Subject: Azden HTs
To: [e-mail]

I am a new ham (expecting my ticket in 2 weeks - I passed the Tech on 4/12!)
looking for a 2-meter HT which doesn't feel like a toy.  Guess I've been
spoiled with using Motorola HTs for so many years...  I saw a brochure for
the Azden units, which meet MILSTD 810 for ruggedness and appear to be roughly
equivalent to an HT600 or MT1000 in size.

Anyone have any experience with Azden gear which they could share?

Many thanks.

Go back to Radio Shack (or your local ham store) and get a copy of "Now
You're Talking!" from the ARRL.  It has tons of information in it that
you need to know, as well as the question pool.

Some tests are 10 fill-in-the-blank questions, but all the VE sessions
I've seen and participated in check the answers to the questions
first, and then check for solid copy if you fail on the questions.

There are excellent computer programs around.  If you're using an IBM

favorite).  I know there are ones for the Macs, but have no personal

Check at a local ham shop or Radio Shack -- they can probably give you
contact information for a local ham club, who either gives the tests
or can point you to someone who does.  Also, the ARRL posts a mountly
list of exams around the country (that they know about), that you can
FTP from their server.  The info on getting stuff from their server is
usually posted here at least once a month, if not more often.

Good luck!

                      BIG BOATANCHOR BASH!!!
                 CENTRAL GEORGIA NATIONAL HAMFEST
                          PERRY, GEORGIA
                          August 6, 1994
                            0800-1500


    Now is the time to begin planning to attend the Central
Georgia National Hamfest at Perry, GA, on August 6, 1994.  The
hamfest will be held at the Georgia National Fairgrounds, right
off I-75, exit 42.

    Activities include:

    **   The Boatanchor Forum, conducted by Jim Kearman, KR1S.  As far
as I know this is the first hamfest forum devoted to boatanchors.  It
took a little talking to get the hamfest committee to put up the money
for Jim's trip.  Come on down and help me convince them that they made
a good investment.

    **   A Repeater Forum. (Repeaters are very useful to discuss
boatanchors.)

    **   How to become a Ham Forum. (Boatanchors are much more fun, if
you are a ham!)

VEC testing will be conducted.  Walkins accepted. (Upgrade now so
that you can put a boatanchor on every band!)

Dealer spaces are available inside.  If you insist on having suche
amenities as a table, chair, and air conditioning then this is the
place for you.

A large Bone Yard space, right outside the main building, is available
for FREE!  That's where you will find me along with a pickup truck
full of stuff. (Don't have to carry those heavy radios quite so far!)
Bring all of your excess boatanchors and let's see how many can find
new homes!

Refreshments available at the hamfest. (What's a hamfest without
hot dogs?)

Lodging is available in the immediate vicinity of the hamfest.

    Talk in:  146.25/85

Subject: Gray Areas of 'No Commercial Use'
To: [e-mail]

Question: I'm going for my Tech license on Aug. 1st and I've been thinking of
some neat uses for packet radio.

I was thinking of using a laptop + TNC + HT and a PC + TNC + another HT at
home and using the laptop to connect to the home PC with packet <said home
PC runs UNIX so such things are readily possible>.

One of the niftier uses for such a setup would be able to do things like work
on projects from *ANYWHERE* within the range of the two HT's running alone with
no help.

But then I was thinking, would, for instance, using such a connection to work
on some shell scripts I was writing for my job be considered 'Commercial Use'
?

What if I told my PC to dial up my Internet access provider and checked my
mail? I've paid them for a service, so is my dialing up their terminal server
and logging in a commercial transaction?

Just curious.

>There is somebody that can solve my problem ???

Yes, it's possible. We need a bit more information to be of help. First,
what TV channel suffers interference? Is it just one channel or all?
What frequency are you transmitting on when it happens? One in particular,
or all? What does the interference look or sound like on the TV? What kind
of antenna is being used on the TV? Is the normal signal on the TV weak or
strong?

As I recall, your TV system is all UHF (correct me if I'm wrong). So it's
possible that a harmonic of the 2 meter range of the HT is getting into
the TV. Or it may be that the TV is suffering fundamental overload from
transmissions on the UHF part of your HT. The latter is unlikely unless
the TV signal is weak at your neighbor's set, and unless the antennas
are really close together. More likely, if you are transmitting UHF when
the interference happens, is that your HT has a spur. Low voltage from
the AC adaptor could cause this.

We really need to know what the interference looks like on the screen
of the TV. That will tell us a good bit about what kind of interference
we are dealing with.

There's no national system in the US, but in some States or localities
the presence of a ham tag may, or may not, ease your passage through
a roadblock set up to prevent sightseers and looters from entering a
disaster scene, depending on how the cop running the roadblock feels
about hams. In general though, it's just a vanity plate of a special
kind.

Ah, well, that says it all. :-)

It's true that even a wet string will radiate after a fashion. I've
even made fairly distant contacts using a lightbulb dummy load. And
we all know how good rubber duckies are, but we still use them. Still,
there is a large difference between a Ringo and a Comet. There's often
enough difference to make the difference between needing an amplifier
and not on transmit, and enough difference in receive to make or break
a contact. Whether that's important or not to you is an individual matter.
It just seems odd to me that people, who will spend *thousands* on radio
equipment, balk at spending a few extra dollars for a good antenna system.
A better antenna is almost always more cost effective than a better radio.

That's hard to come by. You can't really believe some of the manufacturer's
advertising claims, which is why QST stopped printing them, and most antenna
measuring contests are either not reproducible, or concentrate solely on the
gain of directional antennas. Therefore we have to depend on word of mouth
experiences, and on antenna theory, to tell us which omni antennas should work
best. It would be interesting and illuminating if the ARRL were to commission
a "shootout" between all the major antenna designs, conducted on an independent
antenna range. My informal testing and experience says lots of people would
be surprised at how their favorite antenna *really* performs.

On the other grasping member, the Ringos I've had have been prone to
rather rapid corrosion, and perform poorly when wet. (Actually they
*always* performed poorly compared to a good antenna (skewed patterns),
they just got worse when wet. I found that to be true of the Cushcraft
AOP package too, but their long boomers seem to work fine, probably
because of the different driven element design.)

Side note: the amateur satellites offer a wonderful real world signal
source for testing steerable directional antennas. They aren't so good
for testing typical terrestrial omni antennas though. That winds up to
be so installation and local terrain dependent as to be almost intractable.
Even careful antenna range measurements may not fully apply in your local
situation because your installation may not be similar to the range at
all. I've installed several different antennas at my repeater site and
then did coverage tests. So far, the best amateur antenna (electrically)
has been a Comet. It has also held up well mechanically in that severe
environment (970 feet AGL, high winds, thunderstorms, and a once in a
century ice storm didn't faze it).

Well the best set of plans is to buy a Comet and copy it. :-)
Number 12 solid bare house wire and some UV resistant PVC pipe
are all you need to duplicate one. There was an article in 73
Magazine on making a coaxial colinear that is functionally the
same. A local ham made one and found it to compare reasonably
well with the commercial antennas. Where home designs of this
type usually fail, however, is in the mechanical details. There
is usually at least one specially made part that is hard to duplicate
at home.
