[Boatanchors] Fw: Hammarlund SP600 Model Number Document

[Nick England]

Hammarlund made all the SP-600's -  Northern Radio bought them to modify as 
evidently did TMC and probably others.
Lots of good info on this site - http://www.hammarlund.info/sp600.html

The R-274A/FRR is a Hammarlund SP-600 and so are the R-274B/FRR and 
R-274C/FRR
- The R-274/FRR, however is a Hallicrafters SX-73 and is quite different 
from the SP-600 - no relation other than both can be used in an HF 
communication system.
