• 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.

Is anyone else here familiar with this system? I have a 396 and 996 that are both experiencing the same thing. During the middle of sentences, the transmission breaks up, and somtimes that is it for that transmission. Somtimes it is just garbled. The status screen shows that it is decoding at the default threshold of 10, after watching it for a while. So I guess that does not need adjustment. Other APCO25 systems Glendale PD, Maricopa County, work fine. Both the 396 with it's duck antenna, and the 996 with a rooftop antenna, do the same thing. I could possibly understand it on the portable with the duck antenna, and 1-2 bars of signal, but the 996 with rooftop antenna is pegged at 5 bars on every frequency, every time. Signal strength is not an issue. Ideas?

(Darn, I sure do miss the old VHF system where a good scanner and outdoor antenna were all you needed.)

one thing to try is using attenuation as the signal may be overloading the front end. Strange as it sounds, signals can be too strong.
