If you use an amp with your K3, you will need a higher power ATU. I have an MFJ-993B 300 Watt Intelli-Tuner for sale. Unit is in like new condition with original manual. This is a great auto tuner, easy to use and probably one of the best units MFJ sells.
Unit handles 2 antennas, has lots of memory for storing settings of previously worked frequencies, and has unique features like “sticky Tune”. Check detailed specs on MFJ web site.
I am selling to buy a higher wattage tuner to interface with my amplifier.
Price $200 plus shipping. Contact me off net at jgschatz@verizon.net
