Hi,
I just often think about how to make a call sign visibility in the time of operation. So, when I connect in the specific frequency and listen a call sign there will be easier to read this call sign on a transceiver screen. Probably, there need to be incorporated on different frequency a voice recognition module.
Please let know if this kind of improvement possible to do for HF bands without any digital modes.
