Dear Gang, I'm running a CE 20A\458 VFO (with CE conversion kit), and driving a Viking Valiant, in turn driving a Hammarlund HXL-One linear amplifier (two 572B's) on all bands. The RX is an HQ-170. The setup has excellent audio and works great. W2EC got the 10-B from me!!! He needs a 458 VFO...........There's one out there somewhere? 73, John, W4NU Atlanta, GA (K4JAG 1959 to 1998)
