• 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.

Ok, I now know that the narrowband requirement does NOT apply to GMRS,...BUT, what I'm asking here is:

Q: Is the use of narrowband ALLOWED in the GMRS service, or is ONLY wide-band allowed for use in GMRS? (ie, can I use a radio that is on a GMRS frequency and set for narrowband TX/RX on that freq, or does *** TX/RX have to be in wide-band format while on a GRMS freq?)

Long answer: The FCC sets a maximum allowable bandwidth. As long as you are using an approved modulation method (i.e. FM), they don't care that you use less bandwidth than allowed. Otherwise, it would not be allowed to talk quietly into the mic (FM bandwidth varies with the level of modulation).

Short answer: Yes.
