K3 6m noise figure

[Peter g3smt]

I am trying to calculate my link budget for  50 MHz and was wondering if
anyone has measured the K3 noise figure on this band using the K3 alone
and not with the PR6.  Calculations suggest about 8dB but a measurement
would be most welcome.

I'd be interested in the result as well. I can tell you, though in an extremely
qualitative and anecdotal manner, that the PR6 makes it possible for me to copy signals
that I cannot copy without it -- even in my noisy location.

Yes, the K3 needs a preamp for 6M. I'm using an ARR GasFET preamp in the
RX patch point, and it works fine. I bought it nearly ten years ago for
use in Chicago.

Hi Peter

I measured mine at 13dB about 5 years ago, using a signal generator, so
not particularly accurate.  I use a homebrew preamp on 6m.
