       Several of us did exactly this last year (SSTV on 600m).
 The WE2XGR license (505-515kHz) 200W ERP can run practically any data
modes as well as ssb.
By staying above 510kHz we avoided causing QRM to other users of the
band (the others are all below 510).

Results were better than expected, my 100W (transmitter power out) was
copied clearly about 600mi away in Ohio.
I'm sure that if Bob WE2XGR/6 decided to run SSTV with his 200W ERP
you could copy it in the U.K.
