Hi Gary

 

ROS seems intent on crashing at the same point. I have a screen grab ready for Jose if needed.

 

I will see if I can post a section. Showing -31dB to -35dB, dear Mal would need good ears.

Hi Eddie,

 

Thanks for your report, ROS is doing the work it was intended for ie. Weak signal use. In your case not even detected by other means.

 

Try again for a complete frame.

HI Gary

 

I am delighted to report a very good copy of your ROS signal 18:58 UTC. I would have sent a copy if the program hadn’t have crashed just before the end with ‘subscript out of range‘, the first time I have had crashes with ROS soft.

 

The signal is undetectable at audio and invisible on Spectran yet would be 100% copy without the crash.  A very efficient use of 100Hz bandwidth, thanks to Jose.

 

Once again due to the local Panasonic Plasma TV I am having to use an un-tuned 40m Doublet as the antenna. This is the first time I have ever detected an Amateur signal on 136kHz.

Hi LF,

 

My ROS MF-1 beacon is transmitting now with 3 minute timer.

 

Frequency is 137.500 kHz (dial 136.500 kHz USB), reports & QSO attempts very welcome.

 

ERP about 50mW.
