Re-broadcasts
Every attempt is made to keep 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.

Broadcast Outages
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 to  . 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 in our Technical Reference Section

Call back sessions follow each transmission
