Was bedeutet “F.S.” in der Skala meines Team SWR-1180-W Stehwellenmessgerät?
Hallo,
in meinem CB-Funk Stehwellenmessgerät “Team SWR-1180-W” gibt es die Bezeichnung “F.S.” in der Analog-Anzeige. Leider steht in der Bedienungsanleitung gar nichts daüber drin.
Weiß jemand, was das aussagt?
Danke für die Rückmeldung

I have just looked at the device – and I have to admit honestly that I absolutely and not understand what exactly the lower scale should display. It is a linear scale of 0-100% – and has absolutely nothing to do with what you want to measure.
Because the values of the standing wave ratio and the power are measured with a logarithmic scale, as one can easily see above.
So I can’t explain the name “F.S.”.
It’d be funny if you write the manufacturer team and ask exactly after that. Funny because they will not know the guarantee themselves 😉 All values to be measured shall be read on the upper scale. Consequently, the lower is completely useless.
I can’t define the abbreviation F.S. (field strength??) – but I guess the statement of this scale says how much percent of the transmission power is reflected, i.e. go back to the radio or its transmission output stage.
At SWR 1:1,1 (i.e. ideal value) 0 – rd5% back-reflected transmission power
At SWR 1:1.5 10% back-reflected transmission power
20% back-reflected transmission power at SWR 2:0.
The higher the SWR, the higher the percentage of reflected transmission power to the final stage of the radio.
Why didn’t you write this directly to the questioner??? He specifically asked for it – not me!
But thanks for the info. Now I can explain the scale. Nevertheless, F.S. does not really fit as a shortcut.
The abbreviation F.S. (field strength??) tells me nothing – but the statement of this scale: This indicates how much percent of the transmission power are reflected, i.e. go back to the radio or its transmission output stage. Two examples

All the foregoing is based on research + personal experience.
If the above hopefully continues to help, please do not “forgot my fee”:)) For example, according to and here “estimate content”.
Unfortunately, it doesn’t help anymore because my question is still open, nevertheless thanks for the effort!
