I have an MFJ 1270. When I read about that clock chip I remembered having
seen something similar from Dallas semiconductor. It was a Dallas DS1216C.
Having access to one, I tried it and sure enough it worked.
It cost more than $1.98 I do not have the current US price.

I have gone to the Dayton Hamvention for the last 3 years, and have
dutifully filled out the ticket stub w/ name and address. Someone told
me that would get me on a mailing list to receive yearly flyers
(with the early-purchase ticket price) but so far no luck.
Is anyone out there affiliated with the group in Dayton which runs
this thing, and could get my name on the list for these flyers?
If so, please send me E-mail.
Thanks!

W2FMI's article in the Nov 93 issue of CQ postulated that an 80 metre
dipole fed with a quarter wave feed line (at 80 metres) would be the "worst
case" scenario for a multi-band antenna.
He goes on in the article to say that that a 102 foot dipole fed with 31
feet on ladder line would not present as high a voltage to the balun than
the previous example.
He then suggests that if one were to enlarge the second antenna to 160
foot flat top and 90 feet of ladder line, this would have yet better
efficiency on 160 metres and still present manageable (sp?) impedances to
the balun on 80 and 40 metres and above. I built the balun he suggested in
the articlebut have yet to try it; with a new baby in the house, spare
time is a precious commodity indeed!

Maybe this is how QRZ! figures out if someone has wholesale
pirated their CD. I have QRZ! but haven't even bothered to
check if my own data is correct on it, maybe I should :-).
I did find my FT-990 mod, which was posted to the Internet, in

Hopefully some of the amprnet listings are more reliable then WA4ONG
(44.62.0.1) here in Richmond. He goes down without warning and leaves us

KA9RLJ was the QSL mgr that HH2PK himself was giving out during the
WAE RTTY Contest. However, I don't have a card back yet after a month,
so I can't absolutely confirm.
The last issue or so of WorldRadio list HH2PK with a P.O. Box in
Port-au-prince.
I haven't tried the latter route yet, I am patient. He is really
not that rare. Worked him again during the RTTY Roundup last week.

One solution (which you may have thought of, or seen used) is to get a
magnetic mount 2 meter antenna, if your talkie has a BNC connector for
its rubber duckie. When you're in the locomotive, stick the magmount
up in the air a few feet from the window (away from immediately nearby
objects, a broad somewhat flat area is best, have antenna vertical).
(I would have thought the locos would have had built in dashboard radios,
and an AM/FM cassette player? :-) ). Anyway, this would get the RF away
from your body, and probably improve reception. A 2 meter antenna should
work reasonably well on radios on 160 MHz.
Wave to the guy with the camera, he likes to photograph freight trains and
box cars (he's my brother).

Have you checked out something like the Icom 2-SAT? Small size is
currently a major selling point, and some of the latest generation may be
even smaller; the 2-SAT fits almost anywhere. It has an option available
which allows coded paging, i.e., you can set it so the transmitting unit
must enter a set of tones on the touchtone pad to open the squelch of the
receiving unit. This is in addition to the CTCSS tone squelch which is
also available as an option. All this stuff fits right inside 2-SAT's tiny
case. Sounds to me like just what you want.

Subject: Site Security
To: info-hams@ucsd.edu
Gang,
I'm still a couple hundred articles behind because I was gone for 3
weeks, but I wanted to pass along the following with regard to repeater
site security:
Back in the late 70's I was considering installing a remote base to
facilitate getting into the L.A. area with a better signal. My plan was
to dig a small vault only large enough to hold the necessary equipment;
a vent pipe, leading from the vault to slightly above ground level would
be hidden by replanted brush. The coax would run underground to a nearby
tree which would have supported and hidden the antennas and solar panal.
Weatherproofing might have been a problem, but if the output power
was kept low no vent would have really been necessary - what little heat
generated would have been absorbed by the cool soil. But then this begs
another question: Isn't dry soil a rather good insulator against heat?
I never followed through with this idea; I wonder if anyone has ever
tried this, though.
Oh, anyone remember the Clegg FM-27? It was the very first transceiver
to cover the entire 146-148 MHz portion of 2 meters without requiring
xtals. I had the 27B model.

Not only can I not find this route, several other hams have asked me to

Any ideas of where it goes? I don't have a recent North American callbook

I guess since this is posted in the 'misc' group for amateur
radio, instead of the 'swap' group, that the poster is inviting
comment:
Wouldn't it be a nice thing if the OSU ARC, instead of using its
wind-fall to advance its own direct interests, could find a way
to provide a service to the ham radio community by, say, starting
a program of reconditioning equipment for school stations and
for young hams, and providing a source of vacuum tubes for others
who are doing the same?
Just a thought.

Subject : Re: Portable 2m Antenna for Mountaineering???
I have hiked several times with my Cushcraft 4 element 2 meter beam. If you
need the extra gain from a beam, it works great and is not overly bulky to
carry if you pack it into a tube or keep it in the original box. I use
wingnuts to speed the assembly process and have a portable tripod to mount
the thing. It's sort of home-brewed out of a similar design I saw in the
ARRL handbook. Anyway, like someone else said here, the AEA Hotrod is a
great little telescopic antenna that outperforms a duck several times over.
