• 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.

Can anyone explain what the difference is between an 11K0F3E and 11K2F3E emission designator is other than the obvious .2 KHz? On the face of an FCC license is this merely an equipment issue?
Thanks

It's essentially the same thing. The difference could be accounted for by something like the highest modulating frequency. Example:

3.0 KHz highest modulating frequency and 2.5 KHz deviation would be 11K0F3E.

3.1 KHz highest modulating frequency and 2.5 KHz deviation would be 11K2F3E.

11k2f3e refers to 11.25kHz of occupied or authorized bandwidth.
The highest modulating frequency is 3.125kHz.

12.5kHz and 25kHz refer to the channel bandwidth or spacing. The authorized bandwidth is narrower than the channel spacing. The emission designator (11k2f3e for example) tells the authorized bandwidth and the modulation type.

Is there a program out there that will decode the emission code and tell you the band width and modulation without having to remember what all those Numbers and letters mean.

Thanks,
Bob
