The math above was intended to help as we kick around various things regarding possible rule changes and it certainly doesn’t address the politics or problems we hobbyists have with trying to be compliant with FM rules.
Carl, you have pointed out, and I agree, that a positive change would be some way that the user can tell if they are in compliance. We really caught a break with 15.219 in that with a $4 (sometimes free) DVM from Harbour Freight and a little electronics knowledge and a tape measure we can determine compliance.
Now, as you mentioned, we find that certification is not as reliable as we had hoped. The calculations I demonstrated do nothing to solve this dilemma.
Even if the FCC agrees to an increase in field strength such as the Canadian rules we would still be faced with the same problem of knowing our field strength. Perhaps we need to find another way to specify compliance and get it written into the rules, something which is within the capability of modestly equipped hobbyists to implement.
