Narrative:

While on an ATP check ride; climbing out in cavu conditions at approximately 800 feet per min and 138 KIAS; we had a near miss with an opposite direction B-737 on descent into the airport. We were tuned into both center frequency and local traffic frequency and heard no position reports from the 737. There were no traffic alerts and no transponder target depicted. When I saw the 737 I disconnected the autopilot and initiated an immediate descent. I believe the main problem was that the jet did not make any position reports. Also; lack of ads-B coverage both in the area and on the other aircraft prevented me from being alerted to their position. Corrective action would be to increase the number of transponder transmitters through the ads-B system so aircraft equipped with ads-B type traffic avoidance systems will be alerted to transponder only traffic.
