Re: VLF: Carrier on 6470.005 Hz - and 6469.9975 Hz

Thanks Paul! Yes I intend to leave it on for a while.

I wonder if you could measure the relative phase of Stefan's and my daytime carriers? Although the frequencies are different, the phases are referenced to a common timeframe (midnight UT). We have been discussing whether we could transit simultaneously on the same QRG with appropriately aligned TX phase, increasing the combined signal by ~2 dB.

73, Markus

Looks to be about 0.06 fT here, but not significant against the
noise floor in one hour integration. If you can run for 3 hours
it could show up well.

For comparison, Stefan's (nighttime) 6470 signal is about 0.18 fT.
