Thread-topic: LF: Tx test QRSS-30 476.180
Hi MF

Thank you all for the try. But keep an eye aearching from time to time

I'll keep txing. No way to blow-up the electricity bill at QRPPPP ;-)

There is an spurious signal very clear on my MF Grabber centered on WSPR 
sub-band
It is just 400Hz down from the main signal but you can check the signal timing
https://www.dropbox.com/s/e3f1fuv1z7yxw2n/EA5DOM_MF_SLab_Grabber.jpg?dl=0

Every frame starts at 00-15-30 and 45 minute. There is time to GPS recalibrate 
the U3
which is a good feature to keep QRG. Not really a standard reference but quite 
good
and much better than a free running oscillator

Thank you for the link to the vertical loop André. Very interesting but hard to 
install
here. As Graham and others suggested, will try a top feed slopper against the 
building
But will be a winter project. Now it's time to attend the other end of 
spectrum: mW and nanoW

Hi Luis,

Good luck for your test! It is interesting!
Maybe it is not the best time in the year :-) Very strong QRN today due to 
local thunderstorms. Anyway my grabbers are running 24/7.
My frequency accuracy on MF is not so high, maybe +- 2 Hz. It is not locked to 
a reference signal and has xtal stability. I just did a 'calibration' by 
setting BIA to 474 kHz (eye accuracy)...
If your signal is accurate and appers on my grabber, i will calibrate my RX to 
your signal :-)

73, Stefan
