[chirp_users] Settings to match Motorola PL tones

[Rich Messeder]

I think this is a good question. I have recently acquired 2 BaoFeng UV-5RTP. I have programmed them "successfully", but not tested the results.

Here is my take on it.

I think that CHIRP allows the user to select TSQL, indicating that the ToneSql value is used for repeater access. It is unfortunate that we all don't use the same terms. I opine that CTCSS is the same thing as PL; one is a generic term and the other a vendor term.

I understand that Tone in CHIRP is used for receive. If you have Tone selected, then the sender must use the agreed tone to open your squelch. For repeaters, I am not sure that all repeaters use tone (PL, CTCSS) on transmit, as they do on receive. A repeater first senses the carrier on the inbound freq, and then look for the PL tone.

My impression is that many radios do not (can not) use PL codes /from/ a repeater that are different from the sending PL tone.

Now to 2 radios.
The sending unit must send the same tone that the receiving unit is filtering on. So if you are both working simplex, and you both have tone squelch enabled and are using the same PL|CTCSS tones, it should work. I might try that later today or tomorrow if I have the time.

Tone
This sets the CTCSS tone to be transmitted if the Tone Mode is set to Tone. In Cross mode, it has additional meanings (see description of Cross Mode for more details).

ToneSql
This sets the CTCSS tone to be transmitted and used for receiver squelch if the Tone Mode is set to TSQL. In Cross mode it has additional meanings (see description of Cross Mode for more details).

I too have used TSQL for many entries, and now wonder if I should be using Tone, because I want to trigger the repeater with a PL tone, but then want the reply no matter what.
