17 cze 2020 · I have one for my station, and am very well pleased with it. It replaced my MFJ-939 when I got an old Heathkit SB-200 amp, and it handles its output very well (about 600 watts max, usually run around 300-350 SSB or 100-150 digital).
The ZM-2 ATU is a simple manual antenna tuner that you can purchase either as a fun-to-build kit or fully assembled and tested. I’ve owned my ZM-2 for many years, and I believe every QRP field operator should have one. They do a brilliant job of matching random wire antennas and taking your resonant antenna to a non-resonant band.
A simple QRP multi-z antenna tuner. Easy to tune low-z and high-z antennas. Still not sure about how well it performs. Hopefully it will do ok for 80m, 40m and 20m band. I just got a nanoVNA so I will experiment with the number of turns on the inductor and the values of the capacitor.
Short video on the MFJ9201 QRPocket tuner. Rated to 100 watts. We repair the device, modify it, and test it.#survivalcomms
I decided to build a homebrew antenna tuner because I needed a passive pre-selector network to match an experimental end-fed wire antenna to my QS1R SDR receiver. Please Note: In the last version of my modified FRI-Match (diagram above), I replaced the 470 pf variable capacitors with 500 pf.
18 kwi 2020 · A well-designed Z-match tuner has a high Q and is more efficient (less lossy) than other types of tuners. The fixed inductor simplifies construction (no taps or rollers needed). Using a toroid inductor and some small poly-film variable capacitors, the Z-match can be built into a very compact package.
