[Elecraft] Orion added to Elecraft rig RX comparison page

Tue Dec 2 12:37:00 2003

I notice that the K2 phase noise at 4 KHz offset the LO is -124 dBc. The =
BDR at 5 kHz is 135 dB. Shouldn't the phase noise dominate and determine =
the BDR at this offset? I am making the assumption (perhaps incorrectly) =
that if the phase noise at 5 kHz offset is -124 dBc then a signal at =
+124 dB above the desired received signal will mix to produce noise of 0 =
dB (referenced to the received signal). Note that I am assuming the =
phase noise at 5 kHz offset is the same as at 4 kHz offset.=20

Hi Toby,

The Orion numbers Ten-Tec quotes on their web site are what they were =
claiming=20
from their lab tests on the Orion, versus the final ARRL review numbers. =
They=20
will probably change their posted numbers now that the ARRL review is =
out,=20
since this is the standard for comparison.

We try to only post ARRL tested numbers on our comparison page to =
eliminate=20
any question of bias. We certainly do not filter our numbers :-)
