I have two of the CN-801HP meters and one CN-801HP3 meter. I have performed the modification to enable the power reflect needle to operate in the PEP mode. They work great.
I just recently purchased the new CN-901HP meter (801HP's no longer available).
The meter has changed somewhat. All push buttons for operation and the PC board has also changed. I have searched extensively for a modification to enable the SWR needle in PEP mode. None available.
So, I spent an afternoon taking my new meter apart and tracing the circuit board.
I have located the points for the SWR/PEP modification. Just add a short jumper very carefully, just as in the 801HP meters.
I will post the photos showing the mod.
I do not take responsibility if this modification does not work for you, or if you make a mistake.
