I have noticed a significant difference in the brightness of the LEDs in my XV144 and XV50 transverters.
Sorry there are no serial numbers, but my XV144 was purchased in July 2004 (with Manual Rev.B, November 7, 2003). My XV50 (now modified for 70MHz) was built according to the Assembly Manual, Rev.C 22 January 2007 & Owner's Manual Rev.D, April 11, 2007. The LEDs on the, later, XV50 are very much brighter than the earlier XV144. Both have exactly the same supply voltage of 13.95V. Comparing the component values and front panel schematic diagrams of both transverters, they appear to be identical. I would interested to know whether other people with multiple XV transverters are finding the same differences in brightness. Could it be that Elecraft changed the types of LED supplied in the kits over the years? 73 de David G4DMP -- + - - - - - - - - - - - - - - - - + | David M Pratt, Kippax, Leeds. | | Website: http://www.g4dmp.co.uk | + - - - - - - - - - - - - - - - - + ______________________________________________________________ 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
