[Elecraft] Questio when using a Heil Proset

[Don Wilhelm]

Ross,

If the bias turns out to be your problem, know that you can run the Heil 
Proset from the rear panel jacks and the MH2 from the Front Panel mic 
jack.  The bias settings for the two mic inputs can be different.  Just 
decide which mic you want to use and select that one in the menu - it is 
quick and easy.
