Jacques, it's in the notes for firmware 3.84 :-


"* SQUELCH-CONTROLLED 1750-HZ PL TONE: Some EU

repeaters require a 1750-Hz PL tone burst to open. Previously, an

0.5-second burst was generated at the start of each transmission.

Now, this tone is only generated if squelch is not already open.

The squelch-controlled PL tone feature can be turned off by

setting the PITCH parameter to PL OFF. With either the PL TONE

or PL OFF setting, the operator can still do manual PL tone

burst as described in the next item.



* MANUALLY CONTROLLED 1750-HZ PL TONE:

The operator can now generate a variable-length tone burst

at any time while transmitting by holding PITCH switch."



73 to all
