[Elecraft] Rx-In/Out used for exteranl SDR Device?

[Bob KD7YZ]

Hello Elecraft List

I recently got my K3 back from Elecraft. They'd upgraded it to K3s.

I used to be able to run a cable from the Rx in out area on the right-upper-rear as I face it.

That gave me antenna without the threat of RF into my SDRPlay.

I tried Rx In and Out then pressing RX on teh front, but the S-Meter drops 5 S-Units.
Yeah, signal does go to thje SDR device, but at a huge loss to the regular operations.

What am I not seeing here ?
