Lucien, many thanks for your help. I am ashtonished. It is incredible that a great rig as the K3S doesnt have the simpler debouncing circuit on the key input, input obviously available for all mechanical kind of key, so with potential bounces. This afternoon I have written to elecraft support informing them about this problem.73 Ian IK4EWX

Even my K2's will behave strangely, though not quite as bad as the K3 and s. It's not a problem with the rig; it's just a contact bounce issue, so you'll just need a debouncing circuit. Either an external keyer (most of them have debouncing circuitry in them) or you can home-brew one. There are a couple good circuits in the list archives. A capacitor across the bug terminals will help, say a .1 uf, but beware that it'll key the rig momentarily when you first plug it in as the cap charges. 73, LS W5QD -- View this message in context: http://elecraft.365791.n2.nabble.com/K3S-losing-swr-wattmeters-indications-on-tx-please-help-tp7618984p7618995.html Sent from the Elecraft mailing list archive at Nabble.com. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected] ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected]
