• 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.

I am looking for a schematic/manual for a "Vibratrol modulation monitor oscilloscope" Date on the printed circuit board is 1965. It came to me as "parts or repair". Some components (resistors) have been removed some others replaced. I need to verify values. I would rather not have to reverse engineer it. Looking at the "internal load" resistor wattage capability this was a CB product. BTW anyone else ever seen one?

Hello Corbra 949:

This a shot in the dark about the "Vibratrol modulation monitor oscilloscope"

Look at CBTricks,com the link I have left for you hear, look under JB-1000 these were made a few years back as monitoring scopes. These are the only CB type monitoring scopes I know about.
