Hi, 500 Hz is chosen by default in VarAC and it is impossible to change, impossible to choose 2300 Hz. Do you know why ? Thanks
Thanks for the answer.
2300 Hz is only to transmit files on VARA FM.
The message is quite clear noting that it is not allowed to use 2300 on Calling frequencies.
You can use 2300 on any other frequency but please refrain from doing this on the slot system frequencies range to avoid QRM on other QSOs.
Use it away from the slot system please.
