Gents, Aren't we talking about low-band FM?   Refresh my memory, what harmonic and IF is involved here?

I've been working on a BC-659 WWII FM set and have the receiver on "life support" power. I picked a couple of crystals out of the front row of the CS-137 crystal case and one was marked FREQ-KC 5700 CHANNEL  271 with  271  marked on the top and plugged it into the "A" position on the set and then "A" was selected on the set.   Then  I thought I could hear strange signals that were very weak and it seemed odd  as a antenna was not connected  to the set. I then attached my trusty Operations Center long wire  and signals starting coming in and I then proceeded to peak the receiver stage trimmers.  However the stations  could not be identified and it appears they were just a mass of stations all transmitting at the same time. No voice or CW identifiers could be made out and the remarks made by the station operators did not make any sense-it sounded like the English language but hard to identify the remarks by the operators.  Mystery  FM signals on 5700 Kc?

Here is a link to the audio and a photo of the 5700  CHANNEL crystal is attached.
