• 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.

Set them for On/Off & Ignition. They won't require the ignition sense to power up, but you will have to turn them on manually by pressing the center of the volume knob.

I could not agree with this more!!! If you ever set for ignition only, when (not if) the ignition circuitry in the radio goes bad, you can never turn it on.

I did not mention shorting pins 7 & 9 off the cuff. I do radio installs and repair as a profession every day at work. This is an un-documented method of bypassing the ignition sense. It works and I have radios on my bench and in the field in service that I have done this to. I did not make it up.

have you ever had any issues after a while with connecting pins 7 and 9? i just did it and it worked but i just wanna make sure it wont damage or cause any issues in long term!

As others have said, it's a work around, and only works if the pins are set up correctly. It won't hurt anything, but it's not a long term solution. The right way to set it up has been mentioned:
On/Off + Ignition sense in the programming. Pin 10 to ignition switched 12 volt source. Wire the power for the radio directly to the battery, do not use the cigarette lighter. Those are a serious source of RFI in most vehicles.
