The amp, Thetis and N1MM+ are all on the same PC. Unmanaged Ethernet T switch used to tie pieces of hardware together.
Played around with this yesterday and for some reason:
1). The frequency on the N1MM+ spectrum did not match that on the Panadapter of Thetis. The N1MM+ frequency was always off, but it did change when I tuned to another frequency on Thetis, remaining off compared to the frequency displayed on Thetis.
2). The number of TCI clients kept rising from the normal 1 (I use TCI with my RF2K-S amplifier and it works very well). However, I also have a USB connection between the amp and Thetis. TCI is for use of VNC (Virtual Network Control) that enables porting the amp GUI and operating the amp via a mouse on the external display.
Realizing that I haven't included screen-shots, I will do that a little later, not to waste anyone's time (which I may have already done

Happy Easter/Holiday!
