[Milsurplus] ARN-6 Question

[Tom Brent]

In the late 1960's, the Canadian Armed Forces had a bunch of ARN-6 radio compass receivers modified by removing the 100 - 200 KHz band and replacing it with 2.0 - 3.5 MHz coverage. The modified set was assigned R-717/ARN-44 nomenclature. Searching on the 'net has revealed that the US Coast Guard operated C-131A "Samaritan" aircraft (acquired from USAF stock at Davis-Monthan) beginning in 1976 that were also equipped with the ARN-44. Have you ever seen one of these sets? Was there a radio originally manufactured as the ARN-44 or were the USCG ones also modified versions of the common ARN-6?

Thanks for your help!!
