shafty" 1000cc Kawasaki is unmistakable for anything else,
and since they were uncommon to be owned by the general populace...

Well, I'm curious. How well are you able to talk while on the move?
Seems to me, with all the vehicle noise around me on a freeway, I wouldn't
be able to hear a thing? What type mic, headphones do you use? I've
never tapped into the intercomm on my bike ('99 Valk) but I'd guess it's
probably the same as the Gold Wing?
curious,

Just wondering if someone knows where the messages come from that appear as
though they've been sent by UO-14. We have at least one person in the PNW
who regularily receives them on his D700 mobile and has no idea how or why
he's been chosen, but he did say they're a little annoying. They show up as
UO14 directed to his mobile callsign. I've also seen them through Findu as
having been sent to others, though the ones sent to this fellow's call didn't
show up there for some reason. All we can tell from the path is that they
come off tcpip through an I-gate. It sends one of three different Kenwood
D700 message codes, %[52] for HIGH, %[53] for MED, or %[53] for LOW.

Correction to the D700 codes, should have been: %[52] for HIGH, %[53] for
MED, or %[54] for LOW.

I can hear just fine. I have a fairing mounted speaker that can be
'switch selected' and all I have to do is turn down the AM/FM...
The mic is the problem. Wind noise kill it. Even sitting, the 'high
frequency whir' from the motor, as quiet as it is, seems to drive the
thing nuts. VERY difficult to use while moving. The guy I bought
the bike from had a setup with a mic element in the chin-bar of his
helmet and that worked beautiful. And I've heard Honda riders with
the intercom system from Honda wired into their 2M setups. But the
Honda headpiece with the special noise canceling mike is MUCH
more than another radio! Still, unless I can get my system quiet with
regard to the road/wind noise...
In the meantime, that's why I was thinking of maybe hooking it to
the MIC-E and an old Garmin...

I ride my motorcycles all the time, and we ran APRS on the bikes to the
Abilene Hamfest (it was Alton's porta-tinytrak N5PSP-12 that day)
We found that the Garmin bike handlebar mount worked excellent for our eTrex
models (Legend with maps), even at "high speed" (we refuse to state an
actual maximum speed as it may have a tendency to incriminate ourselves...)
Just got my P-Franc e-plugs in to make some custom cables for the Garmin
units.
I have my own little amateur radio website (much neglected, but should have
more time now that I am "single again"). I would be extremely interested in
providing space for APRS on two wheels (bicycle and motorcycle). If folks
would email me content directly, I could have stuff posted in a week or so
from now...
Additionally, I am looking at facing the following daunting tasks in the
near future and would like suggestions:
1. APRS on both my motocycles (basically permanent rather than temporary).
However, for anti-theft, I'd like some ideas.
2. Back-Pack APRS for some upcoming camping trips.
3. Back-Pack APRS-Digi for some upcoming camping trips.
4. Pocket-APRS for my Palm M-500 (cable, etc?)
5. Building/buying 3.3vdc supplies for running the Garmins from bike power
Please send info to me off-list and I will be able to post a summary to the
list. content for two-wheeled APRS should also be sent off-list. Pictures
should be sent in 'high-res' formats so that they will degrade gracefully
when 'web-ized'. Each pic should have a caption, date, who's-who in the
photo, a 3-4 sentence paragraph (or more!), and any additional info such as
web reference pages, etc. Just send in email. Of course if there is a lot
of content you could mail a CD. Of particular interest would be
installation tips, I would think.
