The 301 I am working on needed this badly. The clarifier knob was a full mark to the left in order for the receive audio to be the same with the clarifier on/off.

The instructions are straightforward, the only thing that surprised me was that when moving the adjustment pot, it doesn't change the frequency of the clarifier to the radio frequency, it shifts the radio frequency to the clarifier setting - weird, but it works.

I also noticed that after this adjustment, it seemed like the linearity of the frequency readout was improved as I tuned across the 80 m band from 3.5 - 4.0 Mhz. I can't 100% confirm this, but now when I tune and check every 25 KHz against the marker, it just needs a very minor tweak across the entire range. I don't think it was like this previous. I would be curious if anyone else doing this adjustment has seen anything similar.
