Don,
Thanks for the information. I will follow your advice. I know the wire
antenna is not the best but for the time being it's all I can come up with.
I also think I will go ahead and install the KAT2 since it is complete and
ready for installation and would solve some of my impedance issues.
85/17 or 43/9 is a good multiband antenna for use with a KAT2. I have
found my KAT2 capable of matching loads that I couldn't match with my
stand-alone QRO tuners. I have a K2/10 with battery and KAT2 for all
kinds of portable uses including my RV. I have a separate
KPA100/KAT100 in an EC2 that
Hello,
I think I might have a problem with K2 7109. I arranged to call another K2
owner on 40 meters and was not heard, additionally I did not receive his
call. So I'm not sure if it was propagation or my radio. What makes me
wonder is I have called on the SKCC Elmer frequencies with no
difficult.

Hello Mike,
The station I was trying to contact is 425 miles to the Northwest of my
location. 40m propagation seemed good, I was receiving other stations on
40m. I'm using a long wire for now and was putting 3 watts out according to
the power reading.
I don't have a watt meter but MFJ has a QRP
Ed,
First trial, connect a dummy load and do a TUNE - what does the K2
display tell you? It should be close to the requested power and with an
SWR of 1.0. If your dummy load is the Elecraft DL1, measure the voltage
at the diode and calculate the power output from that.
The above will tell
Don,
I do have the Elecraft dummy load so I will look into that. I will also try
going to 10 watts and work down.
I don't have an antenna analyzer at this time, sounds like something else I
will need to pick up.
I'm using a 32' wire with a 16' counterpose which is hanging out an upstairs
Ed,
A 32' wire with a 16' counterpoise is not a resonant antenna on 40
meters. It will not load well unless you have an antenna tuner to
turn it into 50 ohms. I have a KAT2 in my K2 #1239 to allow me to use
miscellaneous antennas. I am assuming that by your calling it a
counterpoise it is not
Ed,
As an alternative to the antenna analyzer, use TUNE on the K2 and adjust
the antenna tuning unit for the lowest SWR possible - note what that is
- and if it is 1.0, the K2 will indicate the power output properly.
Note that the base K2 uses only a diode detector. What that means is if

Thanks for the advice. I think I'm getting out okay. I hooked up my
MFJ-267 Watt meter dummy load and when I have the power set to 10 watts I'm
getting close to 10 watts forward but the reflected is about 5 so that tells
me the antenna is the issue. I have a KAT2 ready to install so I
Ed,
Hanging it out the window is the best idea.
That counterpoise is the other half of your 40 meter antenna - so if
you want best results, put it up in the air at whatever height you can
manage - treat it like an antenna radiator - because that is exactly
what it is.
Caution: an antenna
