Hi Dex,
 
2 Hz is more than enough. Op-2H consists of dashes of approximately 33 and 66 second duration, so theoretically two signals could be placed as close as 0.03 Hz apart. Taking into acount a few sidelobes on either side, 0.2 Hz spacing should already be well in the clear.

AC4IU is only 260 miles from my location.  I see David shows no decodes
of my signal until after I suspect Bob ceased his transmission.  2 Hz
not enough frequency separation for optimum Opera reception?
