Hi I have been looking at the picture of the K3 and note that there are adjustable NR, NB and manual notch - but there doesn't seem to be any knob to do the adjustment. VFO 2 ? Likewise there appears to be no control to put the rig into memory mode and to tune the memories - just VFO - M and M-VFO. Some info would be appreciated. 73 Barry VK2BJ
