Hi all, My KPA100 manual shows five possible settings for the PA parameters, one of which - tPA - "allows TUNE mode to display heat sink temperature" My KPA100 has firmware v1.06, but will not display tPA: all I can get is OFF, ON, Fx.xx, and E. Is it me, or is this function not available in v1.06 ? 145, Pete PE1MHO - G7ECN - M3ECN K2 #2768
