    within the following conventions, giving long distance communications and experimentation
    priority.
135.7 - 136.0 kHz   Station Tests and transatlantic reception window
  135.900-135.980 kHz preferred transatlantic window for Europe to North America
  transmissions of very slow telegraphy (QRSS)
