Why not just make it a 40 KHz tuned xformer?

Somehow, my brain converted the 60 KHz WWVB frequency, to the 40 KHz
frequency of the vehicle detection system I'm working on. The
frequencies mentioned should be 60 KHz and as usual, my arithmetic
sucks.

target. At 40 KHz, that's a -3dB bandwidth of 200 Hz, which is rather
wide for a 1Hz wide WWVB signal.

At 60 KHz, that's a -3dB bandwidth of 600 Hz, which is rather
wide for a 1Hz wide WWVB signal.
