Hi Jack;

Mine uses a BNC connector on the sig gen end. I made 3 cables, one with a
PL-259 on the other end for radios using a SO-239, and one with alligator
clips on the other end for screw terminals, and one with a RCA phono plug
for those radios with a female RCA jack (Heathkit, Collins, etc). All
parts are available at Radio Shack. IIRC, you need a 10 dB, 50 ohm,
in-line attenuator for the other scale on the output meter. Good luck and
Merry Christmas.
