Too bad the cables in the first video are not terminated.

The cables, used as antennas, will affect the resonant frequency behaviour of the RLC circuit in the tuner. This is basic radio “one on one”. For an antenna out of spec, the outcome would be that the markings on the tuning dial would no longer correspond with the actual tuning frequencies of the circuit.

I wouldn’t be surprised if he had turned the tuning dial so a resulting new resonant (tuning) frequency for each of the cable-tuner combo’s would match the frequency of some received carrier signal, all cables would score the same.

I’m staying out of the cable debate...but this experiment with the tuner is just flawed for what he is trying to prove.

BTW...just out of curiosity...did he use the AM or the FM circuit to conduct this test ?
