Rich,
I would like to second Ron's (AC7AC) comments about tuners. Personally I
would stay away from 'T networks' for use in antenna tuners, and use the old
fashioned link coupled form of balanced tuner. T networks can be mistuned to
provide a 50 ohm load for the transmitter, but not deliver much
I have now operated K2 S/N 4751 for about a month and everything seems to
work pretty good. I am mainly a PSK and RTTY operator and I would like to
know if others have had the same experience about the K2 with PSK.
The narrow band width with PSK requires a stable radio. I see sporatic cases

OK, I wanted to build a plug-n-play off-center-fed
doublet for Field Day to match my K1 (40-30-20-17) /
KAT1 / solar powered portable station. This aerial
would be much like the old Fritzel, with some
customization for my purposes.
I reasoned I could fiddle with the offset (and maybe

A balun will probably work
okay, but they become unpredictable when the SWR on the line is high, as it
will be in your antenna.
I use a classic Zepp and found this out first hand! A 4:1 balun might
not give a true 4:1 change in that case or could
I know most of you don't feel this way, but I have finished installing
the large toroids for the KAT100 and the board is so pretty I want to
hang it on a wall as a picture.
Well, not as nice as the pin-up calendar on the wall, . but almost.

Steve,
Didn't your Mom warn you about sniffing solder fumes??
IMHO -- it does make a pretty looking piece of gear :-))

I agree!
I hate winding those things, but I love to veiw the result. It makes me
proud of myself.
I to love Toroids and how they look after they are done. I was scared to do
them in the beginning, but now from time to time I get Toroiditis. I would
love to wind a toroid or two. To do that, I would have to sell the
K2/100/KAT100 and start all over and that doesn't quite work out in
Years ago the Apple Computer company had the framed prototype of the
Apple 1 on their wall like a picture. With a note under it saying OUR
FOUNDER. Been some time, not sure if its still there.

Here's a poem I wrote to inspire kit builders on this topic. I first
posted it six years ago, when we had just started shipping the K2:
that donut shape you're wielding
is a wondrous thing to wind
and also is self-shielding
thus yielding peace of mind
Builders kept asking whether they

I would like to hear some comentary about addimg 160 to my K2.
I have never worked 160 because of the severe antenna requirements.
What does the reflector think?
I wonder why 160m is an option on the K2 other
than the fact that it
would a crystal set ant like this

This drift is discussed in the ReadMe file of one of the PSK
programs (WinPSK, MixW, TrueTTY, etc.). If both have snap and/or AFC
and the sound cards are off a little, then one slowing creeps up
the band as each station adjusts to the other.
