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).

I have never used my K3S higher than 10m. I imagine that 6m (or 2m like
the original poster is using) is a different animal than HF and the higher
gain preamp would be useful.

I've had the opposite experience. MDS of the original K3 was woefully
poor above 15M,

Hi John,
I operate mostly 6 & 2 meters. On 6m, I have a third preamp between the K3S
and the amp.
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?

Is there some way to enable preamp 2 without enabling preamp 1? Perhaps
electing attenuation on preamp 1?
