Just a quick mod to the CN-901 SWR and Power meter. This mod allows the SWR needle to work when the meter is set to PEP measurement mode. Not very practical but it looks nice!
A very simple mod that just involves bridging 2 points on the PCB with a small jumper…
The 2 points shown with the tweezers.
Jumper installed. You can see how easy it is!
Just put it back together and watch that SWR needle swing!
