Dear LF, inspired by the very fruitful narrowband weak-signal detections on VLF, I have set up a temporary LF spectrogram, using Rubidium locked oscillators and a 0.438 mHz FFT bandwidth http://www.a
Markus, Excellent ! I can provide a GPS locked signal at any power level, my limitation at the moment is the keyer which only goes to QRSS60 - I may have to investigate another way of keying the TX.
Hi Warren, Jay, LF, after the nice "burn in" with Chris, I'll leave the RX on at least over the weekend, with display slots centered on 137780.30 and 137775.00. We're much looking forward for any int
Hi Chris, yes, there were good and narrow traces on both grabbers throughout the dark period, confirming the stability of a long skywave path. In Haifa, the upward Doppler shift around sunrise was cl
Markus, LF, As a newcomer to LF I find this as an interesting experiment for real low power or long distance tests for those who can achieve the necessary frequency stability requirements. I found th
Markus, Appreciate the test, your 100mW sure is QRO for this mode :-) How low can you go? Conditions earlier when you and Stefan transmitted in QRSS60 were at lest 10db worse than yesterday, there
