Thanks for posting, Bart.
John has been an enthusiastic member of the community for a long time. I first ran across him when he was providing links to DX QSL managers with a well-managed website - back when we did only paper. Also, back then John was running a few tube homebrew transmitter with some kind of receiver. Since then he helped found a (at least) national QRP club, and continue this operating streak. About a decade ago I nominated him for QRP hall of fame given his contributions to the community.
I have QSO'ed with John - his antennas are reasonably effective. He has gone through more rigs than I in his streak, but consistently thrives as a QRP only op.
Yes very nice to find John in QST. We have a wonderful community of ops.
