• 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.

Just curious............

Using UHF CCR's at 2 watts we can get 3ish miles in the mtns.
As for transmitted signal strength vs distance, here is the best way I know to splain it.
Remember the old CB's with the analog meters? If you are hearing me at a 5 on the meter, I would have to 4x my output to put a 6 on your meter. To make it a 7, it is another 4x. So in the above example, 4 watt was 5db, 16 watts made 6db, 64 watts pushed it to 7db. Now if I want to make it 8db I'll need to transmit at 256 watts.
Does that make sense? hope so. I really am a poor teacher....

Can I suggest that you do some homework on the numbers your throwing around.

An example of what you should be saying is if you start out with 2 watts, you need to double the power to 4 watts to get an additional 3 db. The next step would be 8 watts for an additional 3 db bringing you up to a plus 6 db. Going from 8 watts to 16 watts, you get another 3 db gain. That now has you at a plus 9 db over the original 2 watts.
