A few clicks of a mouse and you have made a QSO, automatically uploaded to a logbook on the web, probably including some form of QSLing. Everything has been hashed out already and is presented on a silver platter. Whatever you use for the JT-modes, it’s basically like a smart phone app. Thus JT65 is your best choice, Olivia clearly not. If your language and typing skills are sub-par then you rather not engage in more than a basic exchange. Part of it is lack of proper English education and part of it is saving face. Speaking English is most awkward for many Chinese, Japanese and Korean. Living in Asia I know that many hams here are intimidated by English. QSOs in Olivia can take an hour or more, because you can write whatever you like and engage in real conversation. With JT65 you don’t even have the possibility to go deeper than 599-73, because it’s all that you can do with it. The complaint about PSK31 was that is was mostly used for 599-73 macro QSOs. I think many people either don’t want to, are too lazy to, or forgot how to talk in a meaningful way. That written content is often not very extensive or deep: simply short bursts of information and often even in code like geek speak or emojies. However, 99% of its use is for written communication, not for voice. The smart phone has taken over as our main means of communication. So why is JT65 king and Olivia not? Here is my list: Like the JT-modes all based on MFSK and even deep in the noise you can still use them for meaningful communication over long distance. But frankly, I think there is more to it.īecause, apart from JT65 there are many other modes that work well under difficult conditions. Steve lists the usual reasons often cited for its popularity: the waning sun, increased urban spectrum noise, working DX contacts at very low power levels and with modest antennas, no-code hams etc. Even psk31 signals hard to find, while the JT65 slice is overflowing with signals, often S9 plus many dBs in strength. Like Steve I’ve also noticed rather empty CW and SSB portions of the band. Recent articles here on by VE7SL on digital modes made me ponder about why JT65 is so popular nowadays.
