[Hallicrafters] Best RX?

[Tom Rousseau]

The SX-111 may look similar to a SX-110, but that's where the similarity
ends.

As already pointed out, the SX-110 comes from the S-20R, S-40, S-85, SX-99
lineage.  It is single conversion with a 455 KC IF.

The SX-111 is architecturally very similar to the SX-101, being primarily a
cost reduced version.  Both are double conversion with a 1650 KC first IF,
50 KC second IF, same McLaughlin sideband selection scheme and a similar
tube line up.  The SX-111 saved money primarily by eliminating a lot of
expensive mechanical material (cast escutcheon, heavy duty chassis and
cabinet, robust tuning capacitor, geared tuning, fancy
selected-band-backlighting, etc).  Compare the block diagrams.

The SX-101 takes its general architecture from the SX-100, primarily being
converted to ham band only, optimized for ham performance, and beefed up
mechanically.  But comparing the block diagram, they are very similar.  The
SX-100 evolved from the SX-96 which evolved from the S-76 (the first
Hallicrafters to employ their popular 50 KC last IF scheme for selectivity).

The SX-115 is pretty much a new architecture, except it borrowed the 50 KC
IF from the SX-101, et al, and the VFO from the HT-32/37.  The SX-117 is
quite similar to the SX-115 architecturally, though cost reduced in many
ways.  Nice little radio, though, for its intended purpose.

My favorite of this lot is the SX-115, followed by the SX-101, for ham band
only.  The SX-100 certainly has its warts, but for a general coverage
receiver it is very nicely balanced, giving good overall performance in a
compact package at a good price.

The SX-111 is a hamband SX-110 which is a SX-99 and on back to the SX-9.

You already have my SX-101 opinion but you havent said what you intend to 
use any of them for?
