In the past, we typically used our subjective assessment of the other party's signal when receiving their signal. Now, let's assume I have established communication with B00IRU. I noticed that his signal was intermittent and contained background noise, but I could still understand what he was saying, likely due to the fact that we were communicating in Chinese. Therefore, I gave him a subjective rating of 54. Then, he reported that my signal was rated as 48, which was barely audible. My log entry reads:
| Date | Time | Frequency | Mode | Call sign | RST | Comments |
| 0521 | 0735z | 14.250 | SSB | B00IRU | 59 - 48 | IRU's 100th Anniversary from China |
(Refer to the ARRL Logbook Mini format)
Note: The two numbers for RST, the first one (59) is the one I sent, which means I definitely transmitted it according to the highest standard, so it's 59. The second number isThe other party provides feedback on my subjective rating.Here it is: 48.
So, the QSL card I sent to the other person was...

| VERIFYING CONTACT WITH | DAY | MONTH | YEAR | UTC | MHz | RST | MODE |
| B00IRU | 21 | May | 2025 | 0735 | 14.250 | 54 | SSB |
I hope this example will answer the original poster's questions.
