Last year I posted a questioned about which had the better ability decode (In Level /sensitivity), was it CW, FT8 or JS8CALL (JS8CALL This is the same as FT8 just with messaging capabilities).
I received a ton of math, and theories...
If you go by with VOACAP (Voice of America Coverage Analysis Program) the answer is FT8 (And JS8CALL / Messaging), which indicates it requires less power to close the link. On Side note FT4 is basically the same as CW.
And if you like a QSO with FT8 sensitivity, well, JS8CALL is your answer.
I am fan of CW... Practicing every day, (I passed the 20WPM back in 1980!) But technology moves on!
CU on the bands...

| Loaded up JS8Call over the weekend, I really enjoy making contracts were I actually communicate with other operators. Much more fun than FT8 | ||

| I just started using FT8 and FT4... To me both are a mindless mode of operation, all you do is click the mouse.. the PC does the rest. I guess if all one wants to do is make contacts for the log it is great for that and for wall paper. I still like CW better..at least you do have to use your brain to copy and you get to know the other person a little. I though these digital modes was for low power but I see signals 20-30DB over nine. much stronger than CW or even SSB signals.. I guess their will always be those who have to use more power...3-5KW is the norm anymore.. I guess I'm just getting to old to keep up.. and for that I'm glad! Bob W5RG 65 yrs of Ham Radio.. | ||

| K0UA...Thanks for that.Info, especially the "Short" interval about FT4...(When compared to FT8), it make plenty of sense. Reply to a comment by : K0UA on 2020-02-18 While FT8 will go deeper into the noise than FT4, however. Propagation is NOT static. In other words the path from A to B is constantly changing by several dB . Often within a few seconds. Sometimes FT4 will make and finish a QSO where FT8 won't because FT8 takes too long. Same problem that JT65 had and why FT8 was created. FT8 is so much better than JT65 when JT65 is several dB better at going into the noise than FT8. But time is everything. The shorter the better. | ||

| I passed the old Advanced with 13 WPM. Good for you on the 20 WPM Extra. 73 | ||
