§  80.98   Radiotelegraph testing procedures.

   Stations authorized to use telegraphy may conduct tests on any assigned
   frequency. Emissions must not cause harmful interference. When
   radiation is necessary the radiotelegraph testing procedure described
   in this paragraph must be followed:

   (a) The operator must not interfere with transmissions in progress.

   (b) The operator must transmit “IE” (two dots, space, one dot) on the
   test frequency as a warning that test emissions are about to be made.

   (c) If any station transmits “AS” (wait), testing must be suspended.
   When transmission of “IE” is resumed and no response is heard, the test
   may proceed.

   (d) Test signals composed of a series of “VVV” having a duration of not
   more than ten seconds, followed by the call sign of the testing station
   will be transmitted. The call sign must be sent clearly at a speed of
   approximately 10 words per minute. This test transmission must not be
   repeated until a period of at least one minute has elapsed.
