• 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.

Cobra 19 Ultra III Without an Antenna

I have been working on getting a Cobra 19 Ultra III radio installed in my truck along with a PA system. So far, I've mounted the a 50 watt Powerhorn speaker in my truck and have it ready to connect to my CB, however, my Firestik Firefly antenna, mount, coaxial cable and SWR meter has not been delivered in the mail yet.

Does anybody know if there is anything wrong with using my CB radio standalone as a PA system for now while I wait for the rest of my parts to deliver? I have read that it is bad to run a CB radio without it connected to a tuned antenna from other forums and Reddit posts; does this apply to the Cobra 19?
Any information would be helpful as I have already emailed Cobra about this issue through support@cobra.com and have yet to receive a reply from them.

Thank You,

Should be ok

Hello
asianfromthecongo

You should be fine as long as the radio is in PA MODE only, if you key up in non pa mode then it might do harm, If you accidently key for 1 second you might be ok but any longer than that will damage the radio.
And sometimes when you don't have an antenna hooked up your radio might blow a fuse. That happened to me before, don't know if its a coincident or what..

You can key up most CB radios for a very long time with no antenna and more than likely nothing will happen. I've done it countless times trying to damage radios on purpose and never caused a problem. This was wrapping the mics with a rubber bands, no antennas connected and coming back hours later.

I just finished wiring my PA speaker to the CB; everything is working great! I'll just make sure to keep the PA button pushed in on the Cobra 19 until I get the rest of my radio parts delivered in the mail later this week.

Thanks again for the help KB0VWG!

Thank you for the quick reply prcguy!
You've definitely helped clear some of the anxiety I had about breaking my CB before I could get the antenna installed.

Still, if you don't mind answering, why in the world were you intensionally breaking CB radios? haha


Thanks again,
