Re: [Elecraft] K3S Diversity Setup Question

Thanks all - looks like a combination of the above got things working OK. I
can hear the voices moving around in my head, which would be a bad sign in
any other case, but a good sign for Diversity RX!  ;-)

Don, I'll open the case and have a look around to consider that solution
K2AV came up with - very innovative!

Re: [Elecraft] K3S Diversity Setup Question

2016-08-09 Thread Don Wilhelm 

Bret,

To use two TX capable antennas, you connect the subRX AUX antenna 
connection to the TMP connector on the KAT3, and set the K3 KRX3 menu to 
"ANT=ATU".  The non-transmit antenna will be used by the subRX whenever 
you set the subRX antenna to AUX.


If you want to use a low noise receive antenna, you would connect that 
antenna to the BNC jack, but you need to physically connect the TMP 
cable from that BNC jack to the subRX AUX TMP connector.


A very clever installation was shown to me by Guy K2AV.  Guy has both 
receive antennas and multiple TX antennas that he uses for diversity 
receive, and changing the internal TMP cables is certainly not something 
he wants to do frequently.

Note - K2AV does not have the K144XV installed in his K3.
So Guy put the fan panel for the K144XV on his K3 (Elecraft p/n E100288 
for a K3/100, p/n E100215 for a K3/10) and installed the K144 TMP-BNC 
cable assembly (Elecraft p/n E850378) between the TMP connector on the 
KAT3 and the BNC jack hole in the fan panel.  Of course that TMP-BNC 
cable is too long for the distance, but it can be rolled up and secured 
with a ty-wrap.

The normal subRX BNC to Sub AUX cable is in place.

To operate from a receiving antenna, the antenna is connected normally 
to the BNC jack for the subRX AUX antenna, and the K3 KRX3 menu is set 
to "ANT=BNC" and the subRX antenna is set to AUX.
To operate using the non-transmit antenna, connect a short BNC to BNC 
jumper between the AUX ANT BNC and the added BNC jack in the fan panel, 
then set the K3 KRX3 menu to ANT=ATU and set the subRX antenna to AUX.


If you make that change between the non-transmit antenna and a receiving 
antenna frequently, an antenna switch between the BNC connectors and a 
couple of K3 macros would make the changes easily.


73,
Don W3FPR

all works fine.

For Diversity RX, since the SubRX connects the AUX RX-bnc, I've tried moving
the 43Vert over to the AUX RF IN bnc jack. CONFIG KRX3 is set to Ant=bnc.

I'm not quite sure which buttons to select to get Diversity mode working.
With ANT set to ANT1, I select DIV (long-press SUB) and see SUB on display
between VFOA & VFOB and decimal blinking, but hear only in my left ear.

What might I be missing?

Re: [Elecraft] K3S Diversity Setup Question

Bret,
You have to switch the sub-receiver from the main antenna to the aux
antenna.
To do that go to BSET and press the ANT button. That will show which antenna
the sub is on. It should say MAIN. Press ANT again and it should say AUX.
Press BSET again to return to the VFO A display.

The aftermarket K3s book by KE7X covers the matter ... and many others ...
nicely.  See the Elecraft web page for information.
