Again, I know this has been covered before, but I can't find it.
What is the typical noise floor in terms of uv/m for both urban and rural environments?
I know that it takes a certain field strength n*x to induce a signal strength of x into the input of a receiver. I recall that n=2.5 to 3 for the FM band. Would that factor remain the same for the AM broadcast band at around 1.7Mhz?
Those two sets of facts, along with the graph produced by Rich in the other thread should give anyone a good idea of what kind of range to expect for a good Part 15 AM installation with a monopole antenna.
