• 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.

When adding channels to the scan list you have the option of selecting it as priority 1 or priority 2. I read the manual but still do not understand what this function actually does. Maybe it checks the channel for Activity while stopped on another? Just unclear on this.

It's a tiered priority. Pri1 takes precedent over Pri2.

When the radio stops on a non-priority channel, it checks both priority channels for activity. It will tune to either if there is activity. If it tunes to Pri2, it will continue to check Pri1 for activity, and will switch to that channel if it detects any. If the radio is already on the Pri1 channel, no further checking takes place until the radio resumes scanning.

Ok thanks. What if it is receiving something on the selected chAnnel (non priority) will it still be checking my priorities?

If you don't set Selected as a priority channel, then it's no different than any other non-priority channel.

Set/Clear Priority 1
Toggles the Priority 1 scanning status of the highlighted conventional channel/trunking personality in the Members list. When the Priority 1 status is set to the highlighted channel/personality, the Priority 1 status on another channel/personality (if any) is cleared. During scan, 50% of a radio's scans are on the Priority 1 member. If a Priority 2 member exists, scans for the Priority 1 member are reduced from 50% to 25%. Even after landing on a non-priority or Priority 2 member, the radio continues to periodically scan for transmission activity on a Priority 1 member. If the radio discovers activity on the Priority 1 member, it drops the current transmission, and unmutes to the Priority 1 member.
