I am using DSD+ Fastlane edition with two RTL-SDR dongles. One is set for control of a Cap+ system, and the second a voice.
As of now, my control is not decoding (not active control channel), but I am getting an annoying burst of static. I don't know where this signal is coming from, or why I am hearing it as the voice control (to my knowledge) hasn't been tuned to a frequency to be picking this up?
Does the voice control VFO stay on the last frequency it was last tuned to whether or not fmp24-vc is controlling it anymore? I do know that when I was decoding the system when the control channel was active (I think I'm missing a frequency as none of the known are broadcasting it) I was hearing the burst of data (similar to what I am hearing now) despite not sending audio from my CC VFO to the speakers.
Actually, as I type this, the CC has returned to the frequency (451.5750). I see the pulsing on the scope. Sometimes the data burst sound accompanies the pulsing, whether associated to that control channel, or it's the same interfering burst I hear when the CC isn't active.
I'm wondering if it isn't some interference. The data burst seems to match another Cap+ control channel in the area of 451.4875.
So in a nut shell, why am I getting this data bursting when there is no voice being transmitted? If it's interference, is there a way I can eliminate it?
