I think I would contact Ramsey and see what the resistor selection
limitations are, unless you have a schematic and can determine it from the
Sure enough, if you set it for 10 watts you are going to, some day, put 50
or 100 watts through it in error and I'm assuming if you kill the remote
switching it defaults to receive and therefore doesn't switch the preamp out
resulting in a trip up the tower to fix 2 things.
If you set it for 100 watts, you will someday want to run less and again it
won't key. Same trip up the tower.
Hard wiring, as has been suggested, is your safest choice. As the switch has
the relay in it, maybe Ramsey can tell you where to tap in to directly
switch the sensor.
Nice choice of rig though ;-)
