Re: [Elecraft] K3S Enable Preamp 2 Without Preamp 1

I have recently been using the 6m ARR GaAsFET Preamp ahead of my K3S. I also find that it has lower noise and perhaps more gain. The proof is that I have been able to work moonrise/moonset EME with it (no elevation on my antenna). John WA1EAZ > On Apr 6, 2018, at 11:16 PM, Jim Brown

Hi John, I operate mostly 6 & 2 meters. On 6m, I have a third preamp between the K3S and the amp. When operating EME, I have to disable Preamp 2 because 3 preamps create too much noise. So, I have disabled Preamp 2. This has allowed me to work EME successfully. I wanted to try an

I am curious what the reason would be for this? I have operated from several countries using my K3S and I am never so fortunate to have a noise floor low enough use preamp 2. Most of the time preamp 1 is also off. John KK9A (PJ4R in 2018 WPX SSB) Stengrevics Jstengrevics wrote: Is there
