Huh?  If memory serves, I've never seen a television UHF dial that went
beyond 60 in the first place.  And I know for a fact that I've never
heard of a UHF station higher than 54 (the local UHF PBS affiliate).

Subject: 10/12/15/17/20 Meter Quad
Date: 29 Aug 92 18:10:16 GMT
Organization: IBM, Austin

I'm thinking about building a quad for 10-20 Meters that includes the new 
WARC bands, but I'm a little concerned that there may be some interaction 
between the different bands (e.g., the 10 and 12 meter loops will be only 
about 10 inches apart).

Has anyone out there built a quad like this, or know of one?  If so, does
it work?  I'm planning to feed each band separately, and I'm wondering if
the impedences or element lengths will be significantly affected. 

Thanks for any info...

Organization: University of Waterloo
Date: Wed, 2 Sep 1992 21:50:12 GMT

Assuming one would wish to use/stock just one type of connector around the
shack for general use (including VHF and above) BNC and N seem like reasonable
options. BNC are fast to connect and thin coax is nice, but is not as common
and not capable carrying high power levels (as with high SWR) at VHF and above.

My reason for loving "N" connectors:

  (1) Their clean electrical and physical design appeals to the engineer in me.
  (2) They are more weather resistant that PL/SO 239s
  (3) I was not alive/active in WWII so 239s hold no sentimental value for me.

Mike (N4PDY) said:

"Free space path loss L dB = 20 Log F + 20 Log D + 36 (approximately)
where F = frequency in MHz and D = distance in miles.  Received signal
strength S = Pt + Gt + Gr - L, where Pt is transmitted power in dBm, Gt
is transmitter antenna gain in dBi, Gr is receiver antenna gain in dBi,
and L is path loss as computed above in dB.  Substituting and  solving
for D with S set equal to a minimum usable signal of, say, -110 dBm,
gives a best case range of 3,548 miles.  This is the range you could get
in free space.  Use of a gain antenna would vastly increase this range."

What is the theory behind the 36 dB loss constant term in the first
line?  I can see that power from a 0 dBi antenna would spread uniformly
over a 4 * pi * D^2 spherical surface, and I guess that the equivalent
capture area of a 0 dBi receiving antenna is something times
wavelength^2, but I haven't a clue on the dimensionless constants.

Second, why did you pick -110 dBm as the minimum usable signal?  If he
has a 3 kHz bandwidth, the thermal noise floor at 290 kelvins should be
about -139 dBm  (k * T * B).  Assuming 6 dB noise factor in the
(receiver + interference), that leaves a SNR of  23 dB.  Does that
correspond to minimum usable?

Thanks in advance for your help,

P.S. Any easily available references would be appreciated.

P.P.S. The 3 kHz I used assumed SSB.  He may want FM instead - how would
that change things?

Subject: Tuning open-wire fed dipole
Keywords: tuner, open wire, impedance
Organization: AT&T
Date: Tue, 25 Aug 1992 20:44:36 GMT

I have a 130 foot long dipole, center fed with about 80 feet (very
approximately) of this common brown insulated "open wire" feedline.
I use it on 80 and 40 meters and my problem has to do with the tuner
and the way the antenna tunes.
The configuration of the tuner is very conventional (homebrew).
The transmitter feeds the tuner with a link coupled with a variable 
capacitor in series.  The tuned circuit is balanced miniductor-style 
coil with a single variable capacitor across it.  The feedline is tapped 
onto the coil using clip leads an equal number of turns from the ends
of the coil.  On 40 meters it tunes and works beautifully.  I get good
bandwidth, both caps dip the swr smoothly, and the signal gets out
like Gangbusters.

On 80 meters, the only thing I change is the taps on the coil from the
feedline.  At the high end of the band, all works well, but as I QSY
down into the 3700 range I get screwy results.  The dips in the swr are
not sharp, the position of the taps has little effect, and when I go
down to 3600 or below it will not tune at all.  

It does not seem to me that the problem is wrong components.  I think
the problem is that the feedline may be presenting a low impedance
and the tuner likes a high Z.  

