Make sure that these washers are not chemically treated. I think some are.
This is done to neutralize battery corrosion.

Hello group:
Last night I installed new NiMH batteries (the Powerex 2700 MaH variety) into
my week old KX3 for the first time and set them for a 12 hour charge. After the
charge was complete, the KX3 PS display indicates a power supply voltage of
only 10.8 volts, which drops to well below 10.0
I recently purchased a Micro Keyer II from a fellow ham New in Box never
used. However, it has an Icom cable and I have a K3. Does anyone have a
spare K3 cable for a Micro Keyer II that they would like to sell?

I'm using Olivia/Contestia most of the time rather than MPSK. The possible

Aside from the transmit gains, the system is operating normally, and the
sound card is clearly recognized and in use.
Good. If 9 o'clock and all is good then use Don's suggestion and set alc

Chris,
With your soundcard gains at maximum, it is possible that the output is
being overdriven and causing distortion (they are not out of the
picture at all.
I suggest you reduce the soundcard gain to the range of 1/2 to 2/3 of
full which will allow more range on the SignaLink gain.

I'm also a MARS op, and have used the KX3 mobile for MARS ops. The
only issue I've found is making sure that the antenna is resonant.
I have been using my KX3 mobile for the last 2 months. RX is as good or better
than any other mobile I have operated and at 10 watts I may not be strong but
consistently get complements on the audio. Expect the noise blanker to be
improved in a future software update.

I have always heard that the rule of thumb for charging a
depleted NiCd of NiMh battery is to charge it to 140% of its
rated capacity. If you are charging 2700 mAHr cells at 200 mA,
then you will need to charge them for 18.9 hours.

Yes, the K2 transmit gain can change with the various bands. There is
some level of TX RF gain compensation in the K2 circuits, but it is not
perfect.
Because of the way the K2 controls power, setting the power first and
then bringing up the audio to produce that power output is a bit
iffy.
Another minor issue is that the audio drive will vary somewhat depending on
which audio frequency is selected. i.e. 600 hertz vs 1800 Hz. will not exhibit
the same energy to the radio. Soundcards are not flat, many rigs are not
either.
So if you set levels for one (if RTTY, pair of)

It's possible to reduce the input level to get the 10-th ALC bar to

Acutally NiMH cells have a Coulometric Efficiency of 66%, which means you

If your target cell were 2700 mAH, and it was dead, then you need to put

There are several reasons why the signal level can be different on the

I would guess that running Peak on the P3 and having the S meter on

Or does the same discrepancy you advised below exist? Peak and PEAK

Hi Matt,
If they matched it would be a coincidence. For example, if the P3 is

100 Hz wide. If the K3 bandwidth is 2.7 kHz, then on a wideband signal
