*I have a K2/100 I built in 1999 and I added some of the modes through 2005. I retired in 2009 and moved to Florida. * *There is a ham that does up dates and filter alignment. I no longer have a good bench for this work. * *Can someone tell me the name and address of this K2 expert. I think I talked to him a year or so back.* *Thanks* *Art WA8VSJ*
