Hello Rik/OR7T
Thank you for the qso. Copied you without errors after correcting my rx frequency.
I left the shack unattended now but rx is still on dial 474 kHz usb with picture grabber active

Maybe some operator want to leave some words.

All the best

Hello Group,
Thanks Wolf for sharing this info.
IW4DXW and me (qrb abt 600 km) are now in qso testing this program on MF dial 474.000 kHz.
Speed 1 baud seems very confortable.
We are looking to contact other friends.
73, Domenico IZ7SLZ

Greetings all,

I received the following info from Murray, ZL1BPU, who asked me to forward this to the group since his messages don't seem to get through.

73 and GL,

New Digital Mode for LF/MF

Three years ago ZL2AFP introduced a weak-signal QSO mode specifically for the LF/MF bands. The mode has now been
updated and enhanced, and is capable of comfortable QSOs at down to -25 dB SNR, so almost as sensitive as WSPR.

However, the new WSQCall V1.00 is a QSO mode, and also has selective calling capability, plus automated responses
and the ability to send and receive files. The protocol is the same as for FSQCall, so should be familiar to
existing users.

The WSQCall signal is just 50 Hz wide, is easy to tune, and experience has shown that it will fit between carrier
QRM lines on 630 metres. What's more, WSQCall V1.00 also has three notch filters available to knock out carriers.
These notches are adjustable in frequency, width and depth.

Operating at only 0.5 baud, WSQCall achieves a respectable 5 WPM through the use of a special alphabet and very
efficient character coding. This is a true real-time QSO mode with no timing restrictions, not just a beacon.

We have been using this new version for reliable 300 km 630 m contacts DURING THE DAY, and the range at night
should exceed 1000 km.

You can now read an introduction and download the software for WSQCall V1.00 from:
