[Milsurplus] [RCA] SRR-13 Article

[antqradio at sbcglobal.net]

HueI haven't seen a response to your query.  Perhaps both are rare enough that no one has the operating experience to compare them?
To start the ball rolling specification wise, the R-808 is single conversion below 8 mc, has a 2nd crystal controlled above 8 mc.  Second IF is 455 kc, not sure if there are selectable IF bandpass filters, will have to check the manual to be sure.
SRR-13 is double conversion on all bands with three L/C pass band filters at the beginning of the 200 kc second IF.  First IF is 1600 kc.  The SRR-13A has the two narrow 200 kc filters replaced by RCA designed mechanical filters but the broad filter remains L/C.  Filter bandwidths are approximately, 1, 3 and 8 kc centered on 200 kc.  There is also an audio filter that has a pass band of 825 to 1175 cycles which is switched in for the A1 sharp passband position.
