[Elecraft] Microphone and BFO questions

[Geoffrey Mackenzie-Kennedy]

Rolf,

My K2/100 is #3255 and I use the Heil Proset Plus (normal version) without
any modifications to the KSB2.  Get full spec PEP on all bands speaking in a
normal voice which the XYL says is quiet. Sorry I cannot comment on the
other mics.
