Cal,

Your blazing new trails for the JMS.  If this were 1950 maybe you'd have more people 
popping up with experience.  When other members start getting their own 90881's we all 
know who's going to be the new expert.

p-p configuration so I may have to go with the Class B -45 VDC rating. It would be 
nice to hear from someone who has "been there done that" with a live 90881 but I think 
for now, they are "shelf queens". I hope to change that! Cal. N6KYR.
