I have never seen such rude people.
You ain't seen nuthin, yet.
Here's why people are rude about this. A properly programmed trunking radio requires "system keys" to program. The software simply WON'T let you program trunking systems without it. System keys are considered proprietary to the particular system, and are closely guarded by system administrators. Unless you work at the radio shop maintaining the system, you're NOT going to get it.
Programming a radio requires an ID number to be assigned. On the off chance that you actually had the right keys, randomly choosing an ID can cause interference to the operation of authorized users of the system. It can pull that ID's affiliation to other talk groups or parts of the system, and cause the authorized users to miss calls. Duplicate ID's in a system can wreak all sorts of havoc. Even if it's not a duplicate ID, selecting a talkgroup in a part of the system it's not normally used can create channel loading problems, because many systems don't even transmit a talkgroup out through a site unless there's actually a radio affiliated to it. If it's YOUR radio causing the affiliation, now a transmitter is being occupied by an unauthorized user wanting to listen.
A trunking radio contains a transmitter, and the radio affiliates with the system, causing it to actually transmit a signal. If you're not authorized on that system, that affiliation transmission is illegal.
Every time you turn the radio on, or change the channel, the radio affiliates. So, merely listening in is NOT a passive act, like it is with a scanner. That radio becomes one with the system it's monitoring, and YOUR operation of the radio can direct how and where and whether the entire system radiates a particular talkgroup.
It is for this reason that people who are new to radios and come on here asking about things like putting an APX on a trunking system when they clearly do not know raises all sorts of alarms.
