Greetings All,
Ok, I want to build a balun. It should be able to
handle 200 Watts RF (safety factor built into this
number), 80 thru 30 Meters (160M would be nice) and be
efficient. I want to use a Toroid to do this so it
fits inside an enclosure. My question is how small of
a toroid can I use and
My K2 has the 2nd latest chip set in it. It is a 3200 s/n. I have been using
it on SSB at 12W.
I have the audio compressor on max.
I have had hours of great QSO's so far. I know see an option to open up
the SSB filter on RX. I use the stock 2.2khz and I like the audio. I find the
1.8khz f
are four transformers to build.
73,
Geoff.

Well, I'm guessing here, but I think you'll need to
use ferrite to keep the inductance reasonable. You
also
All the hard work of balun design has been done in the balun kit offered by
The Wireman, Landrum S.C. (on web). I believe Amidon might also have Balun
kits and both fit the power range you want.
Typically, it is hard to get one balun to work 160m to 10m. See the Jerry
Sevick books, (Baluns and
Julius,
Off hand, without doing the design, I'd say something on the order of one
F-140-43 or two F-114-43. You can't get there with a T-XX-6; not enough
umph. Takes F-XX-61 at the least. Why limit it to 160 to 30 meters? The
BL-1 covers 160 through 6. See http://www.njqrp.org/balun/index.
