I can't find 2.57 on the beta site (just 2.46).

I'm afraid it's your browser John. I have Firefox set to clear it's buffers, cookies, etc. when it closes and it's there on the Elecraft site now at: ftp://ftp.elecraft.com/K3/firmware/beta/ 73 Dave, G4AON I can't find 2.57 on the beta site (just 2.46).

[Elecraft] K3 Beta firmware rev. 2.57 -- SSB PWR control, SPLIT in diversity mode, etc.
K3 beta-test firmware revision 2.57 (with DSP rev 1.94) is now available. This is a major release.
