To: [e-mail]

I am too, sort of. I am 33, and have been licensed since 1983. I was
enthusiastic at one time, got my Extra, got lots of equipment, but also
have a family and a job. I would love to experiment with digital modes
at 902, but I have to be content to make the multi-DSP card work before
Christmas. Besides, I get paid for making the card work so I may be
able to buy radio "goodies".

I have been interested in radio since the next door neighbor messed up
Saturday morning cartoons. He helped develop "tele-text" systems for
broadcast TV. He also went "silent-key" last year, thanks to cancer.
My other mentors and Elmers have also either left radio or died.

There are some hams still on the leading edge, likes of Phil Karn and
Cliff Stoll. They are doing ham radio, but also good work on the edge
of communications and computer security. Some others are up there, too.
(Sorry, don't know all of your names.)

Keep posting, your ideas may help bring the dream of others to life.

Subject: Mods to use AMTOR/PACTOR on Atlas HF rigs?
To: [e-mail]

       All,
    I'm in the process of trying to get on AMTOR (and hopefully
       PACTOR once I get the FW upgrade from MFJ) and have had problems
       while using an Atlas 350 (or 210). I can't seem to link up with any
       stations on 20 while they're calling CQ (FEC B). I suspect it's the
       AGC timing of the Atlas (which is not externally defeatable). Can
       someone tell me if this is common on old rigs due to their slow
       response time?
       (BTW, I have no problem copying mode "A" or "B" transmissions in
       "monitoring" mode, using an MFJ-1278 TNC, running rev 3.3 FW)
       Thanks

I was looking through the GOPHER a little while ago and came up with
post where someone has made a MORSE CODE program that runs on UNIX
boxes and its location.

Its located at HANAUMA.STANFORD.EDU <36.51.0.16> morse.shar is the
file name

I have never seen this posted before and according to the post ITS FREE
shareware.

Milt's advice is good. The manufacturer's advice for long term storage
of NiCd cells is to store them *individually* totally discharged. No
chemical activity takes place in a totally discharged cell, so they
shouldn't be harmed by long storage. However, if the cells are connected
in a pack, then follow what Milt said. You can get a reversed cell as the
pack self-discharges in storage. There's always some leakage current in a
pack even if it isn't hooked to a load. Recharging every couple of months
should keep the pack alive during storage, but of course you're eating
up cell life by cycling them.

The guy who maintains the Hams on Internet FAQ? I tried 3 times to Email

And that's the problem.  Gateway operators don't know.  It's not clear, I
think, whether I would have violated FCC rules if I sent you an illegal
message originated in the Internet.  What if I thought it was going to an

  Depends, I guess. In Colorado, the freq coordinator has seen fit to
  set aside a few frequency pairs for Special Event or Emergency
  repeaters. Thus, some public service minded people keep portable
  repeaters crystalled up on those pairs.

I have a briefcase repeater that I carry with me for boonie ad hoc
repeater use and for use at hamfests. The trick to cause the minimum
of disruption is to use low power, mine's 2 watts, and use CTCSS access.
The biggest no-no is to operate inverted from the bandplan. This can
cause real trouble. In most of the country, a UHF portable repeater like
this can be a big help at outdoor events while causing almost no problem.
However, sometimes there's a local machine on the same pair and you can't
use your toy. That's OK, just use the big machine. My portable is on
the same pair as my big machine, so when I use it locally I can only
jam myself. :-) It turns out to be useful inside some of the big
convention center halls where hamfests are held, and where the big
machine doesn't penetrate too well for handheld users. It's also
useful outside in some of the main repeater's coverage holes.

Getting coordination for a portable repeater is impossible. But do
use the repeater directories, and *listen* before activating a portable.
That in essence is doing your own coordination. If you're upright on
the same pair with a distant machine, you won't cause much, if any,
trouble to it's regular users as long as your repeater is CTCSS, uses
low power, and *your* users do the same. The biggest problem will be
your users triggering the distant machine, if it's carrier operated
and a bunny rabbit (all ears). The secondary problem may be your
machine's output covering the distant machine for some ham near you
trying to repeater DX. You should be alert to these situations and
be ready to shutdown at a moment's notice if problems arise.

To Rick, my portable is a conventional repeater with duplexer, in a
Zero Haliburton case with a gell cell, but that may not be the best
solution for outdoor use. An alternative is to use two frequency agile
radios (a pair of older HTs would be fine), a controller, and separate
antennas. With decent spacing, vertical separation preferred, you can
have a system you can plop down on any locally vacant pair by just turning
a couple of knobs. Retuning a duplexer in the field isn't fun, but a couple
of notch cavities can be whipped on frequency fairly easily, and will ease
the antenna separation requirements.  Low power eases the desense problem
too. Using ammo cans to house the radios is a good idea, one radio to a can.
That gives the extra shielding you're likely to need.

It was those mostly grey and balding men, whose voices I heard on MY home
made short wave radio, that inspired me to be one of those voices myself...
errr...TRY to be one of those voices.

Yes, there is a lack of intrest, in home making anything...less reason maybe.
In order for a radio to be compatible to everyone elses, it has to be SO
high-tech, that one can't just go whip up a 1 tube rig and expect a whole lot.

Well....almost.....

Theres  a very small bunch of us who still dabble with older technology, and
we stay in contact (now) via this Internet.
I have several 1 tube transmitters (all out on loan to those who can't get
over such a thing ) of home made construction....and there are two young guys
who almost live here,now, who are making 1 and 2 tube rigs...one has a 3 tube
receiver we put together out of salvaged parts.
(you should have seen the look on his face when 1st turned on and he tuned in
on someone calling CQ)

Yah...things have changed.... but theres a few of of preserving the past still.

Its not gone....just well hidden under the noise   :)

What if someone used a modified HT to transmit on the R/C frequency and
jam the sucker until it crashed.  Then who would be liable?  I've seen
people use Radio Shack CBs to jam those 27 MHz R/C cars.  Knocks 'em

Perfectly true Steve, but under US rules the work has to be done
by a licensed technician, not by the CBer. So asking for instructions
on how to make internal adjustments at home is where the problem arises.
Now in the perspective of the general lawlessness of CB, this is really
a reasonable request, but it got crossposted to the amateur group, and
that was inviting flames from the armchair lawyers. In truth, most
amateurs couldn't do this job properly to FCC specs because it requires
test equipment most of them don't have. Expecting a CBer to both have
the skills, and the test equipment, is a bit much. To do the job right,
you need a calibrated service monitor and a spectrum analyzer.
