 I happen have a XR-71 kit to work on for someone here . Noise control is suppose to be used conjugation with the Single Control.  They call that the Noise control but  It in fact it's just controls the ON time of the Tx Pulse.  Longer On Times reduce Earth Noise.

What schematic are you working with ?  I have so many I'm lost.  

It sounds like the LM556 is shutting down.   Does it shut down when you go to ether extreme end of the pot ?   Are you using these values ?

     Sounds like it working as they set it up.  Just use a lower value  for R4 or the Pot if you don't want it to reach the shut down level.
