Subject: 10m contest 3/16?????
To: [e-mail]

oIn my official "1991 Ham Photo Calendar with Contest and DX Reference",
there is a contest listed for March 16th as:

    "County 10 PH 1200Z (36)"

Which I would translate as some kind of 10 meter county hunters phone contest
starting at 1200Z and lasting 36 hours.  However, I cannot find a reference
to this contest in any of the major ham radio magazines (QST, CQ, 73, Radio
Scan).  Before I run out to Delaware this weekend, does anyone know if this
contest is really happening?

Subject: About Other "CB" Bands
To: [e-mail]

A few people have been asking about the 462 - 467 MHZ "CB" band and this may
clear somethings up.

This frequency band is better known as the GMRS (General Mobile Radio Service).

Who can get a license: Any individual can get a license.

How : Just fill out the FCC form 574 and send it in with $30
      The form is somewhat of a pain to fill out (i.e. very specific).

The frequencies are given out in pairs so that a repeater can be used.
The maximum power output is 50 watts and you are technically allowed only
one frequency pair.

It's not practical for a full-power HF transceiver.  20 Amps at 12 volts
is 1/3 horsepower, even assuming 100% generator efficiency, which is
a bit more than the average out-of-shape ham can manage!

I have heard of people just using a standard bicycle light generator
into a voltage doubler/filter/3-terminal regulator to power an HT.
You only have to make 5 contacts to qualify, I believe.

Subject: Ham interference on Cable TV?
To: [e-mail]

A question for those wiser than I....

My friend's cable tv gets interrupted several times a week by
what I think are ham operators.  I can get parts of a callsign
at times, but have yet to understand anything clearly enough
to be sure of the call.  Repeated calls to the local CATV company
have not solved their problems.  If we are able to hear a clear
call, what should we do?  I know I can look up the operator's
name and address, but what then?  Send the ham police?  Call up
and leave nasty messages?  Leave nice messages?

I am not a ham user, but I have a friend (out of town) who has
explained some of what I described above.  Any suggestions?

Thanks,  Matt Byer     [e-mail]

What kind of experiences have you had with Hamtronics kits?
What about "wired & tested" stuff?

I'm mainly interested in their UHF receiver.

Any information would be apprecieated.

I picked up a piece of surplus microwave gear last week, it has WG 16

It has 3 ports (with a 500W dummy load on one of them!) and it bears
the following markings:

Micromega Div. Bunker Ramo

Mod - 32904
Ser - 2527

Any additional information/specs would be welcome.

To: [e-mail]

My father is going to (finally) upgrade to General.  I understand how
the new volunteer examiner system works but I'm not sure how the code
tests are actually structured these days.  The last time I took a code
test I got to sit in front of the FCC and sweat a lot.

What sort of a test should he expect?  How is it graded?  Is a sending
test still required?  Are there any hints for taking the test?

I believe there was a thread on this a few months ago.  I'd appreciate
it if someone could summarize the comments for me.

Thanks

My wife and I bought a pair of these and sseveral people in our repeater
club have them; no problems.  I'm just a little squeamish about doing the

the general test? Seems like I could and should just develop my ear at
13 wpm, know I could pass the written test easily. Does anyone have

duplicate effort. Please e-mail your advice. Thanks!

  From having operated just such an antenna for many years, I can claim
that this is definitely NOT true.  The bandwidth is just fine.  Since
the resistance of the wire lowers the Q, it may even be a bit broader
than one made of heavy wire, but I was unable to measure that difference.
Mine covered 40 meters just fine.
