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

[Sebastian Delmont]

My mistake, from the start, was to not read the entire paragraph carefully,
and focusing on the "one radio" part.

It is the "no receiving while transmitting" that makes the rules
future-proof.

Nothing prevents you from listening on multiple bands if your radio allows,
but definitely no SO2R. Basic SO2V seems to be allowed as long as
transmission interrupts the other VFO (i.e. Flex 6600 without FDX, or with
a single antenna).

If I may suggest a trivial edit of the rules, I'd reorder the sentences so
that "receiving while transmitting..." comes right after "use only one
radio".

Anyways, my question has been fully answered. Sorry for wasting y'all's
time before reading the rules more carefully.
