[Milsurplus] [RCA] SRR-13 Article

[Michael Bittner]

I have For Sale two new-old-stock mechanical filters for these receivers.  These are from a former surplus outlet associated with the Long Beach, CA Naval Shipyard.  I have tested both with sig. gen. and scope and they are in perfect electrical and cosmetic condition.  One is by RCA, the other by Magnavox.  Photos available at:

Asking $15.00 each plus $6.80 shipping via small flat rate box.  If you want both, both can be shipped in one small frb.  Personal check OK.  If interested, please reply off-list.
Mike, W6MAB

  I 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.
