Hello folks,
    Does anyone know where I can get information
on the L2 program used by Baycom. This is the TSR program that
is used to interface the Baycom terminal program with the hardware modem.
I am interested in cpu registers etc. that are used to communicate with
this L2 driver.  Any info/sources would be appreciated.

My '94 Chevy Lumina Euro seems OK for HF; I'd planted my Kenwood
TS-140 on the passenger seat the other day, and had NO problems.
75W out on 20M thru the cigarette lighter; OK, large capacitor and
ferrite torroid on power lines, left over from my '88 Grand Am whose
"Driver Information Center" didn't like the 20M band :-).  Couldn't
even find the "birdies" from the Engine Control Module's uP!

The only discernable "noise" is a small bit of hash from the fuel pump,
and a lot of hash when raising/lowering the power windows.  I suspect
a simple LCL Pi filter on the fuel pump harness (near the fuel pump)
would take out the noise, but so does the noise blanker on the radio.


BTW:
Not to make this a big sale pitch for GM, but we do a LOT of RFI
testing on our cars to make sure that they neither corrupt nor get
corrupted by ham rigs.  Stop by the GM booth at the Dayton HamVention
and we can talk some more . . .

My father uses a TS 50 and an IC901 in his taurus.  only noise is slight alt whine
on the 901.  Only effect caused by xmitting is changing the speed of the key-in-ignition
chime when xmitting on 440.  He's happy with car.

Of course I hold onto my old 71 VW bus.  Point ignition, generator, etc. all waay in the
back, entire body grounded, lotsa room for rigs, etc.  I'd hate to lose that car!

No facny stuff required by the computer.

Subject: Q:Remote PC Control for Radio/TV receivers/scanners ?
To: [e-mail]

Hello Netpeople,

I was wondering if by any chance there has evolved some sort of
Personal Computer remote control standard for radio and TV equipment,
like e.g. the GPIB interface for analogue measurement equipment 15 or
more years back.
I know nowadays you can buy TV-receiver cards for the PC which may
or may not be sufficiently shielded, what I do know is that with
soundcards the noise situation can't possibly be bettered without
making the product substantially more expensive and I guess this
holds for anything inside a PC processing HF and higher frequency
analogue signals.
Any radio & TV sets out there with GPIB or its successor ?

Thanks in advance,                Bob.

For a wild shot, could there have been a Piezo-electric (sp?) effect taking

combustion causing a piezo-electric discharge)?

This was a *real* mechanical injection diesel engine. With *all* electrical
systems disconnected, it still made the pseudo-ignition noise. The best
guess we could come up with was that the plasma formed by combustion was
somehow shock exciting something and causing it to radiate. We considered
static discharges due to the rotating machinery, but we bonded *everything*,
including finger stock on the crank and cam, and on the injection pump
cam, and we put anti-static brushes on the clutch, all without making it
go away. So I don't think that was it. It would sit there at idle in the
shop and tear up every radio in the place with absolutely *no* electrical
equipment operating on the vehicle. A real puzzle.

                                                        ! WRONG !

We've been building diesel engine controllers for many many years.

In fact, we've got an engine controller for LP-fueled fork-lifts!

And we've got a controller for marine applications; one of them even
got submerged (with the boat) in salt-water for 10 weeks, and after
they dredged-out the boat (and cleaned-up the engine) the engine
started on the 1st-crank with THAT controller.  But I digress.

There are several diesel models with computers controlling the
electronically controlled transmissions!

And what about the instrument cluster, CD player/Radio, etc.?

The dealers don't care, wave money in their faces and they'll order
anything in their book.
