AN/PYQ-10 SKL: Software Updated

The AN/PYQ-10 simple key loader (SKL), NSNs 5810-01-517-3587 and 5810-01-644-4375, LIN C05002, has newly approved user application software (UAS).

The new approved Army baseline and Army approved version is UAS version 11.0. SKL UAS version 12.0 is now an approved version and authorized for use on all SKLs. No SKL versions earlier than 11.0 are authorized or supported.

Note: You can’t go from UAS version 10.0 directly to UAS version 12.0. You must have firmware 4.10 installed, and install UAS version 11.0 and then version 12.0.
