KAT3 freq range
Locked

I have looked at the manual and on line and I haven't found the tuning
range of the KAT3 tuner. Anyone have this info?

The schematic shows the values of the inductors and capacitors. From those values, you could easily determine whether or not it could match a specific impedance at a specific frequency. However, specifying SWR "tuning range" is difficult, because a given SWR can present a whole range of impedances at the tuner. If you really wanted to, you could plot the impedance range on a Smith Chart for each band. From that, you could get an idea SWR range. Perhaps one of the Smith Chart applications could automate that. It could also be done with a spreadsheet.

The answer to the question is a fairly large dataset, or a series of
multiple trace graphs, or a math utility that if you give it a On Thu, Jan 13, 2011 at 10:04 AM, Scott Ellington < [hidden email]> wrote: > The schematic shows the values of the inductors and capacitors.

Exactly.

Approximately up to 10:1 on most bands. Less on 160M and 6M.

No doubt Eric or Wayne has done that calculation.
