Chuck,
I don't have one, but I have the manual and have studied it and the
balun. I would test it by placing the 200 ohms across the antenna
connections, and connect the 259 to the 50 ohm connection. It is a voltage
balun, but should have a decent SWR from 3.5 to 29 MHZ when so
connected. If it still doesn't read 1.2:1 or less, check your connections
of all the wires.

The testing procedure calls for you to connect a pair of 100 ohm resistors
in series between the two 200 ohm terminals, then test the SWR with a jumper
connected to the input shield and to three different locations on the
resistors. The instructions state that the SWR should be low when the
jumper is connected between the input shield and the junction between the
two resistors. Then it should show poor SWR when the jumper is connected
between the input shield and either one of the BALUN output terminals. My
tests showed no difference between any of the three connections. I have
double and triple checked my soldering connections on the BL1. It is not a
complicated module to assemble.
Has anyone else tested the BL1 with a 259?
Is the BALUN safe to use or should I just stay away from testing equipment
without adult supervision?
