[Elecraft] K3 Mini

[W4IEN]

I am running my K3 Mini to my K3S via wireless.  I am running into a strange issue.  Every time I go into CW mode I am getting a ringing noise. I can get rid of the noise by changing the RF Gain.  The thing I am wondering about is I am not hearing any CW signals on 20m, 40m or 80m.  I am just wondering if there is something I have set wrong.  I am also wondering if the RF Gain is set properly.  I know this question is a little vague but I am in the last stages of getting this remote setup working well.   Any suggestions would be greatly appreciated.  Thanks in advance.
