JR R10DS Overview JR R10DS 10-Channel Dual-Conversion Synthesized Receiver.
Most people tend to attribute the exceptional performance of the R2000 to its most visible feature: the frequency synthesizer. While it can be said that the synthesizer does help keep the receiver locked-in on frequency extremely well, the synthesizer alone is not responsible for such a quantum leap in performance. So what is responsible?
In talking with JR’s engineers, for technical reasons they elected to change the 10.7 MHz stage IC of the R2000 to a completely new unit. The payoff of this new IC is that it offers a far superior signal-to-noise ratio than the old unit. In the two examples above, both models had a form of model-generated noise or blocking, which the R2000 filtered out. JR attributes this principally to the updated IC.
That said, receiver design is part art, part science. Clearly, the R2000 is an exceptional blend of high sensitivity and high selectivity to give your model superb protection against interference – in today’s complex RF environment. JR R10DS Key Features - 10-channel dual conversion receiver

What is PCM and PPM? |
| The PCM receiver is a digital receiver that
uses normal FM Frequency, but the signal is an encoded digital signal in which
the PCM receiver interprets it as commands. Since the signal is digital, if
there are any interference or the signal is poor, the PCM receiver can be
programmed to go into a fail-safe mode. In this mode, the servos will move to a
pre-programmed position until the signal comes back.
PPM receivers are the "standard" type of receiver for most
radios. Glitches in signal are immediately noticed by erratic movements of the
servos.
JR's computerised radios give you the best of both worlds with
each transmitter software switchable between PPM FM and PCM for superior
interference rejection.
