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
