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.
16 sty 2021 · [Charlie Morris (ZL2CTM)] recently did this with a simple antenna tuner, a device used to match impedances between a transmitter and an antenna. As he explains in the first video below, his...
Automatic antenna tuner using an Arduino by PA3HCM. The Arduino board is a fantastic tool for rapid prototyping, and can help radio amateurs in lots of homebrew projects. I wanted to demonstrate that it is very easy to build an automatic antenna tuner with the Arduino. http://www.pa3hcm.nl/?p=336.
This is an update to the ModularTuner project, a project to make available an easily homebrew, customizable antenna tuner, and eventually to turn this into a steerable phased array antenna. You can find the project at. http://www.github.com/profdc9/ModularTuner.
Get maximum power to your antenna by learning how to hook up and use a tunner to properly "trick" your rig. A remote antenna tuner. Interesting project to remotely control, using a servo control circuit, a common commercial antenna tuner by N30X. W8ZR High-Power Antenna Tuner.
1 lis 2020 · A Simple Antenna Tuner for SWL Radios. by Steve Allen, KZ4TN. After reading 13DKA’s excellent review of the Belka-DSP on SWLing.com a few weeks ago I knew I had to have one! The size, features, and performance of the Belka-DX (latest version of the Belka-DSP) is phenomenal.
