[Milsurplus] Needed: R-28 Schematic

[Brian McQueen]

Hello to the group,

Does anyone have a schematic for the R-28 that they could possibly scan and send me as a pdf?  I found one on the mil list site, but alas, it is illegible (at least to my near-sighted eyeballs).  Also, what are the IF frequencies and formula for crystal freq?  Any help would be greatly appreciated.

Tnx fer the bandwidth,
