My last post might have been a bit confusing, making one think that the wire amount changed with the frequency adjustment when you turn the black core in/out.
The tuning core won't do anything for straight dc voltage, the coil would always be the same resistance with or without the little black core. It only works on RF signals
49Mhz coils are pre-wound with 7 turns of wire and 27Mhz are 12 turn coils. Tuning the core in/out only changes the frequency it will resonate at, maybe down to 45mhz or up to 53mhz at the most, but the coil still has the same turns of wire it started with.
