• 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.

MC900 programming help

Hello folks,

Good thing I am bald or else i would have pulled my hair out. I am trying to program 4 x VHF MC900 through the Mic port.

I have programmed these radios before with the very same items, now for some reason it's not working. I am using RSS R06.06.00, Moto cables and RIB with power supply. I can program HT-1000, SM-120, Radius 1225, CM-300, MAXTRAC, GM300; Kenwood stuff with same computer and proper cables / software.

The MC900's do not want to play nice. I get "bus data collision on tx error" or "timeout error"

I have tried using my PA-III rib, another Moto rib, another computer, changing batteries in the RIBs, cleaning the contacts and pulling my hair out.

If someone has any further assistance to offer I would greatly appreciate the help.

Thank you.
