You have two options. We would prefer that you purchase the accompanying CX-AUTO which provides eight coaxial outputs. However, if you prefer to simply add a second coaxial output and don't need the balanced output, we recommend the following procedure:
- Unsolder the balun lead at the antenna relay.
- Remove one of the balanced output connector "Bolts" and associated nylon insulating hardware.
- Insert an SO-239 connector in the vacated balanced output connector.
- Solder a #14 wire from the center-pin of the SO-239 connector to the relay contact which previously went to the balun.
If you follow these steps, this modification can readily be "undone" and no added holes, etc. will be necessary. The firmware will associate the "new" coaxial output with the "Balanced" memory settings, etc., and will be selected whenever "balanced" or "bal" is shown in the AT-AUTO display.
