Re: [Elecraft] Preamps in K3s

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,

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.

Thanks Frank.

[Elecraft] Preamps in K3s

2017-06-10 Thread Jim Miller 
I'm confused a bit about how the Preamps in my K3s work.

When Preamp2 is engaged are the preamps stacked for a total of 30db
additional gain or does the Preamp2 engagement disengage Preamp1 for a
total of 20dB?

Or perhaps they are both engaged for a total of 20db with Pre2 boosting
over Pre1 by 10db?
