ZM2E will be conducting transmisions on 137 kHz at Quartz Hill from 31 March to 2 April 2007.
The transmissions will be 0.2 Hz frequency shift (137776/137776.2) and with dot length to suit conditions. A beacon strategy has been agreed between participating stations: ZM2E will beacon with Z at FSK120 starting at 15 and 45 minutes past an hour, and other participants (all on unique frequency slots) will also beacon with FSK120 from the hour and half hour (see table for beacon ID short call sign). If beaconing shows a path opens, then a QSO attempt will commence, in which case the beacon sequence lapses. Dot length during QSO mode will be selected by each station, for what they think suits conditions, so there can be no advance notice of how third parties can best sticky beak on a QSO attempt. At ZM2E we will have several PCs and run a range of Argo dot length displays, so we can handle anything that comes our way.
If ZM2E is not in QSO mode within an hour or so of Quartz Hill sunrise, then to facilitate possible reception reports from EU we will go to continuous beacon mode, sending ZZZ. at FSK120, and with timing of each Z starting on the hour and ten minute rests thereafter.
There is a bed and mattress firm in Wellington with a slogan: "You get more Zeds at Wellington beds". How that compares with ZM2E can be checked out from any listener reports. We would hope that you get more Zeds from Quartz Hill, but the last laugh may be on us with the threat of watching eyelids during the third night.
There is no internet access at the remotely located Quartz Hill station, but we will likely travel to town during daylight hours to check email.
Here is a list of the particpating stations over the period 31 March to 2 April 2007:
