• 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.

Motorola RMN5050A

I use a RMN5050A desk mic on two Motorola mobile radios. I don't have the proper test equipment to measure frequency response and such. I have a XPR 4550 and XTL 5000 high power. Other operators state that the tone of the mic is too high and the bass frequency response too low. I have disable AGC on the mic and in the CPS. Is this typical for this microphone? Am I missing some adjustments in the CPS. Are there any modifications to improve performance? Is there a better desk mic for Motorola radio with a modular plug?

There's a potentiometer on the back of the unit that allows you to change something (I believe it might be gain). There's also switches inside if you take the bottom of the mic off with screws
