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

Yes, something like that. After that test, we might try a marginal co-phase EbNaut transmission which would not have made it otherwise.

Unfortunately our weather has decided to turn wet and windy before Easter, so no transmissions from this corner today.

All the best,

Just goes to show that, although it's hard to radiated
more than a few uW at VLF, a little power goes a long
way at those frequencies.

Perhaps it encourages others to have a go.

Understood. I expected that. No matter, the 150 degree
difference is the important number if you want to try
coherently adding your signal to Stefan's.

How will we know if it is working? I guess you both would
transmit carrier, and you would reverse your phase say,
every hour. Then I should see +/- 2dB amplitude change.
