• To anyone looking to acquire commercial radio programming software:

    Please do not make requests for copies of radio programming software which is sold (or was sold) by the manufacturer for any monetary value. All requests will be deleted and a forum infraction issued. Making a request such as this is attempting to engage in software piracy and this forum cannot be involved or associated with this activity. The same goes for any private transaction via Private Message. Even if you attempt to engage in this activity in PM's we will still enforce the forum rules. Your PM's are not private and the administration has the right to read them if there's a hint to criminal activity.

    If you are having trouble legally obtaining software please state so. We do not want any hurt feelings when your vague post is mistaken for a free request. It is YOUR responsibility to properly word your request.

    To obtain Motorola software see the Sticky in the Motorola forum.

    The various other vendors often permit their dealers to sell the software online (i.e., Kenwood). Please use Google or some other search engine to find a dealer that sells the software. Typically each series or individual radio requires its own software package. Often the Kenwood software is less than $100 so don't be a cheapskate; just purchase it.

    For M/A Com/Harris/GE, etc: there are two software packages that program all current and past radios. One package is for conventional programming and the other for trunked programming. The trunked package is in upwards of $2,500. The conventional package is more reasonable though is still several hundred dollars. The benefit is you do not need multiple versions for each radio (unlike Motorola).

    This is a large and very visible forum. We cannot jeopardize the ability to provide the RadioReference services by allowing this activity to occur. Please respect this.

So, I have a question. So if a city has four frequencies licensed: say they're:

453.000
453.025
453.050
453.075

So, channel one is 453.075, 2 is 453.000, 3 453.025 and four 453.050 anyways my point is:

Why don't they just go in order?

1 453.000
2 453.025
3 453.050
4 453.075

I'm just wondering if there is a meathod to how frequencies are arranged in a radio. Thanks

In my county, we had Channel 1 first, added Channels 2&3 a few years after, and added 4 years later. Maybe just the way the FCC gives them out? It is the government, after all.

It could be that they expect lots of activity on channel 1, significant activity on channel 2 and only minimal on channels 3 & 4. If they set things up quite a while ago the radios may have issues with bleedover from adjacent channels so they made the two with the most expected load the widest apart frequency wise and those with lesser expected load inbetween to reduce the possible adjacent channel interference.
