HI Jerry, I'm assuming you have the Turnigy 9X that has the antenna routed through the radio and up through the top. Sadly there is no known PPM-compatible receiver for these modules that I am aware of. Years ago the Hobby King HK-TR6A receiver provided PPM on the battery output, it was an undocumented feature but it did work. For whatever reason this feature was removed sometime around 2011 (so a very long time ago now). Several people myself included have asked Hobby King over the years if they would restore that feature, but it's never happened.

To my knowledge, and as it says in the Wiki, the only way to use the 9X radio with the TCB is to use an aftermarket module.

Although I have not tried them there are indeed PWM->PPM converters, here is one someone mentioned to me the other day in the RC Tank Warfare thread: Hobby King Signal Converter

It's untested but should work. It will require lots of wires though.
