[Elecraft] Bias Resistor for the Heil Pro Micro Boomset

[W3FPR - Don Wilhelm]

Carlos,

The proper value for the 'resistor' is infinite ohms - in other words, the
HC5 element is a dynamic type mic and does not need any bias resistor.  It
may also be true that the use of any bias resistor may damage the mic
element - this is just speculation on my part, but I am not willing to try
it on my Heil dynamic elements.

73,
Don W3FPR
