"mountain out of a molehill here" FCC regulations must be adhered to, just like FAA regulations. Pilots do not get to pick and choose which regulations they are subject to. The "fingers" frequencies are assigned for test purposes and other authorized uses. They are not authorized for aeronautical stations. I wholeheartedly support weirdjim in his efforts to identify and report violators.
While I agree in theory, in practice I am a pragmatist. And in this situation, you/he/we are NEVER going to get everybody to stop using 123.45 as a chat line. It's just not going to happen - it's too ingrained in our minds, and it's too easy to remember, and even if you can't, there's the cute little "fingers" mnemonic to remind you.
While I sympathize, Realistically, if the interference is affecting testing that badly, I'd put some thought into an alternate solution. What that solution is, I have no idea since I'm not involved in any of these particular tests, but it could be a different frequency, a different type of radio (and frequency allocation), another way of signally start and stop, signal flares and smoke signals, whatever. But some kind of new technique might be more effective.
