For the last few nights on 1020 KHz where I normally hear KDKA out of
Pittsbugh I've been hearing a non english voice (French?) and the
"tick-tock" of what sounds like a time signal.

I'm almost certain you are hearing a "harmonic" of the Canadian time
station, CHU. I don't recall it's exact frequency off the top of my
head, but it's roughly close to 3 times 1020. Odd stuff happens in
radio, sometimes, most especially in shortwave radio.

It's 3330.0

Yes, CHU is on 3330, but no, 1020 is not a harmonic of 3330, or any
frequency greater than 510 kHz.

What you hear on 1020 is Radio Reloj (spanish for "Clock Radio") out of
Cuba.
They broadcast news items with the ticking in the background and a time
announcement at the top of each minute, as well as a morse code "RR".
