Ding! Ding! Ding! We have a winner.
If you know the level of data modes capabilities in the chasing community, you can guestimate whether there is enough capabilty to make data modes event likely to be a big success or not. I was not particularly thinking about a data modes challenge but more about how successful data modes activations would be in extreme conditions. Hence the addition of the JT modes capabilities.
I can see from the reflector software how many people looked at the poll and I can see how many people visited the reflector site and I can see from the poll how many voted. From those figures I can get a feel for the extent of data modes capabilities extrapolated across the whole SOTA community.
As alluded to already, data modes QSOs can quickly become tedious as you just end up hitting the buttons to send pre-recorded chunks of text about you, your station, your inside leg measurement and hat size etc. Rag chewing is much more rewarding in my opinion (which is what matters!). Where the data modes have an advantage for all of us is in real weak signal working beating CW and SSB by a massive margin.
First thing before inventing a new mousetrap.. find out how much of a market for mousetraps already exists!
