No it definitely isn't and you gotta read the manual, it's pretty explicit about this. > In WWII the military solved this ghastly problem by having a gazillion > multi-pin plug and socket layouts, so you could ONLY plug something in > where it actually matched up wire for wire.

Alas, my friend Leo Endres, engineer and philosopher was right when he said, "The problem with Lessons Learned is -- they rarely are." A well known USAF stealth airplane of moderately recent vintage, which really didn't want to fly and, left to its own devices, had the glide angle of a brick, so it was totally dependent on its electronic stabilization systems. Even moving on the ground, the control surfaces were constantly correcting. Unfortunately, it did allow [at first] the pitch and roll gyros to be misconnected which happened once to my knowledge. Scream down the runway, pull the stick back, turn over inverted and ... land. Pilot walked away, thank God. This situation also exists inside the K2, the 12VDC and RF connectors to the KAT2 or KAT100 if they're there, will gladly interconnect with not great results. All it takes is some real care when you're doing things in there, sort of like paying attention when you're driving. Try not to have a glass of wine or a beer with dinner before working on your radio. 73, Fred K6DGW - Northern California Contest Club - CU in the 2012 Cal QSO Party 6-7 Oct 2012 - www.cqp.org ______________________________________________________________ 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
