Subject: "outdoor antenna" ban
To: [e-mail]

Anyone have any good ideas on how I can fight a complaint
about my "outdoor antenna"?  It's a 2 meter ground plane
that I take in and put out (it's mounted on a wooden stick).
for a couple of hours each evening, and on weekends.

I live in an apartment co-op that doesn't allow antennas.

Well, its just a temporary antenna at that, and no worse
than someone hanging a power cord out their window to
vacuum their car!

Any hints and tips?

Much obliged...

Well, here's what Webster's Ninth New Collegiate Dicrionary has to say:

baud \'bo d, 'bo d\ n,  pl baud also bauds
[baud (telegraphic transmission speed unit), fr. J. M. E. Baudot  1903 Fr.
inventor]
(1931)
:a variable unit of data transmission speed sometimes equal to one bit per
second

It indicates that bauds is an acceptable plural. Then again, their definition
seems a little flakey. Oh well...

Subject: characteristic impedance
To: [e-mail]

You might also consider measuring the dimensions of
the cable.  This is pretty easy to do, even at a hamfest.
My favorite tool for doing the measurement is a dial
caliper, but comparing the unknown cable against
known cables is probably good enough for most purposes.

Basically, there are two factors that determine the
impedance.

1. The ratio of inside diameter of the shield to the
outside diameter of the center conductor.

2. The type of dielectric (the stuff preventing the cable
from shorting out).  You want to compare cables
of similar dielectric.

Exposing a few inches of shield/center conductor is a
good idea--sometimes the cable is damaged by water.

Hello All,

 I was wondering if anyone knows of a GOOD receiver for
the subject mentioned services over radio.  I was thinking about
the Kantronics Kam, but have been hearing not so good stuff about
it.  Plus I only want to receive, so I would also be paying for
the transmit section of the device.  But if it was really good,
I probably would pay the money... Any help would be appreciated..


     Thanks.. Pete Geremia

Since KC7AA would indicate an advanced class (2x2) the most logical would be
the 2x3 for the novice/tech.  I don't know if the 1x3's for the tech are gone as
they are here in California.  All new novice, tech, and general class gets a 2x3
call.

... well the irritating thing is that many (most?) stores don't tell you
about the coupons in the back of the catalog.  It's on page 70 or between
70 and 71 ... tear out things.  I used my $3.00 discount coupon to purchase
the catalog while buying a null modem adapter.  Don't recall if the purchase
had to be $5 to get the discount.  I'm sure it had to be at least $3 to cover
the catalog. :-)

My brother called me from another store where they couldn't locate an item
in the catalog.  I told him the name of the product from my '93 catalog but
they didn't know what it was ... and they wouldn't give him a catalog.  He
called me to get get the page number and tried to get them to give him a
catalog if he gave them the page number.  He made his purchase but that
particular store certainly didn't earn any points that day!  Wish I had
known about the coupon in the '94 catalog before he called me.

Their "upfront" charge for the catalog is bound to make a lot of folks mad
... more of their managers should point out the discount coupons.  I see
the $2.95 on the top right corner ... don't look and further to the note
describing the discount coupont offer.  Didn't work for SEARS either.

Here's a neat feature of the new Motorola Visar handheld, that I hope will
show up on some future hamband talkies. The Visar is a tiny 5-watt
16-channel handheld, designed for police and similar applications. It is
available in VHF, UHF and 800-MHz-trunked models. Cost is $1,095 each. (At
least that is what I recall the salesman saying.)

The Visar has an LCD channel display mounted on top at a 45-degree angle,
so it is visible from above (if the radio is in your shirt pocket) or from
the front (if you have it in your hand). Of course, that means that the
display must be upside down from one or the other position.

The neat feature is an invert button. Press it and the characters in the
display electronically invert! No need to read upside-down numbers!

Hooray for Yankee ingenuity!

Subject: Please Help QSO
To: [e-mail]

Greetings!  I need a little help.  I've, finally, got my shack up.
I'm running an HW-101 with an MFJ 941-D tuner into a 20m dipole.  Now..
being a tech+, I can't use 20m, and I'm not generally around during the
day to work 15 or 10; so I'm trying to work 80 or 40.  I can't get the
antenna to adequately tune on 40, but I get good results on 80m (low
SWR, 100w forward, 1-5 w reflected max).  Problem is I can't seem to get
a qso...I don't know if I'm not being heard (although I took a receiver
over to a friends and he could here the signal WELL) or if people are just
avoiding my straight key SLOW code (but I need to QSO to build my speed, so
could you fine people out there please listen for N9UXU on 80 meters
(around 3700 depending on static peaks) for the next few evenings at
0300 UTC (november 5-8 UTC)?  I'd really appreciate it.  Also, if you
hear me, but I don't respond, email me. The rig doesn't have RIT (yet), but
I "listen around", so I don't think it's the problem, but you never know.

Thank you!

Subject : Re: Was 'Vanity' Call Signs, now paying for call signs

Don't we pay enough taxes to the gov't?  I object to paying additional for
anything that we now have.  I remember paying $20 for a citizens license (I
fly RC model planes and used to have to pay $20 for a 5 yr license).  It
was really neat when that fee was abolished, but it wasn't done at the
gov'ts initiation, someone brought suit (or somehow stirred the pot) for
that abolition.  The crux of the matter is:  I don't want to pay!!

When the gov't says they are not raising taxes, I shudder.  I have watched
my tax bill rise a great deal over the last 10 years with exemptions
disappearing and Social Security ceilings (as well as percentages) climbing
faster than superman.  I would rather buy more radio equipment than support
much of the waste in Federal government.  Anything paid to the gov't I
consider as a tax (except perhaps copying fees when I order documents).

Sorry to vent my feelings on taxes in this thread.  Just wanted to go on
record that I don't want to pay for callsigns because it comes out of an
already stretched pocket!

A few notes on 10 meters:


1) Propagation on 10 meters is usually either great or terrible.  You are
either working the world with 10 watts SSB or not working anywhere.
There are a few exceptions, but generally, it's either hot or cold.

2) The level of sunspot activity is very important.  The last maximum
was in 1989, with excellent conditions lasting for over 2 years.
We are now heading to a minimum in the 11-year cycle.  (11 years is
an average; the current cycle was much shorter)
The next maximum will be around the end of the decade.

3) In most of the U.S., 10m tends to be dead during the summer, even during
sunspot maximums.  It starts picking up in the fall.  November/December
tend to be good months.   Spring can be good too.

4) 10m can be downright dead during sunspot minimums.  With the solar
flux hovering below 100 like it is now, you can expect to find
limited activity.  A couple of years ago, when the flux is over
200, things were great.  As expected, some of the 10m-only rigs
like the Radio Shack HTX-100 bought back then can be had for
a big discount now.

5) Sporadic E propagation occurs most frequently around the two
solstices (December and June).  Contacts made with Es are generally
between 400 and 1000 miles, and are subject to rapid fading.
You may want to turn on your 10m rig around Christmas time
to get in on some of this activity.

6) The guys with high antennas and power can sometimes still get
through when conditions are not great.

That's true, but the numbers you quote don't really tell why the
HTX202 is so much better than the wideband scanners, er HTs, sold
by others. The RS intercept is higher, but the data posted is for
in-band signals. Where the RS unit really shines is when you realize
that out-of-band signals are attenuated an additional 30-50 db by
the narrow front end filters which will place out-of-band mixing
products 60-100 db further down than in-band mixes. The adjacent
channel performance is basically a measure of the IF filtering.
There too the RS unit shines.

This is a very good radio for areas with high strength commercial
signals. That's nearly everywhere near a large city today.
