msf5000 secure firmware upgrade

[ddayfarms]

I am wanting to upgrade my old uhf msf5000 repeater with a secure board. I need to upgrade the secure firmware to version to 4.28 would anyone out there have a bin file for the secure board?
Thank you in advance

I believe asking for this goes against the site rules as they stand right now. What are you running secure on? It's not compatible with current narrowband requirements...

MSF secure boards are cheap and plentiful on the 'bay. I had good luck finding complete control shelves out of surplus 800 MHz stations that had the boards installed, with matching firmware revisions.
