• 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:

P25 phase 1 and 2 are both digital correct? Listening to certain TGs when the car/ portables transmit and don’t have a good connection they sound like a analog radio with a weak signal to a repeater, I thought with digital there was no static it gets “pixelated” for lack of a better term.

Phase 1 is FDMA, phase 2 is 2 slot TDMA overlaid on the FDMA channel.

There could be digital TG's that are patched, via the console, or other means, with analog channels.

This is the TG, I was pretty sure they are all phase 2. I’m gonna try to get an audio clip, not that it’s a big deal just curious

Our statewide system here in Ohio is 700/800MHz P25 phase 1, there are some agencies around me who use VHF analog vehicular repeaters tied to the digital radios. Sometimes when they're too far from the car I hear "static" caused by a noisy signal into the VHF analog receiver on the vehicle repeater. It could be what you're hearing, I'm only guessing since I don't know.
