Fern,
My posting on Mics got some strange responses mate. I use an old Turner+2
(34 years old) and it gets perfect audio reports all the time.
I was following the posts on Mics so I thought maybe a "Super Mic" was a way
for Elecraft to increase sales.

It is true that the AGC pertains to the radio and not the
band, but the optimal AGC threshold setting does vary by
band. On 80m, for example, I set the AGC threshold on my

is very low, I set it at 0.5uV. The Orion, incidentally, has

Look no further as I've found that the Shure 444D is the ideal base
