The wireless time-signal sent from the Observatory have [sic] been received by many ships at considerable distances from New Zealand. The signals are transmitted by the Wellington Radio-station…on a wavelength of 600 metres, and are Telefunken quenched-spark signals. The type of signal sent from the Observatory consists of long dashes of about one second duration, and it is probably due to this long dash that the signal reaches so far. The longest distance reported to the Observatory was 4320 miles, for the wireless-telegraph time-signal received by the SS Tainui. The SS Waimana reported the reception of the time signal at a distance of 3638 miles.
