no, i do not mean frequency. i don't know exactly what shift is, but some radios have different shifts from each other. for example, one cannot use a futaba transmitter with a JR receiver since they have opposite shifts.
Don’t worry about the shift - I know that Futaba receivers will work with the F-14.
To me when my servos "glitch" it usually means that the batteries need to be charged but there can be many other reasons also. When you get the glitches – is anything else running? (Pumps, props, etc….)
What is the model number of the receiver are you using?
Ok, this may be where the problem is the F-14 is not a PCM transmitter. I am not familiar with the PCM, as I have never used one. So if someone else can speak up here it would be appreciated. In the mean time I’ll see what I can find out.
Hi All: PCM is short for Pulse Code Modulation and refers to the type of signal that a transmitter produces. Shift is a frequency offset. In FM the signal is "wide" rather than "tall" like AM. AM is Amplitude Modulation where the transmitted power in varied up and down. FM uses a constant power and changes the frequency, typically 5 KHz of center frequency. Since we are not working with music or sound, we don't need such a large change in frequency. Thus, one maunfacturer can choose to use the area which is the primary frequency +5 KHz and another the primary frequency -5 KHz. Thus the term shift. Shift+ or Shift-. Another term is "high side" and "low side".
If I haven't put you all to sleep by now, or given you a brain cramp, on a receiver there is a switch for PPM/PCM. This must match the transmitter type if the receiver is universal.
PCM is specific to each brand, so you can only use a Futaba PCM Tx with Futaba PCM Rx, Multiplex PCM Tx with Multiplex PCM Rx and so on. Many years ago, Multiplex led the way with PCM, being the first model aircraft radio to have PCM, before Futaba/JR had it. As usual, Multiplex has moved on and developed PPM with the full programmable failsafe features of PCM, so they have stopped making PCM Rx, and their latest Tx the Royal Evo does not have PCM. If you buy their older Tx such as the Profis they have PCM but you would need to find PCM Rx second hand. To get the failsafe features in PPM you have to buy a Multiplex IPD Rx, which is cheaper than buying a PCM Rx and it can be used with absolutely any brand of shift compatible PPM Tx still with its fully programmable failsafe, unlike a PCM Rx.
