k3 sub receiver ant selsction

[iz0fyl]

Hi folks
just a question.
I' don'nt understand the selection scheme of the sub rx.
In the figures of the manual seems that is possible in the aux rreceive using ant1 on main ant ant 2 on sub.
the question is: isit possibile to reiceive on main rx the anti1 signal and anthe sub rx the antenna 2 signal?
I tried on my k3 but I hear the ant1 in both the receivers
thanks

  Luca,

Yes, it is possible to hear the subRX on the opposite antenna that the
main is listening to.

You must have a TMP cable connected between the KAT3 and the antenna
input of the subRX - that cable is not installed on factory-built K3s,
but the extra TMP cable is shipped with the K3.

The antenna that is NOT connected to the Main RX will be heard when the
AUX ANT is selected for the SubRX.

If the two antennas are not well separated, you may hear the COR in the
sub being activated during transmit (clicking noise during transmit).

See Figure 4 on page 43 of the manual.

73,
Don W3FPR

Hi Luca,
Here is a picture showing what you want to do.
http://www.ke7x.com/home/guide-to-the-k3/main-and-sub-rx-antenna-switchi
ng
It shows the Main Rx connected to ANT1 and the Sub Rx connected to ANT2.
You must have Config:KRX3 Ant=ATU. Then turn Sub On (tap SUB) and then
either RX ANT or Hold BSET and then tap ANT.
When you have this configuration you can switch the antennas back and
forth by tapping ANT.

thanks
now it's quite clear.
so if I select ant=nbc the sub ant in main path is the same ant of the main rx (one ant for both rxs)? rigth?
