You want to be careful what kind of glass you use. Coleman lantern globes
are heat-resistant, so are a good choice for a tube chimney.
They are just the right size, too!

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 . . .

Without commenting on their suitability for radio (and I know at least
one person who has had a large HF station in a Jeep), in this part of
the country (Northern New England) used Jeeps have been known as cars
to avoid due to the amount of rust they develop. This is not an issue
in the southwest, and I doubt they use much salt on the roads in the
Atlanta area. Your mileage (sorry) may vary.

This is sorta like the burst we've seen in amateur radio with the Technician

Big jump of new people and not enough "old guys" running around to do the
introductions....what it means is that we get to find out if "netiquette" is
up to the task. if it works well for most it will continue pretty much the
way it is, if it's not, it will "change" and either improve or degrade.
It's like the rear guard still fighting the battles over the use of the word
"destinated" - usually by replacing it with something a lot more wordy that
means "arrived".

SYNOPSIS OF ACTIVITY
--------------------
Solar activity was very low. No activity beyond a B4/SF
flare in Region 7690 (S15W68) occurred.
Solar activity forecast: solar activity is expected to be
very low to low. Region 7688 (N18E33) has the best chance for
C-class activity.
The geomagnetic field has been at unsettled to active
levels for the past 24 hours. High latitude stations reported
occassional minor storm levels. Energetic electron fluxes
(GT 2 MeV) have receded to moderate levels.
Geophysical activity forecast: the geomagnetic field is
expected to be mostly unsettled for the entire forecast period.
High latitude stations may still experience active levels for
the next 24 hours.
Event probabilities 14 mar-16 mar

HF propagation conditions were below-normal, but slowly
improving over the high and polar latitude regions. Middle
latitude paths were returning to near-normal values today.
High and polar latitudes should return to near-normal values
(with sporadic periods of minor night-sector signal
degradation) by about 15 or 16 March.

When you include the space between elements, the dash/dot ratio is 2:
Dot Dash
XXXXX XXXXXXXXXXXXXXX XXXXXetc.........
<-1-><-1-><------3------><-1->
<----2---><--------4--------->
A string of dots has twice the number of elements per second as a

and dahs as half notes. No triplets required!

There's a typo in the above equation -- the units don't work out.
(Seconds don't equal coulombs * coulombs/sec) Also, to convert from
seconds to hours you divide by 3600. I think the equation should be:

Greetings...you'll have to excuse my lack of knowledge when it
comes to using FTP procedures....haven't been at this long....using
FTP I login to FUNE.FI, no problem there...once I find a .ZIP file
I want I ask it to GET the file... again no problem, the program is
sent to my local mainframe...I log off of the FTP address and go to
the local mainframe and ask to send...I receive the file
as a .ZIP but cannot UNZip it...I ALWAYS get "WARNING!" file fails
CRC check or "has bad table"....on the local mainframe we have to
use KERMIT to transfer files...or at least that is what I was
told....like I said, I'm new at this so please exucuse my lack of
knowledge associated with using FTP procedures...I thank you in
advance for any information I might receive. <snip>
You need to transfer the file as a binary, to do this, invoke the "bin"
(binary) command before the "get" command. If you are transferring several
binary files, you only need to issue the "bin" command before the first
one, it is a toggle to binary mode. Otherwise, the default file transfer
mode is ascii. That should fix your problem. You may also want to make sure
you have pkunzip 2.04 rather than an earlier version, since you can not
unzip a file zipped with 2.04 with an old unzip.

Actually it could be done. You'll need some sort of card that will allow
you to control relays, etc. They sell them in some of the engineering
magazines for roughly $200.
The software end wouldn't be too complicated either, and with a hard drive
it'd be one kick-butt controller. Hell.. think of the mods you could make!

Perhaps some of you can help me with a couple of projects we have in our
Biodynamics lab. We have need for transmitting (one way) some analog and
digital signals to a nearby PC for recording and later processing, but
need a wireless link. On one project, the maximum distance is around 30'
(mobile cats walking around) and the other, around 1 mile (instrumenting
Olympic cyclists).
Can you recommend vendors that offer kits, modules or systems that
enable the wireless transmission of analog and digital signals over small
distances? More specifically, we would like to remote 4+ x 2000 hz,
analog (12 bit range) signals to a PC. I could ADC and convert to high
speed serial locally then transmit a digital serial stream. I am familiar
with EE cktry so am not afraid to build peripherial equipment but need
help with the basic RF link.
Your help is most appreciated. Since I don't often read newsgroups, I
would appreciate any information mailed to me @

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.?

Yea, but who wants to be seen in an LTD or Caprice - dead or alive?

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

combustion causing a piezo-electric discharge)?

A large part of the problem is that these services offer "free trial
memberships" and allow posting - thus you get people who go out and buy
a modem, get on-line, post a blatantly offensive advertisement to
non-commercial groups, and then go away, having used up their free
trial. Not much we can do about that person; he's gone.
We have a similar problem here at the University each year as freshmen
get their new computer access. Luckily more and more of them have some
experience with computer networks when they arrive, but even so, that
experience was gained at the expense of someone somewhere.
AOL, Delphi, Prodigy, and so on are just the latest instances of the
newbie problem. Perhaps because the users of those systems are PAYING
for their access it's harder to say to them "no posting until you know
what you're doing!".
