Here Here!
I found this very disturbing as well, and i thought that
it showed baltant disregard for the band plan. 146.52
is a major simplex thorofare here in CT and a beacon
would be bombed in short order. It took a load of griping
for me to get the local foxhunters (whom i now "represent")
to get off .52.
Any op's confirm the existence of this thing???

Subject says it all, pretty much. I am in process of getting Technician+, and
could use some help/advice setting up shack/antenna system, etc. Although I
commute to Houston everyday, I would rather get help from a little closer to
home. (FWIW I actually live closer to College Station/Bryan than to Houston.)

Every time I hear about this I have to chuckle, as if these car
manufacturers think that outside RF somehow stops at the boundary of
their vehicle.
If the computer is so prone to damage from large RF fields and installing
a radio in your car may cause damage, according to the manufacturer, tell
the manufacturer that you're not going to purchase the car. Tell them
"gee, I wouldn't want to have my computer fried by some CB radio operator
in the car next to me running an illegal 1000 watt amplifier." See how
quick they change their story...

It's not a problem with GM products. They even publish a nice pamphlet
describing how you ought to go about installing the radio for least
interference. GM has provided vehicles for mobile communications
activities for as long as I can remember and doesn't want to loose that
business.

I recently acquired an Icom IC-28h that puts out 45 watts at high power.
Nice rig. I think I've fallen in love with mine. :-)
BTW I'm looking at the 94 Accord, Mazda 626, Mitsubishi Gallant, Taurus,
Subaru Legacy, and Camry.
Ask your salesperson for hard proof that the installation will be okay.
I've heard that installing a mobile radio voids the warranty on some
manufacturers vehicles.
I have a hard time believing that it'll be a problem, but this is the place
to ask. Please respond directly via e-mail. Thanks.
Okay. The rest of you folks please pretend you didn't read this. :-)

See if they'll let you test drive the vehicle over the weekend. Put all
the gear you're going to use into the vehicle, put up mag mount or trunk
mount antennas, and QSO-away at full power driving around your neighborhood.
If the vehicle dies, catch a ride home, pull out the gear, call the dealer
and tell him they've got a DOA vehicle to pick up! Just a sly suggestion,
a friend did this before he picked up his Bronco II and it worked fine,
so he finalized the deal.

David,
I not only had my 2m rig in the car but I have 155Mhz radio in my car
scanner under the dash and Green Light on my roof (Volunteer Paramedic).
None of these devices voided my warantee or ruined my cars computer.
Yours cars computer get more sh*t from that engine then it ever will from
your 2m rig.
So relax and enjoy your car and your hobby.

SYNOPSIS OF ACTIVITY
--------------------
Solar activity was very low. A Type II sweep was
reported by the Sagamore Hill and San Vito observatories at
31/1029Z. Shock velocity was estimated at 1500 km/sec. No
x-ray or optical correlation was indicated with this sweep.
Solar activity forecast: solar activity is expected to be
very low.
The geomagnetic field has been at mostly quiet to
unsettled levels for the past 24 hours. The GT 2 MeV energetic
electron flux was mostly normal to moderate. A brief period of
high flux readings was recorded early in the period from
30/2100Z to 30/2400Z.
Geophysical activity forecast: the geomagnetic field is
expected to be mostly quiet to unsettled for the next three
days.

No changes are expected over the next 2 to 3 days, although
there is a slight chance high latitudes may begin to see minor
signal degradation on 03 or 04 August in response to recurrent
geomagnetic activity.

I think it's fair to say that hams *are* more experimentally inclined
than the general population, most of the general population are still
staring at the 12:00 flashing on their VCRs. However, I don't think
hams are much different from the average technoid computer user. Many
hams are hackers (in the original good meaning of the term). They are
going to want either source code, or they're going to disassemble the
binary to see how it works. And they are likely to want to tinker
with the code. Then they'll want to share that knowledge with their
fellows.
Because of the experimental nature of amateur radio, I prefer not
to use commercial software for my amateur activities. That's why
when the Netrom-theNet controversy boiled up I went another way,
using the KA9Q code as switch code. Yeah, it meant a PC on the
mountain, but it gave me more flexibility to experiment. And that's
what it's all about for me.
When I do buy commercial software, I avoid software with copy
protection or restrictive licensing. I'll pay a book price for
useful software whose author treats it like a book in his license
agreement. I won't pay exorbitant prices for buggy software with
no support and lock and key licensing. It seems that most software
marketed in the latter way has fallen by the wayside because others
feel the same way I do. When most software authors complain about
piracy, it's usually just imaginary sales that they are trying to
tally. The ones screaming piracy the loudest probably have software
priced such that they aren't going to get many legitimate sales
anyway. Those with more realistic pricing don't seem to have as
much complaint about piracy, and their sales are larger too.

So, yes, the code test will make a difference. It will give you HF priviledges
that Technicians who have not passed the code test will have.

Yes, it qualifies you for the Tech Plus license which has limited HF
priviledges, including voice on a segment of 10 meters and all of your
current Novice CW segments.

It's a very sore issue, off to policy with you. :-)

The FCC initially said that there wouldn't be a separate license for
Tech with code, just keep your proof you passed a 5 WPM exam forever
and go ahead and use the HF slivers. Now, however, it's reported that
the new computer system at the FCC is allowing them to print Tech Plus
on licenses of those with proof of passing a 5 WPM exam. If you haven't
passed a 5 WPM exam, you're limited to the frequencies above 30 MHz and
don't get the Plus printed on your Tech license.

Oh boy. It is arguable if Ramsey deserves some of the flames hurled
at him. He definitely does not deserve this one!
Look, I interpret what John Ramsey wrote as: Ramsey purposely made the
coils a little larger than neccessary, so that simpletons could tune
the stuff they had built with very little trouble. Had he made the
coils a little smaller, the purchaser would have had to add more turns,
which is much more difficult to do, to achieve equivalent ability
to tune. Thus
