To: [e-mail]

I'm building a new house and am planning to use CATV (cheap!!) cable to get
to the towers (abt 300' from house). Many people say to forget abt the
mismatch. There is also a company that sells expensive 75 ohm to 50 ohm
transformers. Has anyone made a simple and inexpensive transformer to convert
a 75 ohm impedence to the 50 ohm the rig and antennas want to see?

Hi Ken, what kind of coax? What frequency of operation? If you expect to
use 1/4 in. dia. stuff on 2m, you might as well forget it. However, if
you are using CATV hard-line on 80m, you are in pretty good shape. Please
give us some more details.

Yeah, and now I see that Rockwell/Collins has licensed the Japanese receiver
maker AOR, which uses a Collins mechanical filter in one of its HF rigs, to use
a "Collins inside" logo.  If Rockwell was REALLY smart they'd do the same thing
for modem chips...

You're confusing not being able to use the machine with not being able to
use the frequencies - these are not synonymous. Since the machine is private
it has a coded squelch. Feel free operate simplex with others either on
the input or output when the repeater is not in use (you'll have to monitor
the output).

Some folks are under the mistaken impression that repeaters are public
property, but of course, that is not the case (and  has  been affirmed
by a California court).

Rather than trying to invade or force closed repeaters to open, why not,
instead, ask yourself why closed repeaters exist?

If you WERE successful in opening a closed machine, would any of the members
want to talk to you?

I'm all for banning any new repeaters. Encourage more simplex operation.
I can remember when L.A. had only one repeater (K6MYK - Art Gentry's AM
machine up on Mount Lee, Hollywood Hills; How is Art? - heard he was in
the hospital).

I've since left VHF for HF CW. Love it!

Subject: Nicad Batteries - The Offical Word
Newsgroups: rec.bicycles.tech

Awhile back, John Stevenson of MBUK emailed me asking about the "memory"
effect in nickle-cadmium rechargable batteries. I recently acquired
an engineering handbook published by Sanyo, maker of "Cadnica" brand
nicads.  I thought the information would be of general interest.

In the following, "C" is the amp-hour capacity of the battery.  For
example, if you have a 5 A-hr battery, a charging rate of "0.1C" is 0.5A.

To: [e-mail]

I have a basic DJ580T setup with:

    EDC-24 charger (8.7v 70ma) rated for EBP-14/16/18 batteries
    EBP-20N 7.2v 700ma battery (came with the radio)

I purchased an EBP-24S (7.2v 1500ma) Periphex battery pack which did
really well for the first six months that I owned it.  I charged it
with the EDC-24.  Now the Periphex pack doesn't last very long on a
charge (less than the 700ma battery).  Has anyone had similar
experience?  I noticed that Alinco sells an EDC-49 battery charger
that is rated for the EBP-20/22/24N, should I get this to charge the
pheriphex battery?

Thanks for any advice,
Charles

Subject: NMO Permanent mount in Plymouth Voyager?
To: [e-mail]

I sucessfully completed my first permanent NMO installation over the
weekend in my Jeep Grand Wagoneer.  Before I installed the mount on
my Jeep, I asked around and found someone who had done it and he gave me
instrucations about how to proceed.  My wife was so impressed with the
professional-looking results that she wants one in her 88 Plymouth Voyager.
Upon asking around, however, I have heard that the Voyager (and Caravan)
models have double walled construction that may cause severe
installation problems.  Before I drill a 3/4 inch hole in her roof,
could some voice of experience please provide some guidance?  I am
interested not only in whether it can be done, but how to route the coax
thorough the headliner, if it can.

Thanks,
-Steve

Subject: Radio Shack DSP
To: [e-mail]

I bought the RS DSP unit several weeks ago. Its strongest point seems to
be removal of hetrodynes and other continuous tones from audio. I use it
to help clarify the AM voice reception on international broadcasts with my
Japan Radio NRD-535D receiver. (That receiver has rather muffled reception
of voice, normally.) While the DSP is not a miracle worker, it does do a
nice job of clarifying international SW broadcast audio. It also does a
pretty good job with QRM on some amateur SSB transmissions

I hope that helps.

This would get even more tedious in a two or three person QSO, but
may be a good idea in a roundtable, esp when people have a hard time
remembering who gets it next.

Subject: Test session wierdos
To: [e-mail]

Somewhat along the lines of the thread about the color of the 610 forms, we had
a guy at our test session this past weekend who refused to sign the 610 because
of the wording of the certification that all the info was correct, etc. etc. We
told him the FCC probably wouldn't accept the form without a signature and the
guy got all steamed about his rights, etc etc. He got real belligerent and
disruptive so we asked him to leave. He did (luckily) but not before a lot of
very loud foul language and threats to sue us all etc etc. Anyone else ever
have something like that happen in a test session?

