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. > the phase is reproducable, it still is not absolute > as I have not attempted to calibrate the near-field > pickup probe. 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. -- Paul Nicholson --
