[ARC5] [Milsurplus] Hacked ARR-7 question

[J Mcvey]

 Wide coverage in only 6 bands. Even though there is a selectivity switch that says "sharp", it suspect it would be difficult to tune in that mode.Interesting radio, though.

 The ANT connector has been replaced with a pilot light.  One can only imagine what other magical "improvements" are waiting inside to delight you.  
   
 True that.  Not to mention the fact that a pilot light is already built into the set - the one behind the frequency dial.  That warm golden light is hard to miss.    
 
 But I have seen worse.  The set, an adaptation of the Hallicrafters SX-28 in an ARINC enclosure, is still my favorite WWII aircraft receiver, passing the BC-348 only because of its IF selectivity options.  With the isolation stage tube socket jumpered with a small capacitor, it has identical specs to the SX-28A (with the exception of the audio output power, since it was only designed to serve headphones.)
 
 Removing the adjustable stop limits for autosweep of a selected frequency range of interest seems to force radio buffs to do something with that bare shaft, thus the large knob.  I never understood it.  You can set the end points to the extreme, and the stops then don't function at all.  I guess it's the irresistible ham "need to fiddle" with things that already work but do no harm if not enabled.
