[CQ-Contest] What is "one radio"?

[Randy Thompson]

I am going to refer to the CQ WW rules, but I think they are same for WW RTTY and WPX.

Rules that cover every future variant of technology are hard to write.  It was hoped the simplicity of "The entrant will use only one radio..."  would be sufficient.  Especially when the rule also includes "Receiving while transmitting is prohibited."

The intent was to go back to a boy and his radio.  As radios get more receiving capabilities, perhaps a new FAQ should be created to make it more clear what is allowed or not.  E.g., use of a second VFO (so called SO2V) is ok, but looking at a panadapter of 5 bands at once may not be.

Hint: Winning Classic is more about selecting the right operating times than trying to get an advantage from a second receiver.

Many contests include a "Classic" overlay that is defined as, among other things, the requirement to "use only one radio".

How does this affect the use of radios with multiple reception units?

Does this rule prevent SO2R operation when you use a single radio, with a single transmitter but able to listen to more than two signals at once?

Or was this rule meant to prevent this kind of operation, but got obsolete and was never revisited?
