Overnight DX on JT65A

The haul of JT65A stations heard overnight on 80m was quite impressive, although there is a gap in the middle of the night when the program seemed to stop decoding. I woke up around 4am and went to see what had been heard, and nothing was on the screen since before 2am so I stopped and restarted the program.

The number of different stations logged is far fewer than when I did a similar exercise using PSK31. But the proportion of US stations logged is much higher. The best DX - KE5ZGI in New Mexico, a distance of nearly 8,000km - is much farther than anything I have heard on 80m before. So this JT65A mode is very interesting if you just want to see how far you can get.

I'm receiving on 20m now, and hopefully later on I'll be able to find the time to attempt a few more JT65A contacts.

Hello Julian, very interesting. I think I will setup this program tonight and leave it on 80m. 73 Bas

Hello Julian, well done. What is your power with JT65A on 80 meter?

I think I was running 25W. I'm not sure what power most people run on that mode.
