[Hallicrafters] SX-110 vs SX-111

[Glen Zook]

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?
