My Home Made Link Coupled Tuner

I recently built a link coupled tuner and have had great success with it on 75 and 40 meters. I liked the idea of it being a more efficient transfer of power than using a balun. I use 300 ohm twin lead for my feedline so a balanced tuner is just what I needed. My Heathkit SA-2060 tuner did fine, but I worried about the balun heating up after long transmissions. If you are interested in building one, do a Google search for link coupled tuners, and you'll find an abundance of information. I intend to dress it up a bit with matching knobs and maybe house it to prohibit people from the temptation of touching anything while I'm transmitting. 73 for now, Jim WØHRF
