There are four methods can solve your question: 1.Switch to other channel 2.Change CTCSS in same frequency 3.Use Squelch function: switch to the largest degree to reduce other noise 4.Purchase a radio with Scrambling function, such as RT1 or RT24

10  Can you tell me what the squelch setting does in chirp? Also I am using these in a big city. What is best to use for my tone setting? I am using DTCS now and it works, but sometimes some radios can hear me and others can't.
Hello Robert, Please set the squelch level in RT22 software, it's affected the environment When the environment is noise, the level adjusted larger to avoid other noise Attached a pic for you reference to set the squelch level Best regards
