If you ask nicely they might give it to you. Are system keys public?. If I am a tax payer I have the right to use something I am paying for. If we are going to give Motorola billions of dollars for public safety radios, then I want the system key to program up my Motorola for NAS. Besides who needs system keys anyway?. Motorola leaked a DOS system key generator so too bad for them. Lax security is their own fault. When has an end user been prosecuted for possession of a system key. Never once, never will be either. NAS works great when programmed properly. I just get tired of the radio police saying get a scanner. You want to buy me a $800 SDS scanner?. Then I will get a scanner. Actually the SDS series of scanners are junk!. Lot's of quality control issues, they hear only about 50% of the radio transmissions. For that $800 price tag, they need to work and not have numerous quality control issues. Easier to pay $50 for a used XTS or XTL that works great. CPS is free so the cost of a NAS setup is cheap!!. I have no problem that someone screws up the programming and the radio gets inhibited, radio system stays secure. Remember it's the "BIG E", not the "LITTLE E" but the big bad "E". I guess the word encryption is banned here on RR. I think if folks call it the BIG "E" then it won't be encrypted and the people think they have the right to monitor encrypted radio comms. News flash!!, you have no right to!!!
