[Elecraft] Preamps in K3s

[Cady, Fred]

Hi Brian,

You have to go to 17 and 15 meters and go into the CONFIG:PREAMP2 menu and turn it on for those bands.

Cheers,

Fred KE7X

Fred,

Can't find 5.58 anywhere.  After 5.57 comes 5.60 on the ELECRAFT
webpage.  5.6 doesn't access preamps on 15,17M here.

I know there was a pre-release version that had these bands but there
evidently were some small remaining problems to be fixed.

Installed 5.60 on my upgraded K3 (which has PREAMP2 on 10/6M working).
Preamp2 does not show up on 17, 15.  It still does on 12-6M.

73 de Brian/K3KO
