RE: Spectra Module
Fact is every Tx/Module combination, same brand or not, will vary in both width and strength. We had an incident this weekend where a guy with an 8U on dedicated module (channel 52) that had just come back from being tuned was crossing over onto 53 and caused a plane to crash into the pit area. The guy on 53 immediately asked if someone had turned on 53 and there was no response. When we retrieved what was left of the plane, we plugged the battery back in and the servos were obviously being manipulated by another radio. Fortunately, someone had a signal scanner and we were able to see when the channel went clean to figure out what had happened. Moral of the story is that even FCC approved, dedicated module systems can be a crap shoot. Without a full time spectrum analyzer (too expensive and impracticle), we all take a chance every time we go up or turn on a radio. Note: I'm getting one of those scanners, $140 = Cheap insurance!
