We’ll use Morse and put the key down to transmit a signal. Also set the transmitter to a low-power.
What is FS on SWR meter?
Under the actual SWR reading is the percentage of reflected power – i.e. 25% of your power being reflected back is just in the red. Below this is the FS reading – you don’t have to worry about this – it stands for field strength and is not a facility used when setting up a standard legal CB.
Can you leave a SWR meter in line?
You could leave the SWR meter connected in-line, but you have to have a way to secure it so it’s not bouncing around and it’s out of the way. Really, if you can access the connections on the back of your CB, it’s easy enough to connect the meter to calibrate your antenna and then remove it.
How do I test a SWR meter?
To run a test, simply connect your radio’s coaxial and antenna cables to the indicated ports on the meter. When you set the meter for calibration and activate the radio transmitter, you’ll see a number indicating the strength of the signal being broadcasted. SWR is typically only tested on mobile or base installations.
How do I adjust the SWR on my antenna?
Turn the radio to channel 1. Key the microphone (depress the button and hold it). Turn the knob on the SWR meter labeled “SET” or “ADJUST” until the needle reaches the setting position at the end of its range. While still keying the microphone, flip the switch on the SWR meter to the “REF” or “SWR” position.
How do I calibrate my SWR power meter?
Turn the SWR calibration knob fully counter-clockwise. Key the microphone and, while continuing to depress the talk button, adjust the calibration knob so that the needle touches the “SET” mark on the meter. When the needle reaches the “SET” mark, flip the switch to “FWD”
How do I lower my SWR?
One technique to reduce the reflected signal from the input or output of any device is to place an attenuator before or after the device. The attenuator reduces the reflected signal two times the value of the attenuation, while the transmitted signal receives the nominal attenuation value.
Do you need a SWR meter?
At power levels that low, you probably don’t need an SWR meter permanently installed. You will find it useful to have an SWR meter or antenna analyzer available when building the antenna, though, to ensure it is properly operating on your chosen frequencies.
Can I use a CB SWR meter for ham radio?
Many hams have re-purposed CB SWR meters but there are so many variations that some caution and testing is warranted. Many CB meters were not designed to handle the higher power levels of amateur transceivers. A 100 watt transmitter could cause component failures within the meter.
How do you tune an antenna to a SWR meter?
