[Elecraft] Problems with KRX3A

[Gareth M5KVK]

I tried that, Richard.
ANT definitely says MAIN but still no signal.

    Gareth,

    Try this.

    - Turn on the sub receiver by pushing sub
    - Push and hold B Set so the display shows b set
    - Be sure the ant shows Main and not AUX.  If it shows AUX push the ANT 
    button to toggle between the two.

    May not be the problem but I've found for some reason my sub receiver is 
    on the Aux antenna.  My rig doesn't have the ant tuner either.
