Hi

A lot depends on the exact device, but yes, there likely is truth
to this. The coupling on most SWR meters varies with frequency.
The simple / cheap approach for CB would be to ignore the issue
and just calibrate it at one frequency.

Someone once told me that a CB SWR meter would work Okay on higher and lower frequencies but would not give accurate power indications at any frequency other than around CB.

 

Is there any truth to this?
