The HQ-140 and HQ-150 were miniature tube radios. They were pretty much the
same circuit - except that the HQ-145 was dual conversion on the upper band,
which gave it better image rejection.

This is where the subjective part comes in, as I was not impressed with the
HQ-110. It did not have a crystal filter and did not have the ultimate
selectivity of the other receivers. Sure it had a crappy Q multiplier, but
that only gave "nose" selectivity and no "skirt" selectivity. It was more
compact and looked nice. But, I was over at my friend's house when he
brought home a Drake 2B to try next to it. The HQ-110 left the house the
next day and was traded in on the 2B.

Life was simple in those days.

I just reviewed the 1845 Telegraphers Handbook. I suspect that telegraphers
were the first to use acronyms, since they charged by the word and could
increase the amount of coins in their pocket by shortening words. Most of
the acronyms or abbreviations were recognized, but one that caught me by
surprise was "Pascoela = Natives have plundered everything from the wreck".
Not too sure it would be useful today. I am guessing Pascoela is an acronym
from another language.