Two questions:
1). COuld someone please post the equation that defines the Z at the
end of a transmission line of x wavelength long, given the Z of the
antenna (about 50 ohms) and the Z of the feedline (about 450 ohms).
I can't seem to find it in the antenna handbook.  The only way they 
discuss the situation is to use a Smith chart and I'd rather use a
spreadsheet.

2).  On the assumption that I need to reconfigure the tuner as a
low Z tuner heres what I am considering.  Coax from the TX through a 
series cap to a tap on a parrallel tuned circuit.  Antenna (balanced 
feedline) to a link coupled to the parallel tuned curcuit.

Has anyone tried this?

Wayne-

I started to feel like an old timer when, at about age 35, the young ladies
at Wendy's wanted to give me the senior discount!

I also remember the 0Z4 tubes as metal, so you couldn't see any glow.  I
wasn't aware that they had any kind of gas, but that helps explain how they
get started.  As it was explained to me, the common electrode was bombarded
by positive ions causing it to get hot.  As a result of its temperature,
there was a cloud of electrons surrounding it, which were attracted to each
of the other two electrodes on alternate cycles.

Did someone want a 0Z4, or did they just ask how they worked?  I don't
think I have any, but I could check my stock.

        Not being involved in law, I have lost my way and need some

rule/law/regulation that can be used to over turn a Home Owners' Association's
ban on antennas.
        I live in a town house and according to the Home Owners' Association,
we (the tenants) are not allowed to erect an antenna.  As I have just passed
the exams for my license (amateur radio) and have become involved with the
local RACES (emergency communications in disasters) group I need an out side
antenna.

        If some one could point me in the right direction for what/where to

amateur radio operator to erect an antenna to be used in emergency
communications, I would greatly appreciate it.

Ham radio to link stations in a BBS network.  In other words,
what is the best (taking in account the availability/reliability,

an international network like Franco-Media which include French-speaking
BBS in Europe, North America and some remote places like Australia).
Choice would be : Amateur radio, commercial network like Phone, Data Pack
or other Data lines, Compuserve, link via local Internet, etc.
I know it is more easy to get today a license without having to learn

But, would it be cheapest to use long distance calls or to buy/rent
radio equipment.

Seems to me that we have a problem! This months RADCOM has a diatribe
against HF-packet written by some Antipodean type.

I accept that HF packet as currently practised is *not* good, but i dont think
AMTOR is an answer. AMTOR is a byte-oriented protocol; therefore it
limits the nature of what can be sent. Normal AMTOR has uppercase letters,
figures, minimal punctuation. Thats it. Even worse than conventional RTTY!

What is needed is a protocol that is not byte-oriented, so we can use it to
ship binary files, and non-ASCII text; then it could handle cyrillic, Kanji
etc. with few problems, as well as fax.

The method of encoding; PSK is not good (for all the reasons already
discussed). Something like Piccolo is far better; this was *designed* to
be used on noisy HF paths with the S/N ratio being unity or less! Problem is,
the installed user-base of TNCs. Not a lot can be done about this, unless
everyone runs out and buys Racal LA1117 Piccolo-modems.

perhaps its time for a change in bandplans too; surely manually generated
CW is just as much a 'digital' mode as packet, RTTY, Amtor etc?
A packet station on 28.245MHz would help get some of the intruders to give
up & go back whence they came.....

      I have an Optoelectronics model 2810, and I'm not happy with it.
It tends to double-count at low frequencies (20MHz) if the waveform
isn't pure.  It behaves as if the input is being differentiated; any
ringing causes double-counting.  When the zero-crossing point is clean
but the peaks are messy, the unit will double-count.  Clean sine waves
count properly.  Square waves with 1% overshoot don't.  You need to
examine the waveform being counted with a scope before believing the
frequency count.  

      There's no signal strength indicator, so it's hard to tell if
you're overloading the input or are down near the noise threshold.
Higher-priced Optoelectronics units do have a signal strength indicator.

      The power plug tends to fall out.

      $199 is too much; I paid only $129 for mine, purchased directly
from Optoelectronics.  But I didn't buy any accessories, like antennas,
cases, or stands.

      It's a nice little package.  There's also a bench instrument form,
which, unfortunately, is substantially more expensive.
