Transponder prob..
Last post on wrong thread. DOH!
"soxinbox" wrote in message news:... You can buy a cheap multimeter at radio shack for about 10 bucks. Put it on continuity and you are good to go. I know it is not as fun as building it yourself. Just think of it as a kit with one part. "TaxSrv" wrote in message ... "Dave" wrote: Yup... more info.. tech here says there is a timing circuit that gets initialized when switched is closed. I can hear the switch "click" off when released.. He suspects the IC or something associated with it... The bummer about that the King VLSI chip is absolutely nothing in function like the 3 gigahertz Pentium CPU in our now cheapie damn computer, enormous heat sink now and all that. The service manuals always say to suspect the big IC last. Disheartening, when you see King's pricing on a 20-cent, common transistor. I was in an avionics shop once, and spotted a bin of them common transistors. Does FAA actually allow them to use those? And do they like just bill $$ that way per invoice? Oh, the joys of owning airplanes when it comes to genuine proprietary parts, the VLSI, in avionics boxes we think are all that complicated, but to a good tech guy really ain't. Fred F. |
