![]() ![]() ![]() Like Steve I’ve also noticed rather empty CW and SSB portions of the band. JT65 FLDIGI PLUSĮven psk31 signals hard to find, while the JT65 slice is overflowing with signals, often S9 plus many dBs in strength. 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. But frankly, I think there is more to it.īecause, apart from JT65 there are many other modes that work well under difficult conditions. 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. ![]() The smart phone has taken over as our main means of communication. However, 99% of its use is for written communication, not for voice. 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. I think many people either don’t want to, are too lazy to, or forgot how to talk in a meaningful way. The complaint about PSK31 was that is was mostly used for 599-73 macro QSOs. 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. QSOs in Olivia can take an hour or more, because you can write whatever you like and engage in real conversation. Living in Asia I know that many hams here are intimidated by English. Speaking English is most awkward for many Chinese, Japanese and Korean. Part of it is lack of proper English education and part of it is saving face. If your language and typing skills are sub-par then you rather not engage in more than a basic exchange. Thus JT65 is your best choice, Olivia clearly not. Whatever you use for the JT-modes, it’s basically like a smart phone app. Everything has been hashed out already and is presented on a silver platter. 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. Compare that to Fldigi (the Swiss army knife of digital modes) where you have to find the right frequency, choose the right mode, zero in on the signal and only then you can start playing. JT65 FLDIGI SOFTWAREįor ease of use JT65 software is the master, Fldigi the not so convenient Jack-of-all-Trades. Standards are a great thing and hard to come by. You can use JT-modes on any frequency, but there are designated meeting grounds if you are looking for a QSO. Added bonus is that on HF you monitor a 2 kHz wide portion of the spectrum, so you can quickly find the most interesting stations. Olivia has designated frequencies, too, but they are not set in stone, thus you are less likely to meet someone on air. FLdigi doesn’t guide you to a set frequency, that task is up to you. ![]()
