David, Wayne said: "It's actually more like -144 dBm (500-Hz bandwidth)." I assume that this refers to a K144XV installed in a K3.
This equates to a noise figure of 3db. To achieve a lower noise figure, the gain used in the K144XV would have to be greater, which would further reduce the overall dynamic range (IMDDR3) of the K3 assembly on 2m. 73, Geoff GM4ESD David Pratt wrote on Friday, January 08, 2010 at 9:34 AM > In a recent message, AD6XY <m.j.wil...@rl.ac.uk> wrote ... >>I can not see any reference to noise figure in the brochure.
