And if John doesn't have a 1N270, I have many left from my RTTY TU building
days that I will make available.

Yes, that would be CR5. It is a Germanium diode (1N270), which is
difficult to find these days. A Schottky such as 1N5711 should work ok if
it is bad.
You should have ~ 1 - 1.5V p-p at the INJ jack, and ~ 3.5V p-p at the
collector of the Band Oscillator.

Thank you Garrey
Strange strange 1.6V pp I have that!! I will have to remeasure that; but
looks like ther is another issue !!! I've read something about a diode
on the PTO Xtal mixer between plate and screen. BTW I had 620pF and
changed to 390pF.
Looks like if I fixed the PTO and after remounting something other fails.
Oh murphy!!
