Great result! Hmm I thought that VO1NA had been on 477 kHz during those nights. Joe are you transmitting MF and VLF simultaneously, on two antennas? Do you already have GPS lock available on 8.27 kHz? 73, Markus -----Ursprüngliche Mitteilung----- Von: Paul Nicholson <[email protected]> An: rsgb_lf_group <[email protected]> Verschickt: Sa, 7.

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://abelian.org/vlf/tmp/171007b.gif S/N 12.6 dB http://abelian.org/vlf/tmp/171007c.gif S/N 14.5 dB http://abelian.org/vlf/tmp/171007d.gif S/N 11.4 dB Not bad for 8uW ERP at range 3575 km and an undisciplined OCXO. -- Paul Nicholson -- |
