Hi Paul, About JT9 coding: for this I am using another exe file of the WSJT-X suite. It seems to work fine, both for free and structured messages. 73, Rik ON7YD - OR7T Hello Rik, I am very interested

Hi Rik, I do not know the symbol lengths for JT9 slow and I do not know how it compares to WSPR about frequency stability requirements. gets across the pond when WSPR2 cannot. Clearly for WSPR mode,

Hello Paul, I cannot find the WSPR15 specs right away, but I assume that is is just a "stretched" version of WSPR(2). In that case it would be 4-FSK at 0.195 Bd and a tone spacing of 0.195 Hz (0.8 Hz

Hello Rik, It has been a long time since I read the official WSPR-15 protocol specification but your description sounds correct. I do remember it is 0.8 Hz bandwidth. Today I finally had time to inst

Hi Paul, all, "I don't know if it is possible to run two instances of SlowJT9 with different settings?" Your question triggered an idea: it should be possible (and even not very difficult) to decode

Hi Rik, all, That brings up some interesting possibilities! If SlowJT9 could decode all three modes simultaneously, then we could have some "beacon" stations alternately transmitting JT9-1, JT9-2, an

Hi Rik, all, I let SlowJT9 monitor MF JT9-2 until 0030z. Having not seen any JT9-2 signals I then changed the mode to JT9-1 to see if it was working. Right away I started getting the expected decodes
