Actually the only common relays that MIGHT be a problem are certain automotive relays intended for intermittent duty use. Some horn and starter relays are not designed for continuous duty. :-) > Relay speed is not a consideration, it will pull in when the K3 is > turned on, and will stay in that state until the K3 is turned off, so > operating time is not a factor, only the contact current rating (must be > sufficient for whatever accessories you wish to power), and the relay > coil must respond to 12 volts and draw less than 500 ma. Which is almost any relay except certain automotive relays. A 6 watt coil is very rare, except in really big relays. Most traditional power relays in the 15 amp contact range will be 150 mA coils or less and cost a couple bucks from mail order houses. 73 Tom ______________________________________________________________ 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
