[Elecraft] [K3] Sub-receiver with one antenna jack

[Bill K9YEQ]

Ron,

I know so many on 75 meters SSB think they need to run receivers of any
brand with the Pre-amps on with no attenuation.  Probably they want to say
how strong everyone is?  I run generally with Pre off and attenuator on
160-40 meters SSB.

73,

And I'd expect NO penalty for sharing the same antenna except, perhaps, on 6
meters. The K3's noise figure is already quite low. Indeed, watching the
e-mails posted here, it seems that a lot of K3 owners fail to turn on the
attenuator on the lower bands and some even run the pre-amp which degrades
the receiver performance even though it makes the bands sound "louder".

The subrec includes an aux antenna jack (BNC) so you will still have
possibility of two antennas.  There is also the REC antenna on the KX3Va
module (if installed).

I have a fairly bare-bones K3, ie no provision for a 2nd antenna and no ATU
installed.

If I install the sub-rx, what is the penalty in terms of MDS due to the fact
that both the main and sub rx will share the same antenna?

Thanks/73,
