Ralph, Thanks for your informative reply. You're right, there were several manufacturers that made these units (Midland, Pace, Numark, etc.). I did try to hook it up, but the SWR was 1.3:1 (almost the same as I got with a dummy load), which I thought was too good to be true, but maybe it was due to the low wattage being used (4 watts). I'll get some proper cables built and go from there. Thanks again.
