• 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.
  • Effective immediately we will be deleting, without notice, any negative threads or posts that deal with the use of encryption and streaming of scanner audio.

    We've noticed a huge increase in rants and negative posts that revolve around agencies going to encryption due to the broadcasting of scanner audio on the internet. It's now worn out and continues to be the same recycled rants. These rants hijack the threads and derail the conversation. They no longer have a place anywhere on this forum other than in the designated threads in the Rants forum in the Tavern.

    If you violate these guidelines your post will be deleted without notice and an infraction will be issued. We are not against discussion of this issue. You just need to do it in the right place. For example:

As with most Motorola mobiles -- NEVER use Pin 1 or Pin 16 unless attaching an ACTUAL speaker. Grounding or even accidentally loading pin 1 or 16 in an incorrect manner can release the life-time supply of smoke from the audio amplifier IC.

Be aware that there is a DC bias voltage on the filtered RX audio pin. You might have to add a 1.0 uf capacitor in series with the connection to block the DC voltage coming from the Motorola radio if your device being fed doesn't provide for it.

How would you recommend obtaining audio from a mobile for streaming?

This entire thread is devoted to doing exactly that. The answer to your question is contained in the previous posts.

For a CDM with the 20 pin accessory connector, please re-read Post #3 and pick the "Buy Your Own".

If you have a Motorola with the 16 pin accessory connector, the same seller offers the same kit with a 16 pin mating connector. It's his cable #61.

It doesn't get any simpler than this.
