There are, unfortunately, several listings in the repeater guide that for various reasons are not operating. But, is it possible the problem is with the way you have your radio(s) configured? In a previous post, you wrote The Cobra is not repeater capable. However, both the Zastone and Icom radios should work just fine. The issue is those are not specifically GMRS radios. They are general purpose UHF radios that must be properly configured to operate with a GMRS repeater. The Zastone can be configured with CHIRP. The Icom requires custom software. I believe the version you want is ICOM CSF3001 PROGRAMMING SOFTWARE. A Google search will turn up a few purchase options. Then, for both radios you will need the correct programming cable. Once you have everything together, you should be able to program the radios and access a repeater. Just remember, the Transmit frequency is always 5mHz higher than the receive frequency. For example: Transmit on 467.5500 mHz and receive on 462.5500 mHz. If the repeater requires a tone (digital or analog) to operate, you need to set that under your transmit settings. To get started, you do not need to enter a receive tone, you can set that later after you have everything else working. If you need help with a specific repeater you can post to the Private Discussion forum and include the frequency and tone information.
