We are trying to coordinate the suggested frequencies in WSJT-X with updated band plans being considered by IARU, ARRL, and other amateur radio societies. Why would I want to operate FT8? It's a popular mode, so popular in fact that one report citing Club Log data recently showed that 80% of HF contacts in their tracking nowadays are FT8. Darkness for night shadow (0-1) Show all Show LoTW/eQSL Show LoTW Show eSQL. Wondering if I can get some clarification. On a trial basis, and in response to numerous suggestions from around the world, we have added a second set of suggested dial frequencies for FT8 on three HF bands and also on 6 meters. This includes: harm to minors, violence or threats, harassment or privacy invasion, impersonation or misrepresentation, fraud or phishing. You can make contacts a lot faster on CW or SSB.

Most times the 599, is abbreviated as 5NN for CW only as it is much shorter to send then the actual two nines when using code. Your transmit and receive capabilities are not that much different. When you get back a signal report from someone, it just tells you how loud you were on their setup at that particular time. As we know, we have a maximum of 8 tones (modulation type is FSK-8). Grayed-out cells are commonly-used frequencies which are not included in the default program settings of JS8Call or WSJT-X (FT8). It will gain acceptance in SOTA too.
