Thanks.
Sure. If you use a separate transceiver for telemetry (like a radio modem) of course it will conflict with another system on the same frequency (or potentially will, depending on how it uses the spectrum). In the case of FrSky or Spektrum, the same transceiver that is receiving from your signals is also replying with with telemetry data. There should be no reduction in range at all. The question would be though, does interspersing command and control packets with telemetry data impact latency? Because full duplex communication over a single shared medium will always reduce the total bandwidth.
