[Milsurplus] RPS

[Ray Fantini]

I was going to set up a display with a Russian RPS receiver at MRCA this weekend, did several Russian radios last year with a R-311, R-107 and the like but this year wanted to do something different. was going to set up a RPS with power supply and speaker and have some forms their with a picture of the radio and let people try to determine what function each knob is by operating it. If you read Russian you may be excluded!, then who ever submits the form with the most correct answers will win something, don't know what yet will more then likely be some Russian pins or the like. 
I needed some background information on the RPS, like when it was in production and what type aircraft it was used in.
