Since it's probably just an SDR internally, I'm sure someone with a bit of RF know-how could put a transmit amp between the antenna and the device.

  These are much simpler. Usually just a 555 setup as a triangle wave generator connected to a series of voltage controlled oscillator chips with a small amp, one per antenna.

    Oh wow, that's delightfully retro. I love 555 timers.
