• 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.

I've been looking for information on the Motorola Spectra DA3KX which I received for free recently. I called up Motorola and they were happy to check and see if they still had information on it, but they said they had no information regarding it. If anybody has any information or documentation on this thing, that would be amazing. It's really elusive and I'd like to get it to work on the amateur bands since it is a VHF model.

Try this BatLabs page:

There's probably a wealth of information over on repeater-builder.com also.

There's two VHF models:
  • Range-1 136-162 MHz
  • Range-2 146-174 MHz
If you've got a range 1, then you're all set.
If you've got a range 2, then you're good down to 146, but I'm pretty sure I had mine down lower, at least into the upper 144MHz range without any challenges. It's been a LONG time since I touched a spectra, so I don't remember what the steps were off the top of my head.

Be aware, these are notorious for leaky capacitors. Free is about the right price to pay for one of these.

The shift trick should work on them to get them just a ltitle lower.

That's jiggling the memory. Pretty sure that was the trick. I've still got that radio in a drawer and I had it programmed for a repeater that had an input at 144.850.

But I'm sure the capacitors have crapped the bed. The display was getting weak when I last used it (probably 15 years ago).

Awesome, thank you!

On the label post the ID number. The spectra model number is useless for band identification vs other motorola model radios.
