When the audio is over-driven, that signal can take up many times more bandwidth than a properly modulated FT8 signal. Signal reports in FT8 are signal to noise ratio, NOT strength. FT8 is Weak Signal Mode FT8 80m Log. Dumb question: if you get back a signal report of, say, +12, are you likely to be splattering or overdriving? So, its interesting to see the future evolution of the ham radio digital modes. FT8 transmits and receives only the bare essentials needed to make an amateur radio contact (QSO): Exhange of callsigns, readability report, signal strength report, and "best regards" ("73"). So, the signal reports dont make any sense. Press question mark to learn the rest of the keyboard shortcuts. I am running a full 100W into my radio.

Different colors are different bands and minutes indicate the last time they heard and reported back automatically. JS8Call turns FT8 into a "chat" mode, allowing stations . Without further information all it says is the other person has a good SNR with your signal. JS8Call is an experiment to test the feasibility of a digital mode with the robustness of FT8, combined with a messaging and network protocol layer for weak signal communication on HF, using a keyboard messaging style interface. First number is for Readability (R), the second is for Strength (S), and the last one is for Tone (T) when representing CW signals. The idea of replacing characters with indexes is important here, which is effective when using a small dictionary size. The one on the right, being about 100Hz wide, is a second harmonic, and the one on the left, being about 150Hz wide, may be a third harmonic.

Re: [CQ-Contest] Reciprocity in signal strength I think this violates the Terms of Service. The message length of 77 bits was chosen as a compromise between the transmission time (about 13 seconds, which is not so fast) and the information capacity the message could be made longer, but the transmit time should also be increased. All this, combined together, made FT8 so popular. A 14-bit CRC will also be added. Could a strong signal lower the gain so much that the weaker signal no longer decodes? SNR measurements in this range imply the received signal power level is below the received noise floor. If you're getting a +5 SNR report then obviously dial it way back but when I do DX at 100 Watts it's usually -10 or less. signal reports when using FT8 and JT65.
