Strobe / Radio Interferrance

[William Mills <combined.merchants@virgin.net>]

At the low end of the radio frequency range; 118.000 to about 121.000, I hear 
loud
clicks in time with my anti-collision strobe, which, if tuned for any length
of time, is a bit like the Chinese water torture.  I should be most grateful
if someone could let me know if this can be suppressed and if so, suggest what
type and size of device I should fit and where to fit it.
Regards to all,
William Mills
