[Elecraft] K3s & CBLP3Y to P3 - no signal does follow VFO

[Gary Smith]

Hi,

I just connected the CBLP3Y cable to the P3 & K3s. The frequency 
shows on the P3 & the SVGA monitor but I see no signals on the 
waterfall. It was working fine with the K3 when I disconnected it and 
it is now not working. 

I do have RS232 configured to USB and I have made sure the jack & 
plug have mated with a click on the K3.

Ideas of what I need to do to get the waterfall working?

Thanks & 73,

Gary
