• 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.

Earlier this year I posted this thread regarding APX audio output via 3.5mm. One of the members here posted the exact link I was looking for, but I'm at the point where I'm looking for a similar cable available to APX 4500 mobile radios. I need a cable that will output to 3.5mm, which I can plug into PC's to feed audio. This will be feeding encrypted audio, so a scanner is not possible.

I've done a few google searches and turned up nothing. Does anyone have any ideas?

I have not seen on made commercially yet. What I have done is take the accessory cable and add a wire for audio. Pin 21 is filtered audio which is a set level. You need ground from Pin 14. Put what ever flavor of connector you want on the other end. I normally terminate to an RCA as they are feeding an amp. You can grab the pins on ebay or other MSI sources.

Not required to use but if there is a power outage you'll have to manually switch on the radio again with the power button. With ignition sense and program set to Soft Power Off the radio will automatically come back on.
