With a bit of certainty, I am led to believe that the VFO in the Project X rig is inoperative. The Malocchio is in effect! Back at You!
Getting the VFO assembly removed from the rig for repair is daunting, but getting the unit back into the rig is an even bigger, almost insurmountable task. The old axiom, when in doubt look to technology for a solution. Enter the Arduino with the Si5351 as the saving heroes.
For some this has Italian roots found in the word "scandalous". While it would be cool to keep it original, it is an Analog VFO that has failed! I have upgraded many commercial radios and long ago faced that decision.
The change over while not in the original plan does upgrade Project X to a rig with finer gradations on the frequency readout while also providing extreme frequency stability over the original which only held a 100 Hz drift for only 10 minutes.
Since Project X was intended primarily as a SSB rig, the original covered only the phone portions of the bands. We now can use FT-8 with the Digital Electronics.
We also have many choices for the display including LCD, OLED, Color TFT and even the JF3HZB display.

No, this is not "THE" display, but a very nice hardware display!
Yesterday I whipped up an Arduino LO using an LCD and tested that on one of the bands. It worked surprisingly well and that experiment is tilting and coloring my decision on a R&R action... you know the old Rip Out and Replace parlor trick.
Them that know can make it go.
