Hello Ray and readers.
Correct Ray. I am an ex ocean going radio officer. Yes, I used very
often SSB reduced carrier when requested by some Coastal Stations in
order their receivers could be locked on my carrier, which had to stay
permanently on while carrying out radiotelephone traffic. The pressel
on the handset activated the modulation.
