The boundary wire for my Husqvarna 330x automover is 1200m long, so the signal is too weak for the mower to properly follow the boundary in and out.
Husqvarna does not have a signal booster for the 300 series, only the200 series, neither do they have a secondary signal generator.
I want to boost the signal with an active amplifier, so a schematic would be helpful.
This signal would feed a loop going around some areas inside the main loop, which should not be mowed.
I've measured the signal with my dusty 'scope, and the signal seems to be a digital signal, either 2v or 0v into a 20 ohm loop.
It is 50hz with some code appended to the trailing edge.
I could try to simply use an audio amplifier, but I guess it would be better if I could replicate the base station.
So a schematic would be helpful.
