Gary.....Actually, I use FreeScan program software for my 996xt and the P-25 option is not there under MODE! I set that to "AUTO" and under "Audio Type", I set to Digital! I have a column for "NAC" and I just put in the NAC numbers!
After doing a little reading about the 106 scanner, you can set these frequencies to the 'P-25' mode!!!!!!.. the info below came from: "Easier to Read Pro-651/652/106/197 - WS1040/1065 - PSR 500/600 Digital Scanner Manual"
