WRQV660 Posted March 11, 2023 Report Share Posted March 11, 2023 I am relatively new to the GMRS world. I am trying to learn more about setting up repeaters on my radio. I have been unable to find any GMRS repeaters listed near me. However, when I am on GMRS Channel 16, frequency (462.575000), I have noticed a short broadcast of Morse code about every 11 minutes or so. I am under the impression this may be a repeater identifying itself. I have tried using two radios set to repeater 16 with the offset of +5 and no tone settings in hopes of being able to access the assumed repeater. I had no luck. I have a Wouxun KG-935g, so I went into chirp and turned on "Scan Mode Tone Detect". I then set "Tone Scan Save" to "Tx/Rx". I waited for the Morse code to begin broadcasting and started the tone scanning for CTCSS. It ran for hours and cycled through the codes multiple times, and never seemed to identify a code. The scan would stop at the end of every Morse code broadcast, and then resume at the next broadcast. After doing this for several hours I hooked my radio back up to Chirp, and looked to see if anything was saved in it since the radio appeared to never stop searching for codes. I found nothing. I then started the whole process over again searching for DCS codes this time, and received the same results. Am I wrong in assuming the Morse code I hear is a repeater? Is my process for trying to scan for CTCSS and DCS codes incorrect. Hopefully my attempt to explain what I am trying to do makes sense. If you have any suggestions as to what I need to do, please reply. Thank you. Quote Link to comment Share on other sites More sharing options...
gortex2 Posted March 11, 2023 Report Share Posted March 11, 2023 Many LMR repeaters do not transmit CTCSS or DCS/DPL when they ID. Youd be better off decoding the ID and searching the FCC database. It may not be an open repeater. WRUU653 and SteveShannon 2 Quote Link to comment Share on other sites More sharing options...

Your process of scanning is probably correct, but as Gortex2 pointed out the repeater might be sending its ID without any tones. That’s sometimes how repeaters are programmed in order to avoid breaking squelch for any receivers. Your explanation made sense. Record the Morse Code ID and see if you can understand it, or upload the recording here in case someone here can help you understand it.

I agree with both @gortex2 and @Sshannon. To use the radio to scan for tones you may have to wait to hear someone accessing the repeater if the repeater sends an ID without tones. I see one near you on the map, no output tone. Open repeater. Check the map. For repeaters near you. Also click the gear in the upper left hand corner and select stale and offline repeaters. Good luck. Quote Link to comment Share on other sites More sharing options...
