Human Factors
After take off turned left cross wind; after passing 1;000 AGL engaged autopilot. TAS system detected a target on a crossing course. Disconnected autopilot; when TAS turned black and gave audible warning put aircraft in climbing turn to avoid target. TAS indicated a '00' solid diamond passing underneath us; made numerous attempts to [contact] incoming pilot; 'No Joy'. Contacted FBO and told them of situation and to ask pilot why he wasn't communicating. Pilot stated to FBO that he was on frequency 122.95; this is our old CTAF frequency. One year ago frequency was changed.
PC-12 pilot reported NMAC with an inbound aircraft at CNM when the inbound was apparently using an outdated CTAF frequency.
