Abstract
- The author describes his relay-based QSK switch that will work with any amplifier. Topics discussed include reason his QSK switch for HF amplifiers was expensive, comparison between the Jennings RJ1A vacuum relay and the Panasonic DK1a1b relay, and information on the timing of the high-current Panasonic DK1a1b amplifier relay with no additional turn-off delay.
