[Hallicrafters] SX-110 vs SX-111

[Duane Fischer, W8DBF]

Additionally: 	
	
The SX-111 without the product detector has 13 tubes, the model with the product
detector has fourteen tubes.	
	
The selectivity on the SX-111 is greater than on the SX-110. As it should be,
after all, it is for Ham band use, not general coverage.	
	
I use a SX-110 that has been electrically refurbished by a great Tech, KO6BB,
and it is an excellent receiver for short-wave listening and general purpose
Amateur Radio copy. It is quite sensitive, reasonably selective and a stable
performer. 	
	
One observation: I have noticed on many Hallicrafters receivers, and this is
probably true of other brands too, that poor solder connections under the
chassis are not uncommon. I have found marked improvements in receiver
sensitivity when said connections were identified and fixed. My SX-110 is such a
case. It worked fine, or so I thought. But after the connection was resoldered,
there was a dramatic difference.	
	
This is my own personal opinion: general coverage is the SX-110 and Ham is the
SX-111. If you are going to Ham, get the one meant for the job.

The SX-111 is a ham band only receiver and the SX-110
is general coverage.

Also, there is a definite difference between the
SX-111 and the SX-111 Mark I.  The SX-111 does not
have a product detector (uses the old diode detector
"game" to receive SSB).  The Mark I does have a
product detector.

The SX-111 is more stable than the SX-110 since it
covers much less spectrum.  In addition, the SX-111
series was sold as the "companion" to the HT-37.  The
prices generally are about the same for the receivers.

Every SX-111 that I have seen has the variable trimmer
capacitors in the oscillator soldered shut!  You have
to heat them with a soldering iron if the calibration
is off to be able to adjust them during an alignment. 
However, they do seem to "pull onto" calibration
fairly easily.

Of course, the amateur band calibration is much closer
on the SX-111 series than the SX-110.  Also, the
SX-111 is usually more sensitive on the higher bands
and you don't have the image problems caused by the
single conversion of the SX-110 versus the double
conversion of the SX-111.

I am familiar with the SX-110 but not the SX-111. Is
there a noticeable performance difference between the two?
