The solar radio noise is measured daily with amateur
theat means I use an old communication receiver AR3000 modified
for radio astronomy purposes. The detector is composed of an analoge
S042P (Siemens). The Yagi-antenna is a standard TV antennae
(BIV/V) for channel 37.
The antennae is
fixed in meridian,
but the elevation is tilted once or twice per month according
to the actual elevation of the suns orbit (Transit Meridian
The receiver is
via RS232 with a Windows compatible PC running under XP and Borland
Builder 6. This PC is also part of
the internal network, thus the data can be captured very easily. Every
month a graph and a listing will be produced and stored in the archive
During 2019, after 23 years of observation local radio interference (due to DVB-T and mobile phone activity)
went terribly strong and wide-band, such that solar flux observations went impossible. Observation of dynamic solar radio burst in continuing.
