• 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.

It isnt software, they are, apparently, two different kinds of RIB boxes. But i don't understand the difference and I want to figure out which i want.

I'm not aware of any difference in functionality between the two. The 'B' is just a later rev level, so I suppose that would be better. You don't get into any real differences until you get to the smart rib. If you're just trying to program radios, either will work. If you're trying to flash radios, neither will work.

So Cali
Just differences in the construction, type of componets and housing for the RIB. Some older RIB's do not have the battery option but do have the power jack for 12 volts.

Factory RIB's do have problems on some computers as the RIB does NOT follow the RS232 standard.

Updated road map here: http://batlabs.com/images/rib_mod.jpg

Notice the component value changes and this one has a standard DB25 connector going to the computer.

The RLN4008, RLN4008A and RLN4008B all have "through hole" mount components and can usually be repaired on a bench. I don't know about the RLN4008C. The RLN4008D and later are all surface mount components and are pretty much, non field repairable.
