They're probably just using FL studio as a VST host. I think the combine voice effect is fairly simple; bandpass of something like 300hz to 3khz (telephone range, maybe walkie talkies are smaller but couldn't find details), amplify for hard-clip distortion, add in some white noise in addition. Maybe also pitch-shift downwards before the bandpass. Voicemeeter potato can do the actual routing from your real mic through reaper and plugins and back into VRC.

I'll see what I can do once Im out of the wage-cage-from-home.
