Narrative:

VFR departure from tki runway 17 VFR. Once we turned to the east we never heard another radio call from the tower to our aircraft. We then continued our climb VFR and had a TCAS TA. There was less than 1000 foot separation with an md-80 uncomfortably close enough for the TCAS call. We continued our climb and leveled off for another md-80 that went 1000ft above us in the opposite direction; then a 737 went 1000 feet below us opposite direction. We finally made contact with fort worth center as the controller was calling our aircraft as traffic to each aircraft inside of byp on the northeast arrival into the dallas/fort worth area. With a closure rate of 10 miles per minute with opposite direction traffic; high rates of vertical movement and the volume of aircraft on the arrival into the area this seems like a very dangerous operation. The TCAS was set to a non-standard 10 mile and above setting; not the 5 mile normal setting called for in our fom.
