On my last ship (CFAV "Quest"/CZDO) there were five H.F. xmitters
installed in mid-life refit by the Navy, all capable of 1kW each with
MCW mode which I found strange because the int'l regs stated that MCW
could only be used on 500kHz, the reason being that auto-alarms reacted
better to a MCW signal than CW.
Coming back to CZDO, I never called anyone in MCW but I could have,
especially since I could couple all 5 TXs together to produce a 5kW
signal! I'm pretty sure I would have been heard on the first call....
However I once modified the old Oceanspan tx on H.F. to use MCW on one
of my ships in the Far East and called Sydney/VIS on one of the HF bands
only to be told pretty sharply to stop using MCW immediately.....which,
of course, I did!😬 Got a quick response though...
