VO1NA on 8270.00709 is a good nighttime signal at Todmorden recently. Here are the last three night's spectra in 34.72 uHz (8 hours 23:00 to 07:00 UT) using combined E-field and H-field. http://abeli
Paul Markus and Group, Thanks Paul for the reports. The radiation gives more gratification than the efforts to get a stable carrier. Great result! Truly astounding that Paul can receive 10 uW at 3600
Joe, Did you try the "[0] Interpolated PPS signal" option? ("Sampling Rate Detector" window, "Scope Option" drop-down menu) 73, Jim AA5BW Paul Markus and Group, Thanks Paul for the reports. The radia
Hi Jim, This looks like a sin(x)/x curve centred and peaked (y=0.1) at t=0 and 0 crossings at t= +- 60 uS; sd=300 nS. Thanks & 73 Joe Joe, Did you try the "[0] Interpolated PPS signal" option? ("Samp
Hi Joe, VLF, Same problem at RC4HAA. They put their grabber online at http://136.su/grabber/ and granted remote acces to their PC. The PPS looks like in the attachment. Looks like a C is shorting the
If you choose to use the NEO7 fractional pll output directly, then pick frequencies which are 48MHz/N where N is an integer. This will lead to a much cleaner signal. 8.27015kHz is one possibility (48

Hello VLF, Thanks to all for the helpful suggesions and discussion. Your's truly has been taking lots of notes and tinkering with limited satisfaction. There has been no luck trying to communicate wi
