Long time no see... Stefan is back on LF! The WSPR transmissions are curren=
tly producing nice sky-blue traces on my grabber .

Best 73,
Markus (DF6NM)

Betreff: LF: JT9 on LF


Hello Chris,=20

 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 seve=
ral 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 j=
ust try 137.4 kHz. I'm watching there for you now. If your U3S does not sup=
port 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!
