[Elecraft] Heil mic question

[Don Nesbitt]

Jay - the Heil Proset (December, 2004) for the K2 that I have has an
electret (condenser) microphone and therefore requires bias.  It was
furnished with the Heil adapter cable that has a "red" bead on it which,
according to the instructions, "May be marked Kenwood" and came with the
5.6K resistor as well as 8 configuration jumper blocks.  Newer ones may be
different but I doubt it.

Neither the HC4 or HC5 cartridges require bias.  They are not electrets.  I
have used all three with the K2 with great success and am currently using
the Proset (with the electret) on my K3 - also with great success.

Hope that helps.  73 es gud dxing -- Don N4HH  K3 #83

<SNIP> Jay asked:

Is there any difference between the K2 proset and the regular Heil 
proset (with either the HC4 or HC5)?
