I've noticed that behaviour as well. As long as I keep the volume of my voice up, it seems ok, but if I speak normally it sometimes seems to cut out on lows. > After much experimenting, including the building of a second KSB2, I > ended up building the single transistor amplifier, the circuit diagram > of which is available on the Elecraft website.

Maybe now I'll build it sooner! :-) > By the way, I now have two microphones with HC5 elements; one amplified, > and the other 'stock'.

I'm free afternoons, evenings, and weekends. Hope you don't mind me shouting at you... :-) -- 73, Brian VE7NGR _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
