Really needing help I am an amputee and use the Futaba FP-8SSAP single stick transmitter on 72mhz and is PCM. I am having heaps of issues around PCM receivers that work and don't work. When I use a Futaba 8 channel PCM 1024 it will not work. I change the crystal to the Futaba 72 PCM it works fine. It appears to me that there is a difference from 72mhz PCM and 72mhz PCM 1024. No matter what crystal Dual or Single I am unable to get the receiver with PCM 1024 to work with my transmitter yet it works fine with PCM receivers. Would appreciate some help
