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

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
