ZL6QH will transmit from 0500 - 1230 UTC, and ZL4OL 1045 - 1215 UTC (targeting sunrise time in VE7). The transmission format for ZL6QH is dual frequency keying, with 0.4 Hz shift, and "dot length" of 120 seconds. The identifier is Q, sent as "dah dah dit dah", with "dah" as 184.4001 kHz and "dit" as 184.3997 kHz. Dual frequency keying has equal length elements for "dit" and "dah", and only a brief transition between elements, to save time with very slow keying, so each Q in the ten minute repetitious sequence of QQQQQ. has the following format: Dah of 184.4001 kHz for 2 minutes, then a brief pause Dah of 184.4001 kHz for 2 minutes, then a brief pause Dit of 184.3997 kHz for 2 minutes, then a brief pause Dah of 184.4001 kHz for 2 minutes A silent period of 2 minutes Repeated for the whole session The transmission format for ZL4OL is single frequency keying, with 184.3999 kHz carrier, and 120 second "dot length". This is deliberately arranged to be "inbetween" the dual frequency keying of ZL6QH, and allows one correctly tuned Argo screen to be able to capture either signal. The identifier is O, sent as "dah dah dah", so each O in the 15 minute repetitious sequence of OOOOO. has the following format: Dah of 184.3999 kHz for 2 minutes Silent for 2 minutes Dah of 184.3999 kHz for 2 minutes Silent for 2 minutes Dah of 184.3999 kHz for 2 minutes Silent for 5 minutes Repeated for the whole session 73, Bob ZL2CA
