Re: [HCDX] Radio Australia DRM 5995 kHz

["Craig Seager" <shango@xxxxxxxxxxxxxxxxxx>]

Earlier in the week, Nigel Holmes at RA told me that 5995 kHz uses DRM
1200-1400 UT on 010 deg to PNG and 12080 is DRM 1100-1200 UT on 080 deg
(into SW Pacific). Both from tx's at Brandon. Nominal power is 8 kW but
did want to run as low as 2-3kW.

The relatively low power (and the beam headings) might explain the poor
results.  I can't get anything useful on 12080, and 5995 only produces
occasional snatches of audio.  The high bitrate (23.54kbps) no doubt
doesn't help.

Nothing here on 1431 or 1701 either (central west of New South Wales).
Can't even hear DRM hash on 1431; 1701 seems to register something in
Dream periodically, but not enough for any on-screen information &
definitely no audio yet.

Craig Seager, Bathurst (Icom R75, Dream software)
