R-274D/URR ?
I just got this unit at the ABQ swap and started looking for a a manual with
Google and found that unit is differnt from the ones I've found pictured. It has 3 Collins mechanical filters. At the top upper left it has a Squelch control and next to it is a Noise Silencer control. The mode swtich is labeled AM and SSB/CW. The lettering looks factory done. The filters have been added on a sub chassis and I'm not sure it is a factory mod or homebrew but it has been nicely done. The S meter was made by Texas Instruments. It has some problems including lots of nosie, hetrodynes, etc.. I've only seen one of these in the past and can recall which version it was, they must be scarce? Anyone have any info? -- 73 Hank WD5JFR |

Appears to be the Mil version of the SX-73 at any rate, also similar to the SP600. Seems to be Hallicrafters? dxAce Michigan USA |

The Hallicrafters were designated R-274/URR, R-274D/URR and SX-73. The Hammarlund SP-600's that had the R-274 designation were listed as R-274A/URR, R-274B/URR and R-274C/URR. The full list can be seen at: http://www.hammarlund.info/sp600.html How about a photo of what you got? Les |

Sorry, it says FRR, not URR!

Yea that would have been a rare one allright. It's either a SP-600 or a SX-73. The collins R-390, 388s etc used the URR designation and other radios but I've never heard of a R-274 under that. I'm just going on memory so I could be wrong. -- 73 and good DXing. Brian ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ A lot of radios and 100' of rusty wire!
