The problem may be known. Just talked to Gary at TT service about my strange behaving Pegasus: only works 160 to 30; but 20 and above only noise rcvd and xmit. He says the rig switches to a different VCO for 20 and on up. Most probable problem is that VCO has ceased operating. So into the box and back to Sevierville today. 73, Jim KH7M
