Topband: fixing beverage

[Herbert Schoenbohm]

Jorge,

 1. Measure the wire resistance in respect to ground and it should show
    a resistance a little bit higher than your termination value. This
    will check for breaks in the wire,
 2. Put a temporary termination on the end of the coax (any convenient
    value) and measure it at the shack end.
 3. Check both sides of the beverage box with an ohm meter and you
    should see only a few ohms on both sides.
 4. Put a 450 ohm resistor across the Beverage side of the transformer
    and check from the shack with a  MFJ-259 for SWR.
 5. If you don't have a MFJ 259 or equivalent try running 1 watt RF out
    the cable and check the VSWR at the shack. (Most boxes with take a
    couple of watts for a few seonds assuming you have a 2 watt resistor
    across the Beverage side terminals.
 6. Pull the wire out of the weeds.☺
