Hi, Bill- Unless I am mistaken, there is supposedly a schematic available for the MFJ-931 in Devoldere's "Antenna and Techniques for Low-Band DXing".
I have the 931 and use if with my EFW, both in the shack as well as while portable. It works well for me, plus one cannot have too many gadgets containing wiggly meters hanging around- hi. If you cannot get a copy of the schematic, let me know off list and I'll open up my unit and trace something out for you. As I recall, it is a simple variable L/C network whose output passes through a toroidal transformer that provides current info to the front panel meter. You could of course dispense with the meter and use a lil light bulb to help tune for maximum current. 73, Mychael/AA3WF K2#1025 _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
