I've got a Baofeng UV-5R and a Cobra ACXT 645, and I'm trying to get them to communicate.

The Cobra transmits and the Baofeng (programmed with CHIRP) receives, but not the other way around.

I've tried different channels, different frequencies, and with the CTCSS and DCS on and off. I'm on day 3 now and have begun pulling my hair out.

  • What am I doing (or not doing) wrong here?
  • Why aren't the radios working like they're supposed to?

I'm a beginner at all this.

    $\begingroup$ The Cobra thing is a GMRS device, right? $\endgroup$ – Marcus Müller Jul 21 '19 at 15:20
  • $\begingroup$ @MarcusMüller I added a link to his post. The domain "cobrafrs.com" may imply that it's an FRS radio. But I know what you're thinking, I can read your mind. ;-) $\endgroup$ – Mike Waters Jul 21 '19 at 22:20

    $\begingroup$ Hello Mike, and welcome to the site! In what country are you planning on using those radios? That can affect some legal issues with using the Baofeng on non-amateur frequencies. $\endgroup$ – Mike Waters Jul 21 '19 at 22:26

    $\begingroup$ The Cobra may be desensing due to too high a signal level at the antenna. Try it with the radios farther apart. $\endgroup$ – Mike Waters Jul 21 '19 at 23:14

    $\begingroup$ Keep in mind that it's illegal in the US for the UV-5R to transmit on FRS/GMRS frequencies except in specific types of emergencies. Even testing the ability is illegal. $\endgroup$ – mrog Jul 24 '19 at 20:29
