ESky "Channel Six" CCPM transmitter, which I have and which was sold with Honey Bee 2, is a PPM transmitter (with hard-wired CCPM mix).
You can verify if your TX is PPM or PCM quite eaily by trying if regular PPM receiver will work with your TX. Just take the receiver Xtal and stick it to (any?) single-conversion PPM receiver, then try if it receives your TX signal.

If your TX is indeed PPM (mine has "CCPM_FM" text on the front panel), you can use a serial PIC CCPM interface from www.MileHighWings.com, which will "unmix" the signal and allow you to use your TX with almost any simulator. No other interface, that I'm aware of, does CCPM "unmixing".
