The first transmission was completed at 0032 and the last (19th) at 1025. There was a delay of 82 s between transmissions. The carrier was generated by an AD9851 synthesiser clocked by an Oscilloquartz 8663 10 MHz DOCXO which was purchased from "Zhou" in Hong Kong for less than what a bottle of cheap Scotch would cost, and calibrated against WWV on 10 MHz. An Arduino Uno programmed the 9851 to generate a carrier on 137.555 x 16 kHz and its output was divided by 16 by a cmos 4020 to improve the resolution and frequency accuracy. The Uno also keyed the carrier according to the op32 code that was copied directly from an email from DF6NM. The keyed carrier, a messy 3v p/p square wave, drove 2/3 modules of a Decca amp running at 60 volts 12 amps to yield 3-1/2 amps of RF which was coupled via 1.6mH of 2mm Litz to a 100m wire at about 12m average height. The relative signal strengths are useful and I hope to take advantage of this to compare antennas. Our local sunrise/set times today are 0734/2332. The summer solstice TA path may have opened before 0000 utc and had lasted until at least 0546. I'll give another try again tonight starting 2300 utc. 73 & tnx agn!
