I don't understand why a receiver with a 2:1 frequency coverage in one band 
is any big deal.  As examples from roughly the same period, both the TCS 
and the Hammarlund Super-Pro SP-100 and SP-200 sets cover 2:1 in all or most 
bands.  The AN/APR-1 and AN/APR-4 typically cover about 3:1 in each band.  
The only reason that the US or British/US VHF aviation airborne and ground 
sets only cover roughly 100-156 MC is that that was and with minor 
modifications still is the assigned VHF band for military and civil aviation.  It had 
nothing directly to do with technology.
