The Radio Waves are Humming!

Lots of activity on the bands as intercepted here in Melbourne now as we move into our pre-winter period! Solar activity still low, 10.7 cm flux down to 114, equivalent daily SSN 65.
Radio Australia has opened up several changes in late April/early May to its A12 schedule, and these new channels have appeared, carrying English programming, all from Shepparton, and audible here via groundwave :
5940 1500-1700
7410 0700-0900
9890 1300-1500
19000 0100-0300 (interesting  usage in 15 metre band!)
21740 2200-0100
I haven't noticed any of the planned DRM transmissions.
It's useful to be remember that frequency management, transmitter operations, transmitter maintenance, transmitter construction, HFCC/ABU-HF frequency coordination (on-shore and off-shore), are the responsibility of the transmission provider Broadcast Australia, which owns all ABC transmitter facilities, leasing these to the ABC, with funding provided to the ABC by the Federal Government's Annual Appropriation Bill.
