Hi Everyone

I am hoping for some help with is Radio as regards PCM Settings. Whenever I select PCM mode to take advantage of using all 9 Channels it Glitches very Badly and the Servos Twitch Uncontrollably and it keeps losing it's bind with Receiver. the Seller doesn't have a clkue and has Suggested Forums like this to resolve Problem.

Any Ideas anyone?

There aren't really any settings for PCM, except in relation to failsafe, and that doesn't seem to be your issue. I happen to have the 2007 manual issued when the radio was released and don't see anything helpful.

I would look to things not directly connected with PCM but affecting the radio link, such as the transmitter and receiver crystals.

It's going to be difficult to do anything if the solution is not a simple thing like a crystal not seated properly, as support for MHz modules and receivers had pretty much ceased by 2010 (that's the year they removed the long antenna from the transmitter). In reality, the radio had gone over to 2.4gHz well before that.

It's probably time to convert it to 2.4. If you use an FrSky XJT module and Er9x firmware, you can get up to 16 channels.

Hi Mate

Thanks for the reply. It already has an FS-RM002 Module and FS-R9B Receiver so that side is done. I take your Point about Firmware and Higher Spec Module, but it bothers me a little that when I switch from PPM to PCM the Glitching starts! So I think it is a Synthesised 2.4GHZ rather than FHSS like Futaba.
