Re: LF: RE: Olivia 8 x 250 / psk31 / MFSK 8 503 CENTER BEACON - RUNNING NOW - 1615 HRS

["Andy Talbot" <andy.g4jnt@googlemail.com>]

Looks like 200Hz and 250Hz to me - looking at three spectrograms, amd
not even properly filling the spaces in between fully.  So occupied
bandwidth is less than spread.
