Besides other grounding and lightning protection, which have been covered very thoroughly here several times, I have a last line of protection on the RS-232 input to the K3. It's manufactured by (for?) Tripp-Lite and sold as a model DB9.
I'm not suggesting that it replaces any other lightning or surge protection, but for $15 or so, it made me feel better. Amazon sells them (what a surprise!): http://www.amazon.com/Tripp-Lite-DB9-Protector-Suppressor/dp/B00006B81G/ref= sr_1_1?ie=UTF8&qid=1304176459&sr=8-1 or http://tinyurl.com/3d882eq . I also have them on my SteppIR controller, HAL DXP38, and Green Heron controller too. Some will probably say they are a waste of money, assuming you have a good protection system, but at $15 each, redundancy made sense to me. Jim N7US -----Original Message----- Tue night severe T'storms came through the Monroe, LA area. I lost my computer the the Comcast link. After that is when the ERR IO3 made itself known. I'm sermising I receive a spike through the RS232 cable. Is this possible? My antenna were disconnected along with power. -- RC KC5WA ______________________________________________________________ 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
