What IS a QSO?

Earlier I had an interesting email from a friend in the village about what was a QSO. To him, unless there was a 2-way voice contact it was not really a QSO. He did not like FT8 contacts because these could be done PC-PC without a human even being present. These days, using systems like Echolink, one can talk to handheld stations on the other side of the world.

His email got me thinking. I use FT8 mainly because I use QRP and my voice is poor these days. I can still use voice modes, but it is hard work both for me and those at the other end!

Having said that, I like being able to assess conditions with WSPR and FT8. These systems work with weak signals and are far better aids to seeing if a path is open than SSB or CW can ever be. For a start, using the internet databases, there are lots of people monitoring and they are all monitoring the same small chunks of spectrum. Last night, for example, there were 17 FT8 QSOs on 160m in just 2kHz of spectrum. Being weak signal modes, brief openings are caught. On 2m FT8 I can be consistently copied at great range with 2.5W to a simple omni antenna. On 2m QRP SSB I struggle to work over 200km. With FT8 double or more distance is possible with QRP irrespective of conditions.

To me, Echolink QSOs are not "real" QSOs as most of the way the internet is the bearer.

I guess all we can conclude is a QSO is different for different people. Old timers (like me?) still like DX contacts by "real" radio, whereas these days this is arguably unimportant. To me, the challenge is propagation. For some it is the joy of just talking to people.
