The add-on 12/17 kit did not affect the lower bands, but did affect
tuning on 15 and 10. Then when I moved I ended up completely
retuning -- changes in 40m tuning really affected all higher bands.
I'll agree with you that the Butternut HF6V is a great antenna. I run
it with the feedpoint 7' up and elevated radials.

I've seen folk curse at N connectors on 9913. It appears to me that the
9913 doesn't provide very good support for the compression gland in N
connectors, since the line is essentially hollow and made from (soft)
polyethelene. The N connectors I've seen sold for it are what I'd
call "short-barrel." You can get longer barrel ones that offer better
support for the line, and I find they stay on much more securely. You
have to do the center pin mod yourself to get them to accept the
larger center conductor of the 9913. (Sorry, I don't have the UG numbers
in front of me...)

One of the major advantages of amateur radio is that it provides an
activity that you can do while naked, and nobody particularly cares
about it unless you tell them. (Likewise you can smoke without annoying
anyone, etc.)
Please wear pants and shirt while soldering, though. Ouch.

Subject: Power Supply Questions
To: info-hams@ucsd.edu
I am in the process of designing a dedicated power supply for a
homebrew HF amplifier. The power supply will be used for nothing
but the amplifier. The problem is, I can't seem to find any
specifications in amateur publications for power supply parameters.
So, I have the following questions:
1) What ripple requirement should I try to meet for a
13.8V power supply? Is 10mV too stringent or not
stringent enough?
2) What kind of dynamic load regulation should I shoot
for? I currently have a design that will operate at
15.5 volts with no load and 13.8 volts with full
load. Is this good enough? What potential problems
are they with such poor load regulation?
Thanks in advance!

Almost anyting will disolve styrofoam except water and alcohol. Paint
thinner, gasoline, kerosene, MEK, acetone. I would try paint thinner and
if that didn't suit me I'd use gasoline second it is not much more flamable
than the rest and it is quick drying.

I'd like to point out that this goes counter to the way spark transmitters
work--that is the ones folk actually used for communications. There was
a good article a month or two ago in "Wireless World", part of a continuing
series on radio history, on the age of spark transmission. The spark
should be thought of as a switch, which simply connected the circuit in
a way that let it resonate and feed that resonant energy to an
antenna. While the tank was ringing down, the plasma of the spark
offered a very low impedance path for the tank current. At RF, the
plasma is continuous and offers a very low dynamic impedance to current
flowing in it. Maybe someone will actually build the suggested
circuit and check it out with a spectrum analyzer; it should be
trivial to short the spark gap (while the power is switched off,
of course ;-) and retest to see if there is any significant change in
the spectrum. Scott?? ;-) ;-)

Subject: Verticals
To: info-hams@ucsd.edu
Having used vertical dipoles and (slopers) for some years I can attest
to their good but not always excellent DX performance. The problem with
many of the antenna theory texts and amateur radio antenna cook books
is that they are in reality painting a much rosier picture than most
amateurs can acheive in practice. This is largely due to ground losses at
low radiation angles from capacitive (lossy ground) efects and poor ground
conductivity. Yes, a vertical dipole will radiate all the RF, but the ground
will dissipate much of the very low angle radiation, thusly masking what
would in theory be an excellent DX antenna in a very minimum or realestate.
I have found the 160 meter GAP vertical to be a big disappointment on
160. Apparently a much better counterpoise is needed than the four sixty
foot wires GAP suggets.
On 80 meters it does a good job... can work the VKs on most mornings.
On 40 it does a good job in the early afternoon. I used to be able to
hear Europe on my sloping dipole as early as 1430 local time, but could
never be heard, even with 500 watts. With the GAP they usually respond
with at least as good an RST as I can give them.
On 20 the GAP seems a bit dead unless the band is very good.
I don't know why this should be. I would presume since its physical
length is over the 1/2 wave dipole requirement that it would work as
well as a vertical dipole, but again theory and practice seem at variance.
Has anyone else used the GAP (45 footer on 160-- 20 meters).
I would presume from my experience that its efficency varies widely
across its design frequency range.

I owned and used one for a year or so. Worthless on 160, deaf on 80,
good on 40, mediocre to bad on 20. None surprising. It is a 1/2 wave
center fed on 40, 1/4 wave with a compromized radial on 80, 1/8 wave
with alsmost non-existent radials on 160, non-phased full wave on 40.

Ham radio is a big hobby with many different parts, interests and
sub groups. Any hobby that involves wireless communication
would qualify for it. This implies a number of things:
- The sheer number of activities will reduce the percentage of
participation for any one activity. It is like having a field
of hundreds of candidates running for president. If there
are more than a few credible ones then the percentages are going
to be small regardless of the numerical size of the following.
Further,
- I do not think that any one ham can reasonably claim to
represent all interests
- I do not think that even one organization can, for that matter
So it is not surprising that any one organization does not have all
the active hams, much less all people with call signs allocated by FCC.
But, I think that ARRL does really try to respresent the parts that
I am interested in. When I feel that does not, as I did when the
digital committee in its infinite wisdom requested 1.810 to 1.830
for automatic unattended packet, I write to my director. I wrote a
letter and had thirty or so hams co-sign it and sent it to W9prn. Followed
it up with phone calls and visits to make sure that he got the message.

I can perhaps see your reasoning: customer is right, arrl is an
organization of/by hams and staffers work for ARRL and so on.
But when you assert that your statements must be accepted by all at
ARRL, you make an error in your syllogism. They do not work for you
(you in singular here). They work for all members and have to represent
their intestests as a *whole*. This may involve disagreeing with an
individual member now and again.
