[GreenKeys] CRT Question

[WA5CAB--- via GreenKeys]

Two caveats. The converter has to be a filter type and the CRT vertical and 
horizontal channels have to be capable of operating at the filter 
frequencies. The CRT display from an FM or Discriminator type converter will produce 
two horizontal lines. And the AC (RF or Audio) output of the filter channels 
is what is fed to the CRT.
