Boy! You sure have that right! What I could never understand about that
company was that most of their receivers I have used were so darned
unstable, especially mechanically, yet their transmitters were for the most
part quite adequately stable.

Like the SX-100 for instance. It looked good, had fairly decent specs, but
was built so lightly that it was terrible, and if you bumped the table while
listening to a station, it wobbled right off that station. This is NOT 
acceptable
for a real communications receiver!

In fact, the most stable Halli receiver I have ever used was the SX-28,
possibly because it was built to Signal Corps specs.

The SX-28 was not built to any spec but their own Ken, it was later chosen 
for military and government service and the AN/GRR-2 version was ruggedized 
but the circuit wasnt changed. The SX-28A was a "cost reduced" version for 
general military service.

The R-274/SX-73 was built for the military and is likely the most stable 
free running HFO that Halli built
