• 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.

I got a frequency list from a local department and have a question on the RX PL and TX PL... One of the channels has D411 under RX PL and TX PL and another channel has D606 under RX PL and TX PL.

The software allows me to input for example "203.5" under RX and TX PL's, but what does D411 and D606 mean and how do I program that?

Any help would be greatly appreciated! Thanks

D411 and D606 represent DCS - Digital Coded squelch (or DPL - digital private line) codes. This technique uses a binary bit steam encoded in the signal and not just a sub-audible tone used in CTCSS/PL.

If your radio/software supports DCS/DPL, then you should see a list of codes to use - typically starting D023N in the pull down list after the 250.3Hz PL tone. You haven't said what or how you're trying to program.

Setting no tone on the Rx and Tx frequencies will allow you to hear all traffic on that channel, irrespective of what PL/DPL tone is being used.

Thanks for your help. I am programming a Kenwood TK 280 with software KPG49D.

I added the D606 and it converted to "D606N". After writing to radio i was able to key up the tower and hear dispatch clearly, so I'm assuming it worked.

On the Kenwood software when you are using a digital code squelch (DCS) tone, after you select D606 for example, it will show in the programming software as D606N. That is normal. Sounds like you got it working okay, good job.
