kbussche Posted April 20, 2023 Report Share Posted April 20, 2023 Does anyone have an example or screen shot of what a GMRS channel with a privacy code looks like in chirp? Not sure what mode or tone needs to be set. Quote Link to comment Share on other sites More sharing options...
1 SteveShannon Posted April 20, 2023 Report Share Posted April 20, 2023 First, it is possible with Chirp. The squelch types are typically: None - This means that you don't send a tone and you don't expect a tone. Tone - This means you send a so called privacy tone which (CTCSS which is also called PL, or DCS, which is also called DPL), but you do not filter based on what you receive. TSQL - This means that you send a privacy tone and that your radio will only break squelch to allow messages to be audibly reproduced when the privacy tone sent by someone else matches what your receiver expects. If you want to use privacy tones on simplex you and your partner would arrange in advance for which tone each of you would send. It's usually easiest if you both have the same tone, but you can split the tones also, so you transmit one (TX_CTCSS) and your partner sets the RX_CTCSS to match and going the other way your parner transmits a different tone (TX_CTCSS on his/her radio) and you set your RX_CTCSS to match that tone. But, you must understand something: Anyone who leaves their RX_CTCSS empty (or sets their squelch type to TONE) will hear everything transmitted on that channel. The only thing a privacy code does is help keep you from being interrupted by everyone transmitting without the same tone your receiver listens for. kbussche 1 Quote Link to comment Share on other sites More sharing options...
1 back4more70 Posted April 20, 2023 Report Share Posted April 20, 2023 Here's an example of a couple of my entries: Line 31 is for GMRS, and line 32 is for "FRS" (in quotes because it is programmed on my GMRS radio). kbussche 1 Quote Link to comment Share on other sites More sharing options...

Not sure what mode or tone needs to be set. It’s really going to depend on what your local repeater requires. Which version of Chirp are you using and what does your repeater expect? Also, Chirp may have the ability to program itself based on Repeaterbook. Quote Link to comment Share on other sites More sharing options...
0 kbussche Posted April 20, 2023 Author Report Share Posted April 20, 2023 Oh, I am not looking to setup a repeater, just want to configure a GMRS simplex channel on my radio with a privacy code. Was not sure if I use Tone, TSQL etc or what the values would be. Or if that is even possible with Chirp Quote Link to comment Share on other sites More sharing options...
