It does not use a receive PL tone, it will repeat any signal on Ch 18. It does however have a transmit PL tone of 67 Hz for use in radios where you can program just a receive PL tone to eliminate double repeats when your within range of another radio. It also utilizes Boafeng squelch tail elimination (STE) so if your using a Boafeng radio turn that feature on to stop all squelch tails. It has a 8.2 second record time to encourage timely conversation.
Because a simplex repeater with noise squelch will trash out any channel its on and the owner/operator is an idiot for putting it on the air with out a PL on the receiver.

Well it has been up for years without any ill effects (started back in 2016). It has never experiences any interference in it's current location. It does however get a little de-sensed from a near by repeater when it is transmitting. I played with PL tones in the beginning and found it wasn't needed and it actually reduced the range a little bit. As a matter of fact a lot of the repeaters around here have no PL tone on the receive. We don't have the R.F saturation that some larger cities have. Also it is for public use and a PL tone would effectively hide it from public use unless they knew about it. Most non-hams don't understand what a PL tone is. Trust me if it needed a PL tone I would have it there.
