Let us assume:
* 50 % TX/RX duty cycle (i.e. a 'run' station in a contest)
* 35 wpm
* 50 units per word ('Paris' standard)
* 14 relay operations per word (based on 'Paris', using full break-in
QSK)
* 35 (wpm) * 14 (operations/word) * 50% * 60 (min/hour) = 14700
operations per hour
* 2 million operations / 14700 operations per hour = 136 hours
* 136 / 24 = 6 days
Vacuum relay life is very roughly about three contest weekends
cheers,
Gerard, AA3ES
