But even though the K3 is cycling TX/RX very fast the 8410 is not banging the vacuum relay to death trying to follow 30 wpm dits. 30 wpm QSK*does* significantly shorten relay time to failure. Contesting, I've worn some out in less than a year.
I own three very nice vintage Ten Tec amps that use vacuum relays. All of them came to me used, and I've replaced those relays in each amp at least once. After a few rounds of that, I stopped running QSK with those amps. :) I'd like to hear from others having experience with vacuum relays and QSK at contesting speeds. I mostly work between 28 and 32 WPM. The original equipment relays were Jennings, and I've mostly used Gigavac as replacements. I haven't had to replace one since giving up on QSK about 8 years ago, but I really would like to run QSK. Have I made the right decision to avoid it when running with a vacuum relay?
