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! Randy, K5ZD > -----Original Message----- > From:
