Subject: TS-440S MODIFICATION TO USE ANTENNA TUNER FOR XT AND RX.-
Remove case from rig. Remove (4) screws that holds antenna tuner in place.
Next slide antenna tuner out to get to the coax connections. Remove the input
coax attached to antenna tuner from FO connector on filter unit (X51-340-00).
Remove coax from out connector on antenna tuner and install in FO CONNECTOR ON
FILTER UNIT. Unplug and remove switch unit (X41-1610-00 N-14) from rig.
Remove short wire from antenna connector to PC BOARD. Cut coax on the input
connector of antenna tuner in half and connect cut the end to switch unit PC
BOARD where short antenna wire was removed and shield to ground. Solder other
half of coax to antenna connector and shield to ground, and plug other end
into output connector of antenna tuner. You still have control of antenna
tuner with auto and thru switch.
It works very well. Maybe someone can use this idea.
