[Hallicrafters] Best RX?

[WA1KBQ at aol.com]

Good post Tom,
 
The McLaughlin side band selection scheme you mentioned, I wonder if this  
is Jim McLaughlin who worked with James Lamb in the mid-thirties to develop 
the  XE1G Dual Diversity receiver which Hallicrafters made soon afterwards 
as the  DD-1 with chief engineer Karl Miles and Jim McLaughlin consulting?

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?
