• 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:

The fire department i work for uses all kenwood products. Now our problem is we are starting to have severe problems with battery life. we use kenwood tk 3140's and tk 380's on our air packs. The 3140's we carry while on duty. Most of our batteries only last 2 hours and thats when we are not busy. The batteries are ni-mh batteries. What recommendations or options are out there? Is there a setup like the Motorola impress batteries for kenwood? we really dont want to switch to Motorola due to cost issues. Any recommendations will help us!

The most likely issue with the batteries is either age or memory. Do you have battery conditioners? Have the batteries been in service for over a year? A good rule of thumb is to condition NiCad and NiMH batteries every month if used daily and replace batteries (rotate them to non public safety users) every 12 to 18 months.

There is nothing special about impress. It is just the way Motorola brands Lithium-Ion batteries. You should be able to find Lithium-Ion and Lithium Polymer batteries for your Kenwoods but you will likely have to replace all your chargers when you do.

Yep, sounds like your batteries are old enough that it's time to replace them. Rechargeable batteries will not last forever. Getting 2 years out of them in public safety use is about the most I'd expect. Your department really needs to have a program and budget to deal with radio batteries.

Motorola Impres batteries are only made for Motorola radios and they will not be compatible with the Kenwood radios. Impres batteries and chargers have some circuitry in them that allow some record keeping functions, charge cycles, etc. It helps squeeze some more life out of them.

A battery conditioner and plan to properly use it is a good investment if you have a lot of batteries to manage, and the discipline to properly use it.

Even with all that, you are still going to want to replace batteries every 1 1/2 to 2 years.

In the fire service, you may need to get IS (Intrinsically Safe) rated batteries. You can get these from Kenwood.

If you are looking for other brands, I've had good luck with Power Products.
