I've measured the following noise figures:
10.5 - 12.0 dB main RX, PREAMP on
17.0 - 21.0 dB main RX, PREAMP off
11.3 - 17.9 dB sub RX
This thread is an example of the fact that many amateurs
make no distinction between the noise figure (which is important)
and the audible noise level (which is irrelevant).

Were you able to run NF on many freqs? Is there any frequency dependence
on your numbers, or is the Orion NF fairly constant 1.8 to 30 MHz?
Tnx very useful info!
