Hello Paul.

If your USB dial is 474.2 and BW around 500Hz, you copy only signals between 475.450 and 475.950.

The WSPR2 window is 475.600 to 475800, and you are inside it.

I noticed that usually the JT9 transmissions are between 475.200 and 475.600 and with 500Hz BW you lost a part of the window.

Here for JT9 I use 474.2 USB dial but a 1000 Hz minimum BW to have a full copy into the JT9 window.

Also, it needs to be patient because the efficiency of JT9 decode is not as good ad the WSPR2 and the level of activity on JT9 is erratic : at rare moments it is high, but low most of the time. IT is necessary to have a look at the pskreporter map to get an idea about the activity on band before go and listen JT9.

73 de Andy.

Hi Markus,

I've tried 'dial' 474.2 USB too,BW around 500Hz, last night but had no decodes in JT9,
then changed to WSPR and got plenty of spots.
I was using WJST-X v1.6.0 .
Obviously I am missing something but don't know what.

Here's last night's RX log from Nuremberg. Using 474.2 kHz LO,
I had initially been monitoring 1300+-100 Hz only. Around
20:50 I noticed some activity left of the receive range
indicator and extended the tolerance to 1180+-200 Hz.

Best 73,
Markus (DF6NM)
