I posted a similar request on GEnie the other day and got a very nice 
reply from someone who said "It's just a regular vertical, with radials 
buried at night, underground, and a cone at the base to cover any 
matching coils, etc."  I don't think the idea would work with my 
Cushcraft R7 because of all the doodads and stuff hanging out of it, but 
something like a Hustler or Hy-Gain vertical might just do the trick.  I 
would use some type of PVC tubing more than likely.  Good luck, 73,

Sorry, I was a little ambiguous with my last posting.

The BC-14 puts out only 75mA.

The car adapter should easily put out 2A.

If you use a hefty home power supply, the batteries will charge while you use
the radio.

If you don't have the battery in, that is fine as long as the power supply can
push enough current.

PL, actually CTCSS, tones aren't assigned by the FCC. They are chosen
by the user in conjunction with the frequency coordinator and other
users of the channel to avoid conflicts on that channel in that area.
Not all users use CTCSS, some run open, and some use other selective 
squelch methods. It's mainly a matter of convienence for the user.

No, the second one will drain 2x's as fast due to priming the karma pipe line.
Now you'll need a piece of wood  4x's as thick to isolate the battery.

  Yes, that IS the case.  Only TYPE accepted (for CB service) equipment can

Indeed, it's sobering to realize that a monster antenna may only
be worth 1/2 an S unit. Seems hardly worth the bother. It *is*
often worth the bother, but only because of the 6 S unit front
to back ratio of the monster beam that allows notching out interfering
stations. That's usually much more important than the forward gain
of the antenna. Most of us rarely operate within a 1/2 S unit of 
the noise floor at HF.

I've been told several reasons not to set lead acid batteries on 
concrete, including that it would discharge.  (Never found a good reason 
_why_ it would, tho...)  Two other reasons that come to mind:

1.  Acid from the battery (solid/liquid on the case, or gas vented) will 
eat away at the concrete.

2.  In a semiheated storage space (attached garage, etc.), if the battery 
is sitting on a concrete floor next to an outside wall, the concrete can 
act as a heat sink and possibly freeze a battery that wouldn't freeze 
when sitting on a thermal insulator (piece of wood).

Subject: Help With 432Mhz Yagi
Date: 11 Sep 92 05:21:47 GMT
Organization: kd4dts

Time to call for help.  I want to build a 432mhz Yagi.  There are two
designs in the ARRL Antenna Handbook, both of which have good points
and bad points.

The first antenna is the NBS 3.2w 15 element antenna.  This one is
real nice because the boom is under 8", which is a common size of
1" aluminum box section.  However, I can't figure out how one is
supposed to feed this thing.  There is no discussion I can find on
how this might be done.

The second antenna is a 15 element Yagi, with a boom length of 117"
(9.75 feet).  I understand how to feed this, but don't know what the
implications of either shortening the inter-director length is, or
just eliminating two of the directors would do.  I know it would obviously
affect the gain and F/B ratio, but by how much?

Can I use the feed technique from the second antenna to feed the first?
Also, in the feed technique for the second, they mention using "Steatite"
standoffs.  I'm not an antenna expert, but I would assume that these
are insulated, seeing as the feed line is attached to these standoffs,
and the otherside of the standoff would be ground.

If you have the Handbook, the first antenna is on page 18-10,11 and the
second on pages 18-26 and 27.

Any help that can be given would be seriously appreciated.

Auto mechanics come up with the darndest explanations for the things they have
always done!  The reason that they come up with this folklore is that no one
that actually understands the real reasons for these actions bothers to explain
them to the mechanic (or maybe the mechanics are just plain stupid?).

The real reason (according to Chuck that is) for putting a piece of wood
under a lead acid battery is to prevent any spilled acid that is on the
battery case from corroding the floor.  Concrete is an alkali substance,
and batteries contain sulfuric acid.  Battery acid will really tear into a
concrete floor; but, it has little effect on wood. (wood was once used
inside of car batteries as separators and supports.)

I purchased a Kenwood TS-850S with built in antenna tuner a little
over a year ago and I love it. The receiver is great and I get nothing
but good comments on the sound of the audio on transmit. Although
like most all of the radios on the market today it has some bells and
whistles that I'll never use. But it also has a lot of features that
I didn't think I'd care about at the time I bought it that I wouldn't
do without now. As far as service goes...the mic that came with the
radio didn't work right from day one (problem with the switch...it would
not pop back out when you let your finger off it...no big deal but it
wasn't right) so I called the service number that HRO gave me. A very
nice person took my phone number and said that someone would call me back
when they got time. Within 10 minutes (ok maybe 15) a person called me
back...I told them the problem...they said no problem...3 days later I
had a new mic in my hands that worked perfectly along with a note saying
I could just keep the other mic. Now granted this wasn't a big problem
but I don't know what they could have done to do a better job taking
care of the problem. I was happy...and have not had one other problem
with the 850.

I keep thinking that what the market needs is a HF rig for $400. I don't
need all the bell and whistles that the overpriced HF rigs have. I am
using a old Swan 700CX with excellent results. What I would like to see
is a basic rig with 2 VFO's, a couple of memories and over 100 watts output. 
Also with a built in power supply. There is a real hole in the market waiting 
to be filled by a rig like this.

   The crop of all-mode 10m radios are essentially no-frills radios with
only one band. If you add in $125 for the cost of band switching relays
and low pass filters (inductors and capacitors), then you end up still
below $400.

>I don't think an all-band HF rig with

Keep in mind most of the multi-VFO radios sold today have only one PLL
synthesized VFO and emulate multiple VFOs by reprogramming the PLL
synthesizer. There is little difference between an additional VFO and
a memory channel.

Yup, and my TS-520S sold for $600 new, too. In the low volume amateur
market, I think the prices tend towards the highest the market will bear.
In high volume markets, like CB, the prices are seriously eroded.

Let me answer once to all of those who have wondered where the AMSAT
material has been the past couple of days: The amsat.org host in San
Diego suffered a massive case of catatonia on Tuesday. I haven't got
details, but Brian, WB6CYT reported that he couldn't even get it to
boot.

The host we had been using for amsat.org was an antique SUN 2/220
that Brian had built out of hios junk box. We had intended to replace
it with a more modern host and had selected a SUN 3/60.

We had placed the order with a firm in the San Francisco area who had
brand new 3/60's at a very attractive price. The hardware was supposed
to be shipped from the Bay Area direct to Paul, KB5MU in San Diego.
Alas, on Wednesday it was delivered to the AMSAT office in Maryland.
The vendor had screwed up. Martha and Paul embarked on heroic efforts
to get the hardware from the Atlantic to the Pacific coast.

Today Paul got the engine to Brian, and amsat.org is again QRV, now
running the new CPU. 

For those of you who sent messages asking why they weren't receiving
messages, or why something had bounced, now you understand. It may
take a day or two for the problems to get sorted out.

I just resent N3FKV's two-line elements for this weekend. They were
caught in a problem when they were sent the first time.
