RH: What is the ouput power of the Crane FM T either out of the box or tweaked up? Do you or does anyone else know?
Rich: I don’t, anyway.
RH: So you are saying that the FCC will base its case on a theoretical, laboratory environment and not on actual field measured conditions?
Rich: No, they will measure it. What I’m saying is that you can’t expect cable and connector loss to reduce the power of a tx able to supply as little as 1 mW of output power enough to produce a legal field when radiated by a matched, 1/2-wave dipole.
RH: There are places inside my house, 3 meters from the transmitter where you can not pick up its signal. Nada, niente. That tells me that there is a lot of attenuation in the signal’s path to those spots. (There are also other spots where there is a good signal quite a way’s out.)
Rich: Receiver performance depends in part on the radiation patterns of the transmit and receive antennas, obstruction losses, and signal reflections from other conductors and surfaces along the radio path. Together they can produce the results you report.
