Hello Chris,
I see you are strong again on LF. I started my JT9 RX here on LF.
However the QRN rised extremely since the afternoon.
The latest versions only support JT9-1. This was successfully used by
several stations on MF some months ago. 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. If your U3S does not support JT9-1, maybe there are firmware
updates?
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

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!
