shown that this is not a real issue, but is mentioned here in case
anyone thinks there is a problem with their equipment.

up to date re-broadcast details, however, there may be occasions when
times and frequencies may vary.
Do you know of a re-broadcast not listed?
Amateur radio clubs and repeater operators are welcome to re-broadcast
the monthly RAOTC broadcast. If this is done on a regular basis, you
are encouraged to contact the RAOTC by email with the details, and it
will be listed here.
Every effort is made by around six or seven regular members to bring
listeners the monthly RAOTC Broadcast. From time to time, however, the
broadcast team is unable to fulfill the advertised schedule. In this
situation a notice will be posted here if an alternate relay station
cannot be found.
Current notice of proposed broadcast outage - None
Call for broadcast relay volunteers
If you feel you may be able to help to transmit the broadcast on a more
or less regular basis, from your location, then why not drop a note
One example would be to transmit the evening broadcast on HF on 80
metres, from a location in Brisbane, or the morning broadcast on 160
metres from a location in Sydney. With the current decline in solar
activity, every little bit helps. Another example would be to transmit
it over your local FM repeater, providing of course, that you have the
repeater owner's permission. The audio is supplied as an MP3 file and
is made available via email a few days before the broadcast date. In
order to provide a positive experience (as opposed to negative!),
kindly have a look at our Broadcast Technical Requirements.
