Well ARRL 160 is history now.
As usual, with the K2 I heard more than I could get to
hear me ;o) Evidently I heard and worked more than
some of the local contesters with other brand
equipment heheh.
Anyway I have a problem... I use the KPA100 with the
KAT100, and there may be no connection

Do not be misled by the fact that on CW the K2 transmits on the
frequency as displayed, whereas many of the oriental black boxes
transmit a fixed number of Hz (maybe 600Hz) different to the displayed
frequency to give the required offset.
I have encountered a similar problem with

As I start to use the new POWER I have, I'm noticing things. Take the

With the QRP K2, the sidetone sounds pretty good. Put it through an
external audio filter and it sounds even better.
With the K2/100, the more power I run the more low thumps there are on

Richard,
If your power output indication varies with frequency, then it could be that
the KAT2 wattmeter diodes are frequency sensitive.
BUT, I must ask - how do you know your dummy load is not frequency sensitive
as well, and what is the accuracy of your external wattmeter? Many
wattmeters

I've used that same wire in stealth indoor antennas at power levels as

Thumb tacks or push pins are FB. I prefer the white or clear push pins and
put a loop of the wire in a half hitch around each pin so it remains
tight.

The RF Probe that comes with the K2 will read the RMS value of the RF
voltage.
The RF detector in the DL1 will indicate the zero to peak RF voltage and the
display on an oscilliscope will be the peak to peak voltage.
It is normal for the power to increase a bit over time due to heating of

Season's Greetings to all,

of the Heil Handi-Mic with a K2. I must agree with the majority that the

therefore require special considerations when used

I'm trying to align the IF amplifier on my K2 SN5549.

When I look at the signal with Spectrogram I see very little if any

I am tempted to say that if you cannot discern a peak, just set the slug
between 1 and 1 1/2 turns down from the top of the can and be done with it.
If you are using Spectrogram, use a filter of 400 to 700 Hz in width and
