Any Orion II owner using it with an Elecraft P3? I believe the P3 can be setup to handle the 9 MHz IF of the Orion. That would leave the frequency control. I don't know how the P3 to K3 interface functions (yes, I know it's a serial port), but maybe the frequency of the Orion could be fed to the P3 from N4PY or DXLab Commander. 73, K8AC
