IDENTIFICATION:
Repeater signs W6WGZ/R
every eight
minutes and two minutes after the last transmission
of a QSO. It waits until the end of a transmission
before identifying unless the transmission lasts
longer than two minutes. If the repeater is in TONE
MODE a short tone
burst follows call
identification.
TIME OUT: The
timer allows five minutes
followed by a
group of two tones, then a group of one, two, three or four tones. This
whole sequence is repeated several times.
Third group
One tone: A.C.
