Intro

    The hf campaign ran:

  • 24jun20 through 26jun20
    • 24jun20 14:00 to 18:00 ast
    • 25jun30 13:00 to 17:00 ast
    • 26jun20 13:00 to 17:00 ast

    The campaign used:

  • The 5 MHz dipoles rcp for the entire run.
    • The frequency was set to 5.1 MHz.
  • The cycling of the  hf on,off was done with the keysight signal generators under program control
    • all experiments were synchronized to the hardware 1 second tick
    • all experiments started on the hour
    • The generators have  a delay from hardware tick to first state change.
    • On weds the delay was 100 usecs
    • for thurs, friday the delay was 1 millisecond
  • the 430 xmiter  was not used.
