• 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.

DRC-200 Programing Cable

Hi all,

I have recently picked up a DRC-200 repeater, and I am looking at building a programming cable vs buying one. Does anyone have plans for one? Is it a straight serial to mic jack, or does it have more components than that?

Nowhere near a paved road, away from the maddening
DRC-200 Programming Interface and notes

See attached PDF for the programming interface.



For this program to configure / read a KRD Series Repeater, the
following is needed:

A. An IBM-compatible computer with at least 256K Bytes of

B. MSDOS 2.1 or higher operating system.

C. An IA4500 Interface Adapter.


The IA4500 Interface cable with DB25 connector connects to the
computer serial communications port, COMM1 or COMM2. The 6 wire
flat cable from the IA4500 plugs into the REPEATER MIC Jack.
There is logic signal level conversion circuitry within the
IA4500 DB25 plug assembly.

1. Connect the IA4500 Adapter to the computer's COM1 or COM2 port.

2. Connect the 6-conductor reverse-wired Modular cable to the
IA4500 and to the Repeater's MIC Jack.

3. Turn on the Repeater. The Repeater should emit a Beep.

4. Insert the disk. (It is highly recommended that a WORK COPY
be made of this disk and only use it for actual programming
purposes. The program is menu-driven for all pertinet commands.

5. Type in DRC200 and press ENTER (or RETURN) for COM1, or type
in DRC200/2 and press ENTER for COM2.
