[Milsurplus] HRO

[Hubert Miller]

Maybe it's kinda like the jeep: nothing really earthshattering about the design, no particular magic, but the configuration idea just
works well. Germany did not copy the receiver in great numbers. I think this was only early-war, but I'm not positive about that.
It was only one of a great number of different receivers built by them. The Japanese copy seems to have been not built in large 
numbers either, judging on how rarely you see them here, which I admit, not a very scientific sampling. But even the huge Japan
Special Receiver 92 with all its numerous coils, is seen here more often than their "HRO copy". The Australian AMR-100 and AMR-101
were copies provided to the U.S. military, kind of a reverse lend-lease, but there was also a copy of the SP-200.  Australian firm
Kingsley produced two "copies" for Australian use. Somewhere I read mention that there was a N.Z. version also but I have never
seen any photo. 
I think the BC-348 variants were almost as much in number and possibly the BC-348 "era of use" extended farther than for the HRO.

Occurred to me to do a quick, rough count:
HRO  U.S. versions for military, through -5
U.K.   R-109 ?
German KST 
Japan Chi-Ichi
Japan   "3/4 size" "paratroops equipment" ( ? )  "Chi-Ichigo  ( ? )
A.W.A. ( manufacturer )  AMR-100, AMR-101
Kingsley  KCR-7 or is it KCR-11 
National Radio ( Seattle )  ( labeled )  S-20
R.A.S.  U.S. Navy
D.D.R.  ( East German ) AQS ( I think that's the model name ) 
oh yeah - motorized U.S. Navy model for bandsweeping; article in AWA Journal some years back.

>The HRO was copied by the Japanese and German forces during WW2 and Australia thought that it also was worth the trouble.  Henry Rogers also hints that other allies copied the design but didn't mention who.  Oh, then there was East Germany after the war.

Can any other receiver of  this vintage claim as much flattery?  There must be some desirable attributes to the National design to have so many imitators.
