[ICOM] PR 780 Microphone

[Bill NY9H]

I am not suggesting Bob pays $1.75,,,,  I have no clue what he pays..
I know you can buy great electrets, with broad band audio.. and then you 
have to tailor the freq response like that of a shure 444, a rising high 
end, either mechanically or electronically.\

It looks like the yaesu mic has a 'tunable' chamber, which alters the 
response curve of the mic by  opening / closing access to the back & sides 
of the element.   One of my icom electrets , is "modified"  by covering up 
the ports on the back & sides of the gooseneck mic, causing the low freqs 
to cutoff... leaving an elevated hi freq response.  try it ... while 
listening on another receiver..
At the same time you can make things sound terrible,,,, but it costs 
nothing to mess with it.,.,...

My Elecraft k2 is wired for a Icom mic, so I can use these electrets across 
all my HF radios,,,,
