• 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:

I want to use a few of these GP300s as casual hiking radios but I need new batteries. There are Ni-MH batteries online. I have an older charger but I don't know if the chargers from 20 years ago supported Ni-MH. Trying to figure out which Motorola Charger Model# is NI-CAD only and which revised model supports Ni-MH Chemistry?

Thanks

I don't know, I flushed all my old Motorola binders years ago.

If you get in a jam, there are companies that still make chargers that will support these radios, with NiMH or NiCad batteries:

There are a few mods for the GP300 chargers that handle the NiMh batteries.

Which charger do you have?

I have the HTN-9042A intellicharger. No Manufacture date stamp. Some sites spec it as both NiCad and NiMh. Others say just NiCad.

The intellicharger rapid rate series was supposed to adjust the charging based on the chemistry of the radio inserted in the charger. In short, it should be able to handle both your NiCad or NiMH batteries.

The slow rate chargers were the ones that handled NiCad only as I recall.
