The article appeared in the February 1992 issue of QST on page 40.
Unfortunately, I have misplaced my February issue, while other people on the

	I'll see if I can dredge up the information, but the "memory"
effect often associated with NiCd batteries is mythological.  They
*never* had it, though certain practices caused it to appear that they
did, infact, "remember" their charge-discharge cycle.  If I can find
the long articles, complete with old and new exerpts from battery
manufacturers, I'll post it in all of its lengthy glory.

	The bottom line is: don't *don't* *DON'T* discahrge NiCd
*packs* completely.  Never.  Not even once.  Why?  Because there is
inevitably a capacity difference between cells.  One may be completely
discharged before another.  The one that augers in first is then
reverse charged by the other, just-barely-alive cell(s).  This causes
formation of slender metallic crystals or whiskers bewteen the plates,
shorting the cell and rendering it unable to accept a charge.  It is
possible to "zap" them back to temporary life, by running enough
current through them to fuse the whiskers.  But the cell is henceforth
prone to doing the same thing again with only slight encouragement and
will never be very reliable.

	Single NiCd cells seem able to tolerate total discharge just
fine, but *will not* tolerate reverse charging.  So unless there is
only ONE cell in whatever gadget, don't ever discharge the device
completely.  Partila discharging followed by a proper charge cylce
will not cause a memeory effect; I've had packs last many years by
just being careful.  BTW, proper charging means never letting the cels
get very warm at all.  If they get hot, the water will evaporate out
of the cell, significantly reducing it's capacity and life.

	I *know* I have this stuff at home... I'll post it for the
net.

    All of this is true and good advice.  But there is a BIG 
    difference between a "TOTAL" discharge and recharging after every 
    partial use.  If you use NiCads only a small percentage of their
    capacity, and then recharge and repeat this same pattern frequently,
    they will soon no longer be capable of much more than the "partial cycle"
    you have been using.   This is easily demonstrated.  I have seen it.
    I have manufacturers brochours that describes it and tells to use
    the battery to its fully rated service interval periodically.

    This to me is a "memory".

The general summary and I've heard this before from other independent
people, is that you're extremely unlikely to see memory effect in any
piece of consumer electronics.  Memory effect occurs when the charge/
discharge cycle happens over exactly the same range.  This was noticed
when automatic chargers were used that noticed when the voltage dropped
exactly to a given point, turned on until the battery was charged, and
turned off.  Very precise, and thus the typical engineering used in things
like the 1960's space program.   Unfortunately not the best for NICADs.

The fact that people believe this can happen would not be a problem, except
that the myth is followed by the suggestion that you periodically let the
battery drain completely either under normal load or (horrors) via some drastic
action.  About the worst thing you can do to shorten a NiCad batteries life
is to let it drain all the way down.  Longest life occurs when you recharge
them when you get the first indication of low battery.

The author of the article is actually on the net somewhere, I've corresponded
with him.

The problem you describe is more of an issue with intercoms than with
a single handheld radio.  I agree that DCs use much more current relative
to other brands, but this is for the mic preamplifier.  From memory,
about 3 DC's into a Flightcom IIgx was about the max for standard
batteries (9v).  I use a 12V gel cell as an external aid on mine and
only charge the big battery once a week instead of buying new alkalines
every other flight.

:-(  Simple solution, unplug the mic connector!  Right!

From: claude@color3.UUCP (Claude Goldsmith)
In my experience, the problem is that the individual cells which make
up a NiCad battery pack may not all arrive at 0 charge simultaneously;
each cell has a slightly different capacity.

When you completely discharge a NiCad battery pack under that
circumstance, you will end up reverse-charging those cells which
discharge first.  This leads to shorted cells.  I don't KNOW why that
is so; I'm not a chemist.  I've been told that the reverse charging
causes some sort of crystal structure to grow inside the cell which
ultimately (over many cycles) shorts the cell; preventing it from
being charged.

I was told by people who I believed (at the time) to be experts
"If you want to completely discharge a NiCad pack you should
discharge each cell individually".  This is not easily accomplished
with today's sealed battery packs.

In one sense a motor differs from an engine in that a motor converts one
form of energy directly to another - an engine converts using at least one
intermediate form of energy. Thus an electric motor directly converts
electric to mechanical energy; an internal combustion engine converts
from chemical to heat to mechanical energy.

However, in common usage, a motor is a device that provides the
motive force for a vehicle. In this sense a car engine is its motor,as
is an aeroplane's engine. But an electric motor can never be
called an engine.

I used to be fussy about this, but I realized it doesn't really matter.
When someone refers to the motor in a car or 'plane, we all know what they
mean. I don't think it serves any purpose to nitpick about it.

Now perhaps we can discuss the difference between 'mold' and 'mould'. One
is a fungal growth, and one is a shaped vessel used for forming objects from
a solidifying liquid - but which is which??? :-)

I had a situation similiar to Jim's a couple of weeks ago.  Flew to
Indianapolis to deliver a computer to a friend.  While I was there (a
couple of hours), the 182RG got a coating of about 1/8" of frost on it.
Decided to have it deiced before departing.  While I had no doubt that it
would fly with no problems, 

	1.  The temperature was 19 deg on the ground, and it was no
	warmer aloft.

	2.  I was by myself, and the tanks were about 3/4 full

I decided to deice it to play it safe.  Hauled it into a heated hanger, and
about 45 minutes later, I was on my way (after making sure that all the
water had evaporated out of the control surfaces and their fittings).

Remember, there are bold pilots, there are old pilots, but there are no
old, bold pilots.
