Double check the small print on the new reciever. With it being a FP it may be PCM. A PCM reciever would not work with your transmitter. And being it is a real oldie it may not even work wuth the new transmitters. A few years back PCM recievers were upgraded as to the decoding speed. And the old recievers won't work with the new transmitters. Double check the chrystal and be sure it is the same as your trans too. Good luck with it.
