  I have spent a good bit of time trying to produce a map of the
packet network that I can reach.  So far this extends across East Texas,
all of Louisiana, and parts of Arkansas, Kansas, and Oklahoma, and Mexico.
(Yes, Mexico, not New Mexico.)  Is anyone out there interested in seeing
this information?  I should note that the packet network changes at a rate
that makes the Internet look slow, so there can be no guarantee that it still
matches my information.  It changes faster than I can update, and in some
cases the changes block my access to whole segments of the network.
  The information is in a paper notebook, not electronic form, so it
will require some effort to type in and reformat.  Don't expect to see
it next week.
  My biggest problem/frustration to date has been my inability to find
a VHF path between NE Texas and SW Arkansas.  Actually, the dividing line
is inside Texas.  I am forced to go through a very busy HF link in order
to access much of the net.  In some cases I can work nodes on both sides
of the "invisible barrier" that are only a few miles apart, but they do not
talk to each other.
  If anyone out there can get from TXK (Texarkana) to LFKN (Lufkin) without
HF links, I would appreciate a quick summary of the path used.

Instead of arguing about angels dancing on pinheads, why not TEST it?

Nearly all colour monitors have enough "radiated" magnetic field from
their sweep circuits to be heard if the phone's receiver and/or network
coil is close enough to them.  A few have adequate magnetic shielding or
are designed to confine the wasted magnetic fields.

Here's how to figure it out for your monitor:

Just pick up your phone, dial a digit to break dialtone, and with the
receiver to your ear, lean towards the monitor.  When you hear AC hum
in the receiver, you've got induction.

For example, the 19" colour monitor on my Sparcstation here at work
doesn't induce hum into my Ericsson phone until it's about an inch from
the screen.

Paranoia about the magnetic fields' biological effects is left as an
exercise for the reader.

That's good.  And the impedance mismatch is no big deal. I've just put up
another scanner antenna using the 3/4" hardline CATV coax.  I built my
own connectors out of 1/2" pipe-to-1/2" copper tubing fittings that
screw right onto the aluminum coax shield.  I cut a female-to-female
N connector in half and soldered the center pin right onto the coax center
lead.  I sweat soldered the N connector housing to the copper tube fitting
and screwed it onto the coax using NoAlOx on the threads.
I had an Austin Metropolitan tri-band mobile antenna that did not survive
mobile use.  This antenna is 3 concentric brass tubes like you buy at
the hobby store.  The widest and shortest is 1/4 wave length on 440, the
next is 1/4 on 220, and the wire up the middle is 1/4 wave on 2 meters.
I soldered it back together where it broke off at the bottom and mounted
it directly on the end of the hardline by soldering a Larsen NMO brass
base threaded ring onto the 1/2X1/2 copper tube fitting.  I had brazed
radials onto this fitting with different lengths for the different bands.
They sloped down at a more extreme angle than the usual 45' to attempt
a better match to 75 ohms.  I then coated the whole antenna with liquid
electrical tape.  This is neat stuff but expensive.  Available at your
hardware store.
It works great mounted 60 feet up a nearby tree.  The previous antenna
was a FAA discone with ethernet cable.  This antenna works much better
on all ham and scanner bands.

I just recently put up a Grove scanner antenna for my PRO-2006.  For coax
I used about 75ft of CATV drop cable the exact type of which is unknown.
I think it might be some type of RG-6, maybe RG-6U.  This coax has both an
solid shield around the foam insulator and braided shielding on top of that.
What is this stuff I have?  Am I loosing a lot of signal due to impedance
mismatch (75 ohm coax vs 50 ohm scanner)?

The quality of received signals has increased greatly so I'm not complaining.
I just want to know if I am getting the most milage out of my $40 antenna.

Yes, I've done it.  Sure enough I got another dB or so, according to
a Bird wattmeter.

The loss is almost totally due to impedance mismatch.  If you adjust
the antenna length to offset the reactance of the connector, the loss
should be negligible.

Something like the model of the ACM or the IEEE, where the basic membership
gets a "core" magazine or two (though see comp.org.acm for current flaming
on the quality of Communications of the ACM), and you optionally subscribe to
different special interest groups.  The disadvantage of that, however, is that
it fails to encourage people to broaden their interests; with QST as it is,
there's always the possibility that a technical ham will see a TV news report
about an airplane crash and wonder if he or she would just stand around
watching one uselessly, and might dimly remember a recent QST article about
public service; or a public-service type might one day look at his or her
radio and think "Gee, at least I know how to change the oil in my car, but
I don't even know what kind of oil my HT uses!  Gee, wasn't there an article
about electronics in QST a couple of years ago...?"

I wonder how thin the "core" QST could get and still devote enough space to
various factions to keep everyone reminded that there's more to ham radio than
their own peculiar fascination?  And, of course, how do you convince those
who just *aren't* going to realize that to read QST anyway?

I wouldn't expect to hear RS-10's downlink with a whip inside my

If you've got a steady signal on 29.357, it's not RS-10--probably
a 'birdie' in your receiver.  I've got one at 29.412 (in the RS-12
passband).  The beacon sends "RS-10" and a bunch of status stuff
on CW that you can monitor if you really want to know what mode
the bird is in, if it's healthy, etc.

   OK an OZ4 is a voltage regulator tube.  It works much like a zener diode
   does today only at higher voltages.  I will sink current from a power

   has the brighter it glows.  Zeners are very dull.  They don't glow

At the local swap meet I recently bought a Radio Shack HX-100 10-meter 
rig.  The plan is to use it mobile and I am at the "get input as to 
what antenna works best" stage of installation.  I would appreciate any 
input about types (brands) of antennas folks have used with this rig.

Tnx,

Pete
