Never had a problem John getting full rated PEP output from K2/100 #3255 using the HC-4 and HC-5 elements in the Heil ProSet Plus headset without an external preamp, but I don't use the K2/100's VOX. If I used VOX a little more audio gain would be required in the VOX circuit, but additional

Thanks Gian. At this QTH, which is in the first hop zone of 40m BC signals on their way to N.America, the receiver's IMD3DR needs to be 110 db approx at 2 kHz spacing if used for weak signal SSB DXing above 7130 kHz. Of course the LO must be very quiet. The big problem I have here is BC

In 1998 when living in Luxembourg I bought some 50mm diameter knobs from RS Components in the UK. Their stock number was 170-632. They also had the same type of knob, which RS Components described as a Handwheel, with diameters of 40mm and 60mm. The rim is knurled and there is a revolving
