• 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.

Over the years I've seen threads regarding a method to determine the LCN for an EDACS system. Naturally when I needed to find those instructions, I couldn't. So can someone post the methodology or a link to a thread describing the process. I do recall that two EDACS compatible scanners are needed. Thanks for your assistance.

DO NOT ASK ME FOR HELP PROGRAMMING YOUR RADIO. NO.
Basically it's a matter of listening and watching for an active channel and looking at the channel steering data until you correlate frequencies to active channels as they're being called up.

It's much easier when system activity is low. Late at night and NOT on a weekend or full moon night.

Having access to a spectrum analyzer with a hold function is very helpful. Even better if it has a waterfall plot function that allows you to record and play it back.

There is no simple formula for doing it. You just have to grind away at it until you don't miss any transmissions.

Or...there is a way. Check this site's database. If it's an EDACS system, those are end of life and being retired and new ones haven't come up in quite a few years. So the odds of this site having the required information in the database are very high.

If you have the ability to use UniTrunker on the control channel and a regular scanner with all the frequencies programmed in conventional mode, it can go fairly easily. If the channels are used in sequence and you have a list of frequencies used (FCC data), you could figure it out in a few minutes of activity.
