Thanks Dennis!
I figured that this must have been the case. I have trouble imagining what
being a radio officer on a merchant ship must have been like in, say, the
70's. I've never seen any of the equipment, and I've read little about it.
From what I've heard, it certainly wasn't a cushy or "romantic" job; most
had additional duties beyond simply manning the radio. A few were not
particularly good operators and had terrible CW skills -- it was simply a
job. I've read about conditions around WWII in the QCWA Journal, and many
were nothing short of horrific. Most of what I hear about is CW, but I know
there had to be a fair bit of 'phone used, too, and I assume that most of
that was AM for quite a while.
It's hard to dig up much of the history of this after WWII, either about
day-to-day operations or equipment used. Does anyone have a good source or
reference?
