I agree with Howard. I use a single, 65-foot long dipole on all bands from
80 through 10 meters using an open-wire feeder. It works like a champ
with little or no RF in the shack. The difference in transmission line
loss between open-wire line and coaxial cable is VERY impressive--
especially under high SWR conditions (which tend to occur when you
feed an antenna at nonresonant frequencies).
Open wire gets a bad rap as being difficult to work with. This is not
true in many circumstances.

Each side of a 20 meter dipole is a half wave on 10 meters this presents
somthing over 2000 ohms impeadence on 10 meters resulting in a about a
1:40 SWR. This will give you a great deal of loss in the coax if you
are able to match it. Also if you go to open line to get away from the
loss it is likely to put RF in the shack. The only way to fix this is
to shorten or lengthen the antenna to an odd number of quarter wave
length i.e. 1, 3, 5, 7 and so on.

New amateur radio society for the Russian Federation
====================================================
The disintegration of the USSR saw the collapse of the former
country's amateur radio society, the RSF. There is now a new
national amateur radio organisation registered in the Russian
Federation, known as (in English) the "union of radio amateurs
of Russia", otherwise called the SRR.
It was registered last April with the Russian Ministry of
Justice as the country's national amateur radio organisation.
The SRR is seeking membership of the International Amateur
Radio Union (IARU).
If you're going to the Russian Federation and are interested
in operating while you're there, you should apply to the SRR.
They have an agreement with the Telecommunications Author-
ities which enables them to provide this service.

WAE RTTY Contest rules part 2
====================== ======
Multipliers: each DXCC/WAE-country counts as a multiplier.
Multipliers count only once per band.
Multiplier bonus:
A multiplier on 3.5 MHz may be multiplied by four.
A multilpier on 7 MHz may be multiplied by three.
A multiplier on 14/21/10 MHz may be multiplied by two.
WAE Country list : C3-CT1-CU-DL-EA-EA6-EI-F-G-GD-GI-GJ-GM- GM

4J1-4U1(Geneva)-4U1(Vienna)-9H1.
QTC points: Count 1 point for each QTC reported to any station
NOT ON YOUR OWN CONTINENT. Each station may both send and
receive QTCs, but the sum of QTCs exchanged between two
stations (sent plus received) must not exceed 10. Eaxh QTC
(message) will contain: Time, Callsign, Number. Example: QTC:
1307/WA7EGA/131 means that you worked WA7EGQA at 1307 UTC and
received his serial number 131.
A QSO may be reported only once and not back to the
originating station. (You cannot report a QSO with WA7EGA back
to WA7EGA for credit). The same station may be worked several
times to complete the quota of 10, but only the original
contact has QSO point value.
A uniform list of QTCs sent must be kept. QTC 3/7 indicates
that this is the third series and that 7 QTCs are now being
sent. Record all received QTCs on a separate sheet with a
clear indication of the sender. If more than 100 QTCs are
claimed, a QTC check-list must show that the maximum quota of
10 QTCs per station has not been exceeded.
Final scores: Multiply total number of QSOs plus QTCs by total
number of multipliers

the callbook and CD rom folks both start at the same place - the FCC records.
i think the callbook folks were taking reports of changes in QTHs and revising
accordingly. the CD rom folks are going to take the FCC data and reproduce it
with a minimum of editing.
i think there are a fair number of SKs in the listings, but by far the biggest
errors seem to be people that move without notification to anyone else.
heck we even had a kid pass a novice test and his licensed grandpa comes back
something like 6 months later complaining how we lost his application. turned
out the kid and his folks moved the next week after the exams and didn't
forward the mail (this seems exceedingly dumb, but i suppose some reasons
probably exist for doing this). The FCC had sent the license to the address
given at the time at the exam.
a while back i compared the callbook data versus the internal employee lists
we've got here (everyone gets a roster... lists address, spouse name, phone
number...) and found about 20% of the ham folks were out of date on
addresses -- did let the folks involved know, and i think now everyone is up
to date (and I keep a small stock of 610s in the file in the radio shack
upstairs too).
these aren't no codes folks. these folks just didn't bother to notify the FCC
of the address change.
of course, the FCC wants everything on a 610 - that could be a stumbling block
since when you move you have to send out a bizillion post cards to everyone as
well.
if W2NSD wants to complain about addresses being out of sync at the FCC, maybe
he should run a column where he compares FCC data against his licensed
subscriber lists and print the results for all to see.
Maybe a "QTHs Lost and Found" column in 73. or a Lost QTH Server on the
internet or something....

