TRANS-PACIFIC LF TEST SCHEDULE 6 June 2000
Arrangements have been made for a number of West Coast stateside LF
listeners to
find out what they can receive from ZL LF test transmissions. The
timing is
Saturday night 17 June (New Zealand time) which is Friday night and
Saturday
morning California time. It is intended to also try again on Saturday
24 June,
but subject to review, depending on what is reported for 17 June. The
following
table shows the respective sunset and sunrise times:
ZL sunset CA sunrise ZL sunrise
========= ========== ==========
17 June 0455 UTC 1252 UTC 1950 UTC
24 June 0457 1253 1952
The timing happens to be around the longest day (mid summer) in the
northern
hemisphere, which of course corresponds to the longest night in the
southern
hemisphere (mid winter).
The following stations intend to be transmitting:
ZL1WB 181.42 kHz
ZL6QH 182.10 kHz (operated by ZL2BBJ and ZL2CA)
ZL3PN 182.70 kHz
ZL4MD 183.50 kHz
ZL3VN 184.00 kHz
ZL3JE 184.50 kHz
ZL4OL 185.00 kHz
AX2TAR 176.50 kHz (VK7ZAL, Tasmania, Australia)
The station with highest radiated power is likely to be the Quartz Hill
station
ZL6QH. It is intended to run ZL6QH as a continuous beacon transmission,
from
around 0400 - 2000 UTC on 17 June. This covers times for many "dark"
paths, both
east and west.
AX2TAR is also planning to run continuously, from 0630 - 1300 UTC on 17
June.
All other stations will definitely try to be transmitting for around
half an hour
either side of ZL sunset time as well as the California sunrise time.
As each
station has a unique test frequency, there is no co-channel pile-up.
Frequencies
have already been checked for not coinciding with local QRM for
receiving stations
in California.
In general, stations will attempt to maintain their assigned carrier
frequency
within 10 Hz. In general emissions will be conventional CW at around 5
wpm.
Reception reports are welcomed. Email to reflector sites would
generally be the
fastest and most effective way to disseminate reports.
