    Would someone with a software program for calculating
antenna measurements be kind enough to give me the dimensions for
a yagi (wide spaced or optimum -- doesn't matter) of two or three
elements with a center frequency of 490 Mhz. I'd prefer the equivalent
of plumber's delight if this is available or at least a simple matching
device to avoid expensive coaxial baluns.

    Thanks for the help in advance.

Yes, I saw it.  Also, looking back, it was *your* comment in the first place
that said you could cancel the -40 from both sides.  The original d poster
didn't.  (He said the formula worked because the scales corr
corresponded at -40.)  Everyone who jumped on you said of course you could
you couldn't just cancel them.

Thus, the only idiot saying that you can cancel them is you!  Don't
try to brush it off on someone else--like you alwasy do whenever
you suddenly realize what you said earlier was wrong!!!!

I have had my R7 since they first came out (late '91?).  I run a KW into
it on all bands 40 thru 10 (well, except 30, where there IS a power
limitation) and I have never had a trap failure - not even heard of
anyone having a trap failure.  Also the SWR curves for my installation
match (or in some cases are better than) those published by Cushcraft.

Good Day all!

Ive lost the FTP site at which resides a very complete list of mods for
our rigs. Can anyone mail me that site address? Ive determined that the
742-942 kenwood rigs have filter and preamp modules for extended 450 coverage
and 800 coverage, and Id like to enable them.

Thanks Y'all

Subject: need IC-4AT for space flight
To: [e-mail]

The University of Maryland Radio Association, is trying to acquire one or
two ICOM IC-4AT UHF radio units to be used in a satellite data downlink
subsystem

We are aware that production of this model has been discontinued, but we
are interested in this particular model because it fits our requirements.

 It is important that the unit is in (relatively) good condition, has not
undergone extensive abuse and, especially, has not suffered a drop.

Please, if you have a IC-4AT UHF radio and you consider selling it or
donating it for space flight call:

That'd make an EXCELLENT April 1 article. I recommend writing it up. I bet you
could take in a major portion of the Ham community with it. <^_->

Let's imagine a strange beam. It has uniform gain over 36 degree angle and
receives nothing over the rest of the rotation.

In the absence of "cosmic background" noise is constant. It is relatively
unchanging over most of the rotation. Most urban or suburban noise levels
are also relatively insensitive to where the antenna is aiming. So that noise
exists with out regard to antenna directivity.

Two things WILL vary with aim, however. Powerline static and storm static
will vary depending on whether you are pointing at them or not. SO in this
case they'd be attenuated 10dB. Signals also will depend on whether you are
pointing to them or not. So your signal level drops 10dB. But the signal is
what you want to get. ANd your ability to DO something with the signal
depends on its power level. But the scanning antenna has simply reduced the
signal level by 10dB. SO your signal to noise ratio drops the same 10dB for
most forms of noise.

Worse yet assume the powerline static is positioned 10 degrees off from the
signal's location. WIth the postulated antenna you can slide the "cutoff"
on the beam pattern over until the static goes away with the signal present.
This is a VERY high signal to noise ratio situation if we "neglect" for the
moment the other background noise. But if we rotate the antenna we get equal
time on signal and noise so we are back into the low signal to noise ratio
domain a non-directional antenna would give us.


ALl that said, except for the powerline static postulated, the rotating
antenna is basically a "chopper" attenuator on the antenna lead which
switches you from a signal plus noise source to a noise only source. It gives
a distinct disadvantage in the signal to noise race.

I'm pretty sure it is illegal in the U.S.A., but I knew a couple of guys
who did it anyway before getting their Novice tickets -- it was pretty
clumsy the way they did it, transmit by keying the mike and down on AM, and
receive on SSB.

Just to make it clearer...

There are fees for examination via National Radio Examiners--W5YI...
those are paid to the Test Center Manager in whatever form is
acceptable locally.

Now that the FCC is charging licensing-associated fees, the FCC fees
are paid with check(s)/M.O.s made out to the FCC.

There two fees schedules (and payees) are seperate.

I believe that the monies received by the FCC are deposited into
the U.S. Gov't General Fund.

Then why was a communications emergency declared by the FCC for a

passing traffic on 80? NTS? RACES? ARES?

I've had a Ringo Ranger on top of a 60' tree for about 3 years.  It still
outperforms the Isopole on top of another tree.  I buy all the Ringos I
can get at swap meets.  For a definitive article on "Ring Gamma-Matched,

magazine.  If you can't get a Ringo to work for you then you deserve to
pay for a Diamond or Comet.
