ZL6QH 137.7888 kHz BEACON TEST ON 17 AUGUST
ZL6QH will be carrying out beacon tests on Saturday 17 August, starting
before ZL6QH sunset and going till after ZL6QH sunrise. Hours of local
darkness for ZL6QH are from nominally 0536 UTC (sunset) to 1912 UTC
(sunrise).
Dual frequency keying will be used, with 0.4 Hz frequency shift. The coding
is for an ID character of Q, sent as hi, hi, lo, hi, key up.
hi = 137.7890 kHz
lo = 137.7886 kHz
Each element is 120 seconds (dot length) so sending each Q takes 10 minutes.
Each Q will start on the hour, and each following Q will keep close to a 10
minute cycle within the hour, which could be useful for analysing results
during a brief propagation lift.
Listening out with a receiver carefully set to 137.7888 kHz centre frequency
and using Argo software to process demodulated audio fed to a PC sound card
is the recommended way to try for DX reception.
Reception reports can be emailed to [email protected] or posted to the
reflector.
Good luck to all listeners.
73, Bob ZL2CA
