Larry and others-
  yes, I did check for plate and screen voltage at  1st osc.  it is there  when @ 7mc, and switches off when going to 8mc.  
   When you connect a wire ant.  to this,  you get a lot of increase in background noise, when on 8mc.  No change  when on 7mc.  No static when connecting antenna at 7mc.
   No reception at all below 8mc.  I can hear a calibration signal [100kc],  but it is  way low  on 7mc.  
   I would like to build an extender  cable  for the RF section,  but I need the female harness connector.  Anyone  have one  they  can part with?  
   I suspect an input  short  only on the lower bands?  73s Russ.  thanks  guys
