Honestly I don't know. I have never done a "before and after" comparison. Don't know why, just haven't. I have done the mod a lot by request and never had anyone come back and say it didn't work. Conversely I've never had anyone say it did either.
I realize not the answer you were wanting but the best I can do. I do have a couple in here so I could do a comparison. Now my curiosity is up.
Do not bother. I just wanted to see if you had noticed. I just don't like hacking radios. Granted this is not a transmit or receive mod.
