You know, I pleased how much I learned from this thread, and so clearly expressed. I'm no engineer, and I struggle a bit to learn this stuff. My circle of friends includes not one RF engineer, if you can believe it. :-). This thread is Eham at its best.

RFRY said "Most receivers state their input sensitivities in units of ┬ÁV needed at their antenna input terminals.  That is a measure of voltage, not power (such as dBmW)."

OK, sensitivity can also be specified as dBm(50 ohms) which satisifies your uV requirement. 

There's more than one way to skin a cat.

One that used to be seen in telephone work was dBm0, representing 1mW in 600 ohms. Not to be confused with the occasional dBmO, for dBm output!
