• 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.

XTS 5000 Audio clips, and stops

I recently acquired an XTS 5000 UHF. I am monitoring multiple analog frequencies and I noticed that a lot of them get clipped. When it's loud, like the MDC burst, or just the dispatcher speaking loudly the audio becomes extremely distorted and clipped, in addition it also just cuts it out completely at those parts sometimes. This is happens regardless of the volume set through the volume knob, and also happens with a shoulder mic and speaker, the same as the internal speaker. I also tested this with FRS where I was transmitting with another radio and I noticed this issue when I was speaking slightly louder. I have an XTS 3000 VHF and have no experienced something like this. On CPS I tried to enable advanced RF AGC, but it made no difference. I don't know if it's just a configuration or the radio has a hardware issue. Any help is appreciated.

It looks like I got the channel spacing wrong, apparently these UHF frequencies are mostly wideband, I thought there was a requirement for public safety to be narrow band. All of the VHF channels I have on the 3000 are narrow. 1 channel on the UHF is also narrow, and I thought I occasionally heard clipping there also. Will test and see how it works now that I changed them to wide on the proper channels.

Where are you, and what part of the UHF band are you listening to?

Since I changed the frequencies to wideband most sound much better without really clipping, I am not located in that county, so I will have to travel there again to properly test it. There is one department however, Redwood City PD which from the 20 miles I am monitoring it from still does sound like it might be clipping, but all the rest are not. The narrow channel that is in my county is an EMS paging with two tones being used, the dispatcher talks over the tones, and then it sounds weird like I described, but it sounds the same on SDRs. They have the dispatcher multiselecting and transmitting on 3 channels at a time, that department is actually on a P25 Phase 2 system.

Is that something i can do myself?

No, you need test gear to do it.

UHF R2, San Mateo County in California. 453.1 is the one that is narrow 482-490 mhz then all these were wide

T-band was exempt from narrow banding requirements, because it was to be auctioned off. Some T band users did narrowband, but many did not.
