[Elecraft] K3, PR6 bypass question

[ejkkjh at gmail.com]

I can not get the PR6 to bypass?
I have been using my K3 and PR6 for awhile but I have not tried connecting a receive antenna to the PR6 until recently when Wayne said to use the K3 receive antenna port for 630 meter receive.  I pulled the jumper P2  in the PR6.  I have the 15 pin connector that comes with the PR6 connected to one side of the Y 15 pin ACC connector from the K3, other side of the Y goes to the KPA500, KAT500.  And I have the DIGOUT1 set on for 6 meters only, all other bands it is off. If I pull the 3 pin power, ctrl connector from the PR6 it goes to bypass and receive ant works fine.  Read through the manuals, did not see what I am missing?
Any help would be appreciated.  Thank you  73
