What did you find with a lrl

[Dubulumach]

Alonso PD is very very hard tuning lrl, because you are playing with 2 Tx and 2 Rx at same time. Need fully perfect balance to not saturate other one and vice-versa. Also success depend of ferrite rod type.

Also, i have known a man who had throwed away complete Alonso PD after very hard and long tuning, in the big river, when he had been cornered to the blind alley. No more Alonso PD for him.
