The AT-1000ProII has a large, easy to read bar-graph wattmeter that show forward and reverse power with two selectable ranges (100 and 1,000 watt scales) as well as an SWR meter. The AT-1000ProII will interface with many popular transceivers so you can start a tuning cycle with the radio’s TUNE button.

Like most Generic LDG tuners, the Z-11ProII can operate automatically, beginning a tuning cycle whenever the SWR exceeds a preset limit. It also features LDGs advanced memory tuning, providing 2,000 memory locations; when tuning near a previously used frequency it will recall the settings for nearly instant tuning.

2021年9月8日 · Most internal tuners can correct 3:1 SWR, and most of the external tuners will correct 10:1 or less. Of your SWR is greater than that, you not be able to find a match. If you have one, hook up a nanoVNA and see exactly what the SWR is on the 80m band, look at the smith chart which will show and ohm and capacitance reading.

It displays the sampled signals in numerous formats including Power/SWR, various oscilloscope type displays and a spectrum display. The sampled signals are obtained by demodulating the RF, like in a traditional wattmeter, and should therefore work on any frequency for which there is a suitable directional coupler with the appropriate voltage ...

2020年5月29日 · After installing the balun & the radio interface cable, the tuner now tunes and I get SWR readings of 1.42:1 on 7.240 and 2.1:1 on 14.270. I'd like to get the 2.1 reading down, so I'll keep working on it.

2020年7月21日 · Any energy that gets reflected back into the radio is typically identified by the Standing Wave Ratio (SWR) or the ratio of transmitted (forward) energy vs. reflected (reverse) energy. Here is why we watch SWR.

Standing Wave Ratio (SWR) is an important concept that describes how good of a match exists between a transceiver and antenna system. Recall that a perfect match corresponds to an SWR of 1.0, with higher values indicating some degree of mismatch.

2024年9月11日 · What is Standing Wave Ratio (SWR) and how does it impact your amateur radio antenna system? Is there really such a thing as “perfect” SWR and does it really matter? DX Engineering’s Michael...
