[CQ-Contest] Why the 10 min rule anyway?

If you have more than one signal present on one band, the FCC considers at one of them to be spurious and therefore illegal. That's a bigger deal than a contest rule.

Now how many of you have heard Multi-singles in SS Phone giving an exchange, while another voice in the background was clearlly CQ? There's no microsecond switching going on there, that's an actual M/2. This happened a couple of years ago with a club station in my area. The operators in this case were unaware that they were doing anything wrong and have since learned the error of their ways, but this example does illustrate how easy it is for a "M/S" to actually operate like a M/2....if there isn't a 10 minute rule.

We all like to talk about things being in the "spirit of the rule." However, the 'spirit' is often open to interpretation by each participant! At the top tier multi-multi and multi-single efforts, there are often multiple stations on one band. This allows a second station to make QSOs while the main station continues to run. Most people who do this a very careful to prevent multiple transmitters being on the same band at the same time. However, it does start to push the credibility of being multi "single". How would the multi-single rule be written to prevent this? Think about it before you answer. Its not as easy as it seems!
