Tim in Bovey conducted his professional field strength test on a C.Crane FM2 sent new from the manufacturer, but we cannot assume that every unit they send out is set to the same RF level.
My FM2 also came from the manufacturer, but it was an “orphan,” which is their word for “returned for resale” by a previous owner. We do not know if the first owner changed the internal setting, and judging from a slightly upturned edge of the sticker on the rear, they may have. Did C.Crane retest it for compliance? We don’t know.
To reach a general conclusion about these transmitters Tim would need to order a few more and test each of them, and he’d need to check mine to see if it matches the “new” (non-orphaned) units.
Because of the lofty and arcane (secret,mysterious) nature of 15.239, we have more unknown unknowns than known knowns.
Rich believes adding an odometer is our responsibility and not that of the FCC.
