Confirm receiption of a 2-tone FSK signal on 82k8 (approx)
which just fits into 200 Hz of IF BW.
According to well informed ITU persons this might be

(1) GYW on 82k750 assigned freq. located at

05W20/36N09 (Gibraltar), using F1B, occupying 190 Hz of
BW and feeding 40 kW into the antenna.

(2) GYB on 82k750 assigned freq. located at
00W10/51N30 (London), using F1B, occupying 200 Hz of
BW and feeding 40 kW into the antenna.

The frequency is 82.75 khz and because of its strength here in the UK is
most likely GYB.
Transmission type CW and RTTY and idles at times on carrier.
G3KEV

Perhaps one of our LF_friends in UK may try to
DF to resolve the source of this signal.

Closest, notified frequency below/above the observed
one at 82k7 is:
82k4 and 83k1 respectively.

Hope this helps.
