Is there a procedure for reducing the VOX sensitivity in the K2? I have found nothing in the Manual or in the Menu menu. I am using a Heil Proset. The VOX triggers when I let a pen drop on the desk . . . I believe I am using the recommended SSB settings - SSB-A at 2 and SSB-C at 3-1. Any advice? Tnx, Ted, KN1CBR
