For LF, a frequency below 137.45 should be used, to avoid collisions with OP32, WSPR and EbNaut transmitters. So just try *137.4 kHz*. I'm watching there for you now.

Listening stations and contacts are also listed at https://www.pskreporter.info/pskmap.html, select the JT9 mode at 2200m to filter the list... 73, Stefan Am 14.06.2017 18:01, schrieb Chris Wilson: > Hello DK7FC, > > I have never tried JT9, but it appears my U3S exciter covers that > mode.

Hello DK7FC,

I have never tried JT9, but it appears my U3S exciter covers that
mode. What time span (there's JT9-2 upwards it seems), and what
frequency is appropriate? I am happy to give it a shot!