I'd be interested to hear some of the stories about VE sessions. We've had a
heart-attack scare (during a code test ;-) ...the guy was OK after popping some
nitro pills), a guy who wierded-out during another code test (he was real
nervous...listened to the warm-up, stood up, threw off the headphones and went
into a long tirade about how he was 43 yrs old, a Mensa member, had worked on
the code for 2 years and just didn't understand why he couldn't get it. He got
real agitated and left the room...we were worried he was going to shoot himself
in the parking lot), and some who argue about the results and just can't
believe they didn't pass. On the other hand, we've had people who were so happy
to pass they start hollering and jumping around (we give our tests in the local
public library and they get a little upset at people making lots of noise).

I guess it takes all kinds. Keeps things interesting, for sure.

Anyone else have any interesting VE stories to add?

That only works if you 1) ID at the end of every transmission or 2) always say
something every few minutes.

If I'm in a QSO with 5 or 6 people and they get involved in a discussion that
I don't have anything to contribute to at the moment, I keep my mouth shut
until I have something to contribute.  I'm not leaving the group, I'm just not
speaking until I have something to say.  (Actually, lots of hams should learn
the "If you don't have anything to say, don't say anything." rule.)

The most efficient way in this case to obey the rules is to say "AA5AA for
ID".  It gets the message across, causes minimal interruption to the
QSO in progress and allows you to get up and leave in the next 10 minutes
if nature calls, someone knocks at the door, etc.

If you have to ID just for the sake of rules compliance, it's the most
efficient way to do so.  (Unless someone invokes the "Why else would you
ID?" bandwidth waster.)

It may be superfluous to say "for ID" when you are saying something else in
the transmission, but it's just common courtesy to say "for ID" when you are
just ID'ing.

From: (null)
"Nickle-cadmium batteries have a "memory effect" in which the voltage
drops by 2 levels during discharge after shallow charge/discharge cycles.
In application when discharge end voltage is highly established, apparent
decreases in capacity and operating voltage are shown."

A graph shows a series of discharge curves (voltage versus time) for a
battery under the following conditions:  (1) Fresh battery, (2) First
discharge after 100 cycles, (2) Second discharge after 100 cycles,
(3) Third discharge after 100 cycles.  The "cycles" consist of a 0.1 C
charge for 10 hours followed by a 1C discharge for 10 minutes.  The
"discharge curve" is measured after a final 0.1C charge for 16 hours
followed by a discharge rate of 1C.

The four curves are almost identical.  As near as I can read the graph,
The first discharge after 100 memory cycles drops to 1V after about
63 minutes, compared with about 66 minutes for the fresh battery.

Bottom line:  Yes there is a memory effect, but it is very small and
not worth worrying about.

Other Nicad tidbits:

Charging:

"As long as a Cadnica battery is charged at an input rate below the
specified value [typically 0.1C] internal gas pressure remains at a
low level.  However, heat generated by gas recombination causes a rise
in cell temperature.  When overcharging is repeated often, heat
deteriorates the cell and shortens its service life."

So don't overcharge excessively.  It's OK to leave your battery on the
charger overnight (up to 18 hours or so if the battery was well-discharged)
but don't hook it up to the charger and go away for a week.

(Actually, my lighting system is supposed to have circuitry to prevent
overcharging, but I don't depend on it.)

Discharging:

"The number of cycles Cadnica batteries can withstand depends on the
depth of discharge...  When the cell is discharged to a greater depth,
the number of cycles decreases."

Some folks have recommended that occasionally you intentionally
completely discharge your nicads to eliminate the memory effect.
The above implies that that's a bad idea.

Storage:

"Cadnica batteries can be stored at temperatures ranging from -30 degC
to 50 degC without essential deterioration in performance.  The
organic materials, such as gasket or separator, may deteriorate or
become deformed at high temperatures during prolonged storage.  Thus
it is recommended that Cadnica batteries be stored at temperatures
below 35 degC if there is a possibility of prolonged storage
surpassing 3 months."  [35 degC = 95 degF]

"Either charged or discharged Cadnica batteries may be stored
indefinitely.  ...  Though the capacity is recovered with a couple of
charge/discharge cycles in either case, the capacity of a discharged
battery is more quickly achieved."

Unlike lead-acid batteries, nicads are perfectly happy being stored
in a discharged state.  In fact, they prefer it.

"Batteries should be recharged prior to use after prolonged storage."

The reason for that is that various cells in the battery can lose their
charge at different rates.  If you then use the battery without
recharging, the weakest cell can become reverse-charged by the other
stronger cells.  That can kill a battery.
