The op at W6SFM was using a 1912 Vibroplex for our QSO which I video'd below. Sorry about the bad conditions - it was a bit early in the day for me to be working the west coast. I'm sure they'll be louder later on 40 meters. Still, it was fun to have a quick chat with both stations using century-old bugs.
As can be seen, I was using my KX2 and KPA500 for about 175 watts out. Is this the oldest key ever to key a KX2? What rigs did it key back in the day?! I bought this bug with the intention being to restore it but it's so much fun to use that I don't want to take it apart any time soon!
Earlier today I worked W0CCA who was using a 1938 Vibroplex DeLuxe and KI4ODO who was using a brand new Vibroplex. Both of them sounded great and were quite easy to copy.
The night is young - on to 40 meters now...
