Sorry but I thought it was a mediocre radio. When you open it up you
as yourself "What did they do with the other half of the radio"? You
would be much better off with one of their older pre miniature tube
radios such as the HQ0150,140 or 120. Of the more modern radios the
HQ-110 was not too bad though.

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.

That's not an acronym or abbreviation but a code, intended to hide the
meaning of the message. Pascoela is the Portugese name for Easter
Monday (I think).

http://www.dtc.umn.edu/~reedsj/codebooks.html

Until about 1905 the vast majority of code books supplied
actual dictionary words (or artificial words) as their code
words, such as ``Snatch = Sutter Packing Co., Yuba City,
Cal.'' in the private code of the California Fruit Canners'
Association, or ``Pascoela = Natives have plundered everything
from the wreck,'' in the very popular general-purpose ABC
Code, some supplied number equivalents -- sometimes instead
of, and sometimes in addition to-- the code word equivalents.

But in the first decade of this century code books began
appearing with code words which were meaningless and often
unpronounceable fixed length groups of letters, usually of
five letters. Thus, in a later edition of the ABC Code we have
``ewvgl = Pascoela = Natives have plundered everything from
the wreck'' and so on.

I found a scanned copy of the "Philips Code" on the
web, don't remember where. The Philips Code was a
compilation of the abreviations used by telegraphers and
includes those for commerce and press use. It will show you
the origin of currently used CW abreviations like 73 and 88
adn SK, which is really the number 30 translated from
American morse.
Word codes, usually five letter combinations, were
introduced to reduce cost for transmission and also increase
speed especially via cable. Two widely used ones were the
ABC code and Bentley's Code. I don't know if anyone has
scanned and posted either. Both ABC and Bentley's went
through many editions with additional groups added for new
terms in the same way that dictionaries add new words. Each
group could stand for a whole sentence. I have an ABC code
book in deep storage somewhere.

Perhaps the text on: http://www.qsl.net/ae0q/ ?

The scanned version on a Canadian site doesn't seem to exist any more...

Or the page linked to from Wikipedia: http://www.radions.net/philcode.htm

Same data, but all in one html page.

Pascoela is the Sunday after Easter, or alternately the week after Holy
Week. I think the word is Portuguese; in English we call it St. Thomas'
Sunday.

Could well have been the name of a ship that was plundered by natives at
one point.

I assume you want some positive reinforcement to make you feel
good about owning this receiver It get's a five star rating on this
site:

http://www.dxing.com/rx/hq140.htm

Regarding the set only being single conversion on the lower frequencies,
that is not a problem. The double conversion provides improved
image rejection on the higher frequencies, but single conversion
probably offers stronger signal handling capabilities (less likelihood
of mixer overload.) Enjoy the radio.

And that sort of scheme was fairly common. Change one stage of the IF
into a mixer/oscillator, and get better image rejection on the higher
band (which is where they needed it). It was simpler than moving
to the scheme of a crystal controlled converter ahead of a receiver
that always tuned a fixed range and certainly cheaper. I'm not
quite sure why they didn't just keep the stage always in circuit,
your point about eliminating the extra mixer seems a bit much for
the time (when there was a lot less talk of such things).

The SP-600 did it, the later Heathkit transistor portable shortwave
receiver did it, I seem to recall even the HRO-60 did it (complete
with a microswitch that did the switching when the right coil tray
was plugged in).

I have an HQ-145X that I recapped a few years ago. I've not listened to
it recently but remember that back when it was new I was rather
disappointed by its mediocre stability on CW. But I was very happy with
my HQ-110, which was a good ham receiver for its time.
