Interesting recording to say the least!  David, what frequency were you tuned into on the radio?  I'm intending on beginning where Metascience Foundation left off:  29.575 MHz, amplitude modulation.  I know the Mark IV block diagram shows FM, but the actual device was AM as stated in the Technical Manual.  Which really makes sense.  Modulating the frequency would be difficult, and take much more equipment to do; plus, since we don't know how a Spirit actually modulates the RF during impingement, FM would just get in the way.

Anyway, what was that frequency again?
