I have noticed that the RF gain on the Sub RX will often drop way down. I recall it happens when the SUB RX is first engaged. But twisting the knob a bit brings it right back up. This happened at FD when I was using the Sub Rx to S&P listening between CQs. Ideas? -- Buck, k4ia DXCC Honor Roll 333 8B DXCC K3# 101 KX3 #715
