Sec.  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.
