This is something that does not appear to exist. I would prefer an option to have the P3 track VFO B on the K3 instead of VFO A. There is a good use for this in SO2V (single operator, two VFO) operating, where your VFO A neighborhood is (usually) boring but VFO B can be interesting. 73 and thanks for listening, Carl WS7L K3 #486
