NettetThe variable link with a series capacitor to ground should be enough; the additional tuned circuit in a link-coupled tuner will just waste power. The capacitor tunes the link to resonance. That's all the tuner you need. To tune the transmitter, first run the link all the way out, and with the transmitter in tune mode, dip the final. NettetIt uses link-coupled coils and differential variable capacitors. The "Transmatch", originally described by W1ICP, has been simplified in modern times and is now more accurately referred to as a T-Network matchbox. Nettet2. nov. 2024 · Home.

NettetThe link-coupled tuner is very flexible, can accommodate a very wide range of impedances and reactances, and, because it is possible to select the optimum LC ratio, is very efficient. I read the QST review of the MFJ 974 with interest and noted the high losses, incurred at some lower frequencies and impedances and in particular the high … NettetThe EZ-Tuner - The "EZ-Tuner" is a homebrew automatic legal-limit antenna tuner that covers all amateur HF bands from 160-10 meters.

NettetYou'll need some form of inductively coupled ("link-coupled") tuner to do this. The most popular of these at the moment seems to be the "Z-match" - it has good although not perfect current balance on the outputs. Most of the Z-match designs I've seen can be implemented with two variable capacitors, and one fixed inductor. There's a "two coil" Nettetbalun on the tuner output. Relocating the balun to the input of an unbalanced network does not help the balun do a better job and complicates tuner construction. The ideal balanced tuner would have a link-coupled floating balanced network. Nothing else will assure optimal transmission-line balance. The output network must be ground …
