I am just going to set up now for some local tests on 500kHz JT9-2 to see if I can decode my own transmission. I could see PA0O, a strong signal but could not de-code it although others could. I set up another RX system and could not de-code my own signal and G6AVK could not de-code either. Whereas JT9-1 decodes locally and at G6AVK.

I do go through the change mode shutdown and re-start sequence. My first JT9-2 transmissions were JT9-1 for twice the time or so it appeared so no de-codes.

LF,

I'm now receiving in JT9-1 on 137.43 kHz. I can see a strong JT9-2 signal but there is no decode. The signal appears in the programs waterfal display. Timing is accurate. The SNR must be at least 15 dB above the decode level.

See this capture https://dl.dropbox.com/u/19882028/LF/JT9.png

Has someone an idea?
