• 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.

My local park rangers use an analog conventional radio system in the 151.xxxx VHF range... the channel known as "Secure" or sometimes they call it "Channel 2" sounds kind of like aliens talking. It is a repeated channel, both radio channels use a DPL of 023. (This is not in the database so...)

But sometimes it hard to tell because the repeater doesnt have the open air time that some repeaters do. (I mean after they click the button the repeater goes off, it also sounds the same on their input frequency when they are talking over the repeater no air open time after the TX) I hope this is making sense.

I can confirm they use the TK-2302VK for their portable radios. Not sure on the car radios, the reason they wanted to buy the new portables in the first place was because the car radios were starting to break....and they don't have the money to "go digital". I know this because I was at the town meeting when the bid was happening. Anyways, they said they bought no extra hardware to encrypt their transmissions... so any help in finding out what kind of encryption would be "standard" on a TK-2302VK Thanks!! would be very helpful! :) BTW I am using a Uniden BC72XLT to monitor... not sure if this matters or not.

Thanks!!

It is probably "voice inversion". "ch 2" is probably the same input and output frequencies but the voice inversion is enabled.

So, could I buy a radio like theirs and just program RX freq, the DPL tone and the voice intervention code they're using or would that be a no-no?

Yup, you could.

You could even try downloading the old invert.exe program for your computer. You feed it audio from your scanner and it normalizes the audio and plays it out the PC's speakers.

As for the legality of it, I don't have a clue. If you are successful, I'd keep it quiet and enjoy it.
