Re: Power output on 20 meters.


That meter is also full spectrum, so measuring all frequencies not just 20M.

Hi Mike

The 9.2 RF Power meter is not bad, but not fantastically accurate. But it is important to realise, this measurement is an RF detector, it will only display a correct power reading for a sinewave into a 50-ohm load. The waveform at L3 is very much NOT a sinewave. The 5.2W measurement is meaningless...

Hi All

Results on 20M using 9.2 RF test feature......

Output from L1 with 50 ohm load on output = 2.2 watts approx
Input to L3 with 50 ohm load on output = 5.2 watts approx

Input voltage on load prior to protection diode = 12.13 volts

The caps are the correct values, so I am going to change the toroids one by one.
