    Have you tried to align it? I have an EKD511 and a R4B would be nice if you would make with a full alignment.

      @@papierecriture I have aligned the preselector only . The EKD needs a sweep generator to align the preselector , usually you do not need to align if the reception is the same with SEL0 and SEL1

      @@IU3EVR Thanks, I was lucky and purchased an EKD511 full aligned but I have a Drake SPR-4 and 4B that need a complete calibration., I find R4'Bs alignment a bit complicated.
