[Elecraft] KRX3

[Roy Morris]

I have just installed the KRX3 and set the filters for the main receiver.  The auxiliary KSYN3 has been calibrated.  CONFIG: VFO IND displays UNAVAIL.  Am I supposed to be able to set the filters on the SUB?  Is the SUB supposed to be operational letting me hear two frequencies simultaneously at this time, or is this coming in future firmware?  I presently get nothing out of SUB even when I set B-SET to antenna 1.  Advancing SUB RF and AF gain does not bring the receiver to life.  Do I have a problem?  Roy Morris  W4WFB
