Hi Graham,

 

Thank you for your statement!

Well actually, especially Scattergram or equal measur= ement methods would be of interest regarding the aspect of signal path monitoring. (direct wave / sky wave via cross correlation of pulse delay values).

However, the aspect of interferences by using 500us p= ulses has to be taken into consideration but may be there are coming up suitable solution= by the LF-group.

Another method of monitoring the signal path on 500 k= Hz could possibly performed by using the “PSK Sounder” software from ZL2A= FP. And what I saw on a first glance it should be usable for transmission and reception in order to monitor the signal path situation.

 

By the way:

Do you know if Andy is continuing the Multi-function=20= beaconing on 503.7 kHz?

In this case I would try long term signal monitoring=20= by GB3RAL.exe and PSK message decoding within the next evening sessions.=

So far so good .. quite a step up in signal round=20= 2100 hrs 

no frequency decode before then , 15 db over noise= at 2130

 

but a trend showing

about  1 hour slow qsb

 

any other reports ?
