Well lets see the schematic shows 300v ahead of the coil and 215v after. So that leaves 85v across the coil probably less and a rough figure of 100MA current (it's probably more) comes out to about 8.5watts then double that. I would say 20watts would work. You could start with a 10watt resistor and see how fast it gets hot. Be sure to watch the voltages and adjust accordingly.
Personally I would make up some adaptors for a 100ft extetension cord and hook up the speaker. Thats if there are only three wires. I don't think the radio will care much about the long wires. If you have a baby monitor you could use that to listen the speaker from the other location.
Desperate times call for desperate measures
Good luck
