• 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 just bought my first CB a Cobra 138 used and dusty from a local flea market for $5. In the process of cleaning it, I pulled off the channel knob and now I have no idea what channel it's actually set to. The knob will go back on in any position as it is not keyed. How do I put it on so that what reads "CH1" is actually CH1?

Thanks in advance,

Tim

First of all you can key up the radio, transmit and ask what channel you are on (if or when you hear some one talking) or better yet hook the radio up to a frequency counter note what channel (frequency) it is on and remove the knob and re install it to show the proper frequency. Hope this helps.

If you have a scanner that can cover CB, fire it up, key the mic on the CB, and see where the scanner stops.

Or get another CB and flip through the channels while keying the mystery meat.

Once you know where you are, pull the knob and replace it so it reads the correct channel.

If you are able to power up the radio and have an antenna or dummy load rotate the dial till you are unable to transmit or receive This will be the blank channel....

Turns out a friend has a CB in his motorhome so we were able to use that to get it all straightened out. Thanks!
