Hi Eddie

 

I have a trace of your QRSS using DM780 on 503.218.  

 

Time 10.25z

 

My locator is IO92ub.  

 

Rx. IC706mk2g 

Ant Inverted L 7m vertical/28m top hat radial, fed via 400uH tapped coil and impedance txfrmr

 

On the DM780 trace you are showing as faintish yellow line but steady and visible

 

This is of course assuming you were/are Txing at this time!  

 

 

 

 

With best regards

 

 

Jim

Hi, Eddie.

 

I'll put the proper "tee" antenna on this morning - it should improve reception.

Hi Dave

 

Thanks for the Grab, yes that looks pretty promising, a little noisy for accurate confirmation but 17.50 is the time when I changed back to the WSPR MEPT and went for dinner.

 

I will give it another run in the morning. I am still calculating the ERP is only around 200mW .

Well, Eddie,

 

I think I saw something.... it stopped at about 1750 utc. Only using a miniwhip here at the moment, so receive performance isn't great on 500 kHz.
