Wrong info Doug. Your ZJ "thing" has a MAR-1 in it according to ur
number.
Owners have found at least 4 different MAR MMIC's so far. NOT
interchangable without changing bias resistor either. 

As discussed here at length a month or so ago, the choice of device PLUS
the matching xfmr in the ZJ box makes it an all around poor choice for
Beverages. Nice and cute toy but no good for real world use. 
Suggest you check the Archives for comments by users, W8JI, myself, etc.
