How to Use an SWR Meter Step 1– Affix one end of the coaxial cable to the transmitter output connector at the back of the radio. The other end should then be connected to the “Transmitter In” jack at the back of the SWR meter. Both connections should be screwed in lightly. Step 2...
use, while the adjustable power test mode allows users to tailor the meter's performance to their specific radio equipment. Whether you're a ham radio operator, a satellite antenna user, or a walkie talkie enthusiast, the SW-102 is an indispensable tool for optimizing your radio communication ...
This SWR-meter design has one big disadvantage: each time when SWR measurement is required, the device has to be switched from bypass to measurement mode. After antenna tuner alignment it has to be switched to bypass mode again. Real-time SWR monitoring is impossible with this type of SWR-...
3.CONFIG:Provides menu for configurations and extended functions: PC link, step size setting, suspend timeout setting, calibration, and software upgrade 4.SCAN:Pressing this control initiates a scan of frequencies of the selected BAND, Scan exits to impedance mode showing the 2:1 bandwidth and r...
Accurate Measurement:The SWR / Power Meter ensures precise measurements, enabling effective antenna tuning for optimal performance. Ease of Use:The SW-111 is designed for simplicity, allowing users to quickly test SWR or relative power on their CB radio. ...
Loftur Jónasson has updated hisPower and SWR Meterwith a more powerful processor and better display. Thefirst revisionof the meter used a Teensy ++ and a know to navigate menus on the display. In this updated version he upgraded to a Teensy 3.2 and increased the sampling from 200 to 1,00...
HOW TO DO IT The first thing to do is decide what frequencies we want to use the meter for. It is pretty useless to measure several Gigalitres of water with a medicine glass just as a few millilitres are impossible to measure with a flow meter suitable for Gigalitres. You wouldn't ev...

Over on his blog Anders J. Ørts has created a good writeup showing how he used the combination of anAirspy SDR with SpyVerter upconverter, SWR-Bridge and a noise source to tune his HF dipole for the 40 meter and 20 meter bands. If you’re interested we also have a writeup on do...
I no longer have an amateur radio license. The only time I have used a VNA to look at an antenna was when I made a demo with the Nano showing how it could be done. It's certainly possible to use it to make these measurements (and many many others) but judging on the comments I...
