You didn't say what model of comm radio or strobe, and distance of
strobe components and HV wiring from the comm antenna.
As a reference, a Whelen single strobe (monster joules) does not break
manually-set hair-trigger squelch on either of two handhelds I have,
beyond a distance of 2", with a short (5") unshielded run from pwr
supply to head. Any HV run longer than that should be shielded,
grounded only one end, usually at pwr supply, but flipping it might
work better says one mfr.
Re the comm itself, many have elaborate circuitry in the squelch
circuit to break only when it senses actual RF carrier, not junk like
this. Some comms may be more crude. If you have manual squelch,
there should be no need to set it to the hair-trigger threshold for
usual communications, which may crudely solve the problem.
There are no devices I know of to cure this, as a simple filter can't
distinguish real carrier from the umpteenth harmonic of junk.
