Birds should chirp, not metal detectors

Only drawback with frequency shift is that it locks you into Tx 2 (cannot change it when frequecy shifted off nominal freq) so unless you have a need for a specific frequecy, best to just wholesale change it to one of the other 3 available. As a side note, 4khz cannot be shifted and is always locked at Tx 2, if I recall correctly.

a frequency shift affects performance too and should only be used if all else fails ,just change the frequency.

Right, I believe that is bècause the coil is tuned for the centers of the 4 nominal operating frequencies, not the shifted frequencies. That is also why they probably also limit TX power so as to not put wasted transmit energy into the coil in offset frequecies which just creates heat.

As always great information fellows! Who would have thought, shifting the frequencies would have a negative impact on performance
