Once every two months. I receive QSL cards from domestic and foreign stations from QSL Bureau. Recently, I often QSO in digital mode. The QSO in digital mode, the report exchanged is SNR, not RST. However, most QSL cards have a number without a unit in the "RST" field, such as "-14".

How do you describe it in your own QSL?

I may care too much, but I try to include the report with "SNR (dB)" instead of "RST".

I am adjusting the format. But I think it would be OK to correct the handwriting such as SNR instead of RST, and add units to the numbers shown.
