Golden Mask 18kHz coils inductance and resistance values

[m23585]

I have three coils for Golden Mask 18kHz models (GM1+, GM4, 4Pro). I measured inductance and resistance but I don't know which values are for TX and RX. Anyway, it may be useful for someone, so there you go:



Could anyone explain why there are values in four pairs of pins?

Well it looks like 1 to 4 is your RX coil and 5 to 2 or 3 is your TX coil. Seems funny to short 2 AND 3...
