K3 with 2m internal transverter

[Jim Miller]

Helping a friend to try to get the most out of his 2m equipped K3
especially for EME.

Is it recommended to use the internal preamp when the internal
transverter is in use? I'm guessing "no" due to to 20db transverter RX
gain.

On page 21 of the P3 Owners Manual it describes the integration of the
K3/P3 wrt attenuator and preamp settings. Does the K3 and P3 similarly
communicate the additional 20db gain of the transverter and reflect
that in a downward push of the P3 noise display?

Thanks

While I use an external transverter with my K3S, I do not suggest using
the K3 internal preamp.  The transverter has adequate gain and also a
good low noise front end.

Hi Jim,

You are right I believe. The effective receiver performance is determined by the transverter. But especially for EME you would like to have a preamp with the best possible noise factor at the antenna to compensate for feedline loss.
