...As in giving comms? Mechanically?
Inter-faction comms such as F-CI, F-GOC, CI-GOC, giving any faction's comms to D-Class or allowing them to be naturally obtainable? If so, no. I think that would be too abusable. I can understand the RP purpose and I think there some interesting cases where comms could be given to D-Class - CI having the ability to give D-Class comms would be fire, honestly - It'd make sense, may potentially give more use to CI's internal comms (I know that on UK, they're somewhat criminally underused as a byproduct of preferring TS), but also would give justification to that weird thing that happens sometimes during D-Block raids where after killing a bunch of CI, suddenly a bunch of new, competent D-Class appear, who immediately move in concert with the CI participants of the ongoing CI raid. Real strange, that one

With other circumstances potentially being things like D-Class work programs, GOC stuff, etc. etc.
But otherwise, while there is obvious purpose, I think that both the difficulty of implementation, the sheer abusability of it and the degree of unbalance it would cause, would render that idea something that would not be accepted under any circumstances. I believe there've been discussions about it before that reached this conclusion.
But that's assuming that's what you were asking for, which isn't immediately clear. Another interpretation of radio could be the radio SWEPs that were recently removed from the server for good reason. That one's kind of an easy no. Another would be the radios that chefs can spawn... We don't really need more sources of those. But I'm fairly confident that the comms interpretation is correct as what you suggest evokes the thought of a 'police scanner' and when I think about that in context with what you're suggesting, that's the clearest concept that comes forth.
It's difficult to understand, but I understand that English is difficult for a lot of people, especially for anyone who is ESL - I myself would not even know where to begin when it would come to trying to communicate an idea to a foreign community, in a language that I don't understand, so IMO it's certainly impressive that you were able to convey what you were able to. I hope I was able to interpret this correctly, but unless you were meaning something else, which again, is entirely possible, I don't think this is feasible.
interesting idea for CI, not so much for d class - maybe could be a part of the upcoming "CI/F warfunds update" dropping in 2028 to access each others comms for very expensive and for a limited time perhaps.
I do like this idea, though.
