Furthermore, percentage readings are only one possibility.
For comparison, dBµV oder dBm values would be best IMHO, however,
due to different sensitivity of the frontends, there would still be
a difference when trying to get a "percentage" because one frontend
locks at -90dBm, the other needs -85 to get the same BER, just as
an example.

...and if at all, should be fixed in a way that is suitable for more
professional applications, too. :)
