If you notice after "updating" your Jupiter, it may still say the previous version that was there before at power up.... I noticed that the "538V1140.ruf" file is missing.. I had flashed eariler to version 1.12, and the radio still says 1.12.. I think Ten-Tec left the file out.. Thanks and 73's, Dudley WA5QPZ jhurry@austin.rr.com
