Whitewright PD rarely use 155.655 anymore. City Hall used to use it, but I have not heard much lately. Whitewright PD of course is digital, everyone on Grayson Co. is.
Gainesville is moving to VHF. They have two new Narrow band licenses, One will be a Repeater which is up, just not programed. The other will be Fire Ground. Gainesville PD also have new frequencies (also 7.5 Khz Narrow band VHF) I'll give you the repeater pairs later this or next week, then when they go on the air, I believe next month I'll submit the update. They are still trying to hash out the CTCSS Codes.
TXDOT Collin Co DO in fact use Nextel. I saw a guy in a sander during the ice storm who had a Nextel and two pagers, Both Alpha's. Dallas Co. units do to I believe because they are no where to be found anywhere else.
My 106 took a dive this morning. Worked fine yesterday, tried to turn it on this morning and it would not power up. Checked it on fresh NiCAD's and another power source and nothing. Trying to get it exchanged now. Other wise it'll go to the service Center. My days is starting bad already.
