Just a clarification.
While the Battery subclass is limited to 5W, the Alternative Power Bonus
is not. We were running 100W on Battery for one of our stations using
Solar Panels as the power source.
I also agree that the Battery subclass should allow more power. There
would still be the QRP

Gentlemen,
I had a similar experience with my KX1. I could hear signals fine when
aligning and the screwdriver was touching the trimcap, but very little as soon
as I pulled it off.
I didn't have desoldering equipment available and knew that I had tried to do
some adjusting to my L1 so that
I appreciate your input, CPT Neve. My problem may be different though. I
solved the mystery of the signal getting louder when I touch it via a
combination of using a completely non-ferrous adjustment wand and the

I have completed my basic QRP K2. I have the KAT100 tuner. My
question is this...
Can I use the KAT100 tuner in QRP mode without adding the 100 Watt
Amplifier? Or should I build the 100 Watt Module and then build the
KAT100 Tuner?
TIA

The KAT100 uses a cable to connect it to the K2, and that cable plugs into
either the KPA100 AUX I/O or the AUX I/O connector in the QRP lid.
So the answer is yes if and only if you have the KIO2 installed in the QRP
lid. If you do not have the KIO2, then you will have to wait until you
build up
John,
There is an alternative to the KIO2. The KAT100 uses only a few control
signals from the K2 and doesn't use the RS-232 interface. You can easily and
inexpensively build a replacement for the control portion of the KIO2. Look at
the circuit diagram for the KIO2 and for the KAT100

Can someone tell me the official definition of QRP Power Level? Is it 5
watts for voice and CW modes? I notice that many contests have a QRP class but
they do not define QRP power and I cannot find it on ARRL site. Thanks,

Kent,
There is no 'official' concensus that I am aware of.
Each contest should specify what they consider QRP power levels in their
contest rules.
CW is almost always 5 watts, but SSB is sometimes either 5 watts or 10
watts - the ARRL seems to consider 5 watts as QRP for both SSB and CW.
Check
5 Watts CW output from the rig. At one time I heard something about the
level being 10 or 12 watts PEP for SSB but I've never run across any
confirmation so I believe the official definition is 5 watts period.

Hi Kent
I went through this a while back.
QRP for every contest I could find is spec'd at 5w out,
cw or ssb.

Subject: [Elecraft] QRP Power
I've sent Bob and Kent a few examples of QRP contests (and ARRL Sweepstakes)
where participants define QRP as 5W CW and 10W SSB.
Since this in an Elecraft list let's see what the Elecraft QSO Party rules
have to say about QRP power levels...
When using QRP calling frequencies, use QRP power
QRP-ARCI uses 10W PEP for SSB.
This is used for their one SSB contest and in their awards.
I will agree that most organizatons use 5W period, so it pays to always
check the specific rules.

The accepted standard is 5 watts CW, 10 watts PEP phone.

Tom's email can be read to imply that ARRL Sweepstakes defines QRP on

I'm building K2 # 3612 . Question about the led diffuser.
The back side has a thick foil. The front side is much more thinner, a milky

Is it right to leave the thin foil on there, or should it be taken off. I'm
not sure.
Thanks in advance.

actually, the two major international QRP groups, QRP ARCI and GQRP use 10

It is the ARRL who is the odd man out, as most local QRP clubs follow QRP
