• 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.

Can it be done? This is an external speaker that typically comes with a spectra. I know Motorola made the speakers for some Maxtrac's in an either a no ground or negative polarity fashion (can't remember which it was, don't have the site where I read it bookmarked), and things could go up in smoke if wired with your typical speaker. So I thought I'd ask here before I start modifying things.

I understand that there's a dispatcher headset that may be available (I've looked on ebay and haven't found one), and honestly, I'd like to adapt my black gm300 mic to the spectra as well..I've taken a liking to how it sounds and I don't want to be forced into a different mic.

What I'd like to do is mount a 3/4" headphone jack into the back of the speaker. To make it work properly, I imagine I'd have to wire it in a way that cuts off the speaker when plugged in.

Any ideas would be helpful. .Thanks!

My Spectra has a black GM300 mic with LED on it, great combination.

I also have a Heil headset on my Spectra, Bob Heil said "it can NOT be done". I build the interfaces for the headsets.

The Spectra speaker output would require a transformer for most headsets. The output is a bridge amp, so nothing is referenced to ground like most headset earphones.


We are using the Audio Technica ATH 770 Com headsets in the EOC on Kenwood radios. These have a separate 'speaker' input.


Send me a PM, and I will be glad to share.
