Subject: 10 M repeaters ?
To: [e-mail]

Having watched 10 FM over the last 25 years or so go from only one simplex
channel on 29.600 to the relative mess that it has become now is
unfortunate. Not only do we have people trying to run everyone off of 29.60
having a QSO (claiming that it's the "calling" channel) to dozens of
repeaters all in carrier squelch on the four repeater channels. There just
isn't room for any more repeaters on 10FM - the four channels we have
already are unusable. I don't know what it sounds like from the East coast,
but it is a mess from the west coast.

Some years ago, a group here in Oregon wanted to put up a 10 FM repeater in
carrier squelch. It was necessary to give live demonstrations to the frequency
coordinators as to why any coordinated repeaters had to have MANDATORY tone
squelch in order to receive a coordination for the repeater sanction.
Fortunately, S. California and some other areas have followed the same
requirements. Now if only the rest of the repeaters would follow the same,
we would be able to select just which repeater we wished to use, instead of
bringing up 10-15 repeaters at a time howling against each other.

Anyone considering "putting up a 10M repeater to help DX stations around the
country" - Please Don't - we have too many already. If you feel you MUST put
up a 10M repeater, PLEASE use tone squelch. Maybe someday we can obtain more
spectrum for repeaters and we won't have this problem.

C U on 10 FM,


Larry Johnson  K7LJ

NO!

Because your HT is not type-accepted for use in commercial service.

There may be no harm done, but its just not legal.

I have noticed that after solar flares and geomagnetic storms that the
propagation really gets good for the next day or so. Kinda makes you
not hate them so bad. 8-)

Subject: Nicad Batteries -- The Official Word
To: [e-mail]

I recently acquired an engineering handbook published by Sanyo, maker of
"Cadnica" brand nickle-cadmium rechargable batteries.  It lays to rest
some myths dear to the hearts of radio amateurs.  In the following, the
quoted material is from Sanyo's book.

Note:  "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.

The memory effect:

"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.
The second and third discharges show an even smaller difference.

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

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 (depending on the charger design, 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.

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.

I wish you the best with it, but i contend that the VFO setup is pretty
weak in comparison with the 78, and IMD rejection no better.  The PL scan
is nice, but only useful on very active machines that pass pl to the output.

Not bashing yer rig, my dad has one and likes it a bunch,

best of luck,