Actually, that is the JDR catalog, and the kits are Ramsey's. Unfortunately,

I wonder if they work any better if you buy them from JDR rather than Ramsey?

You won't be sorry. I have over 20 car-years (2 cars, 10 years each) experience with
NMO mounts and am still happy with them. You can get little plastic plugs from Larsen
to fill the holes when you sell the car.

I have two Toyotas and on each, was able to remove the dome light and work through
the hole in the headliner. I used a Greenlee 3/4" punch, but I understand
the drill is also quite popular. Make sure you scrape the paint on the inside of
the roof. I did it by tightning the mount slightly and rotating it, using
the ground clamps to scrape away the paint. Then I removed the mount, cleaned
the ground clamps and reinstalled it.

I fished the cable down the windshield side pillar. The trim panel should be
removable. I used a long piece of baling wire as a fish tape. There were access
holes in the metal under the plastic trim. The wire ended up under the dash, right
where I wanted it. I remember seeing a wiring harness coming down the same way.
Some other things to watch...get yourself some silicone grease and some anti-oxide
lube (I used Permatex Anti-seize from an auto parts store). The silicone grease
goes on the threads of the plastic cap and on the o-ring that contacts the
roof. The anti-seize goes on the bottom end of the whip, the allen screw threads
and the threads of the threaded stud on top of the plastic cap. Be generous with the
stuff and wipe the excess off after you get it all together.
The idea is to prevent capillary action which will
suck water (here in New England, they put salt on the roads in winter) up into the
threads and into the socket that holds the end of the whip. If you don't do the
above, the first thing you'll notice is SWR problems and the next thing you'll
notice is that you can't undo the set screw :-) When you finally get it all loose,
you'll find the end of the whip is all corroded by the water that seeped into the
socket.
Do a good job waterproofing it and your antenna will outlast the car.
Cheers,
Peter

Yeah, I went to Ham Radio Outlet as soon as they opened the next day.
They were extremely helpful and promised to spread the word among their
stores. I also called "The Radio Place" in Sacramento. The thieves were
most likely NOT hams (how many of you know fellow hams that would break
into a car and steal equipment? I don't), so they will probably try to
contact somebody to find out what the radio's worth.

Also good ideas, also done. I went to surplus dealers in Santa Clara
and Mountain View; all were sympathetic and helpful.

Good point, Bill. Although having my ICOM stolen wasn't the end of the
world for me, I believe that making it difficult for thieves to get away
with their crime is well worth the trouble. If they are caught, or if
they cannot sell their stolen goods, perhaps it will help cut down the
ripoffs.
Again, if anybody comes across someone selling an ICOM 2 SAT handheld,
serial number 4220, please contact me or the Sunnyvale Police. The radio
has a no-name 12V battery attached, and no bottom cover.
Thanks to all!

Well, my brain has forgotten the exact amount of capacitance we needed
but basically we put a varicap diode across the transmit xtal and ran
audio from the mike to it. The diode was chosen to provide about 5 KHz
deviation at full audio. 'course, that made the rig an fm rig.
Details forgotten with the passage of time.

According to the manager of my local R.S. store, Radio Shack generated
a list of all of their customers sorted by amount spent at R.S. in the
previous year (dollars, not hours ;-) ). The top 10 million? people on
this list received preferred customer cards.
