Sounds to me like multiple streams is the nature of the beast in digi
contesting. Those interested in it should embrace it.

You don’t need multiple rigs...or multiple copies of the software to do
it....one copy of the software will do it, if set for dxpedition mode, I think
the most I saw was 5 at one time...3 at a time is usually 3 different TX audio
streams, when you go more than 3 you’ll get 2 stations on the same audio freq,
one getting a RR73 and one getting a signal report....
