actually, the two major international QRP groups, QRP ARCI and GQRP use 10
watts for SSB, and 5 watts for CW, since they are equivalent in "talk
power".
It is the ARRL who is the odd man out, as most local QRP clubs follow QRP
ARCI in North America, and G-QRP in the rest of the world!

Frank,
I just check the resistor strip from K2 SN 5428 which I am building for
another ham.
There are normally 95 resistors on the strip. The first two resistors are
220 ohms, and there are 9 resistors from the strip that are to be used in
the Part I assembly.
Of the 86 resistors that should rem

Hello
I installed K6XX tuning indicator (SMD type) in my K1.

Everything is OK only except minor problem.
I notice low frequency hum when I make keying. If I
disconnect Pin-3 of tuning indicator then I do not
notice this hum.

would say that the performance is very good, but not as good as the K2 in
several areas.

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
thin foil which is a bit loose from the glass.
Is it right to leave the thin foil on there, or should it be taken off. I'm
not sure.
Thanks in advance.

When trying to tweak my KX1 I noticed that most of my plastic tools were too
weak, and metal tools changed the setting.
Looking around I found a few that seemed interesting.

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

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...

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

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.

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
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

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?
