Your call minded me that I had a nice QSO once with KJ2U. Will let anyone curious look that one up…
The nice thing about having even a simple card is that you can build up a pretty neat collection, even if you only send them selectively. I also felt bad when someone would mail me a card and stamped envelope before I had one to return, so I hand sketched a few responses on notecards. I always enjoy seeing hand sketched cards in the old timers’ collections.
It is cool, but I feel the shame of never having cards or going on the air any more.
I dabbled with SOTA (Summits On The Air) a few years ago.
I bought some bits to make a rig interface for FT8, but they never got soldered up. I was going to put up an EFHW at home. Yet another hobby waiting for me to have free time!
KJ8T but I've never made my own QSL card...
