DVB-T2 in South Africa - a year later

It is a year since I started to have a look at the digital TV transmissions in Stellenbosch. Initially I used a PCTV Systems DVB-T2 290e to receive the transmissions on my computer under the Linux operating system.

Reggio di Calabria, Italy

Currently I am visiting Reggio di Calabria in the south of Italy for three months. It is for an exchange program the university here has with the University of Stellenbosch.

Some of the photo's I take will be uploaded to the following two web albums.

SDR with Raspberry Pi and DVB-T receivers

My holiday project is to play around with a Raspberry Pi and a RTL-2832U DVB-T USB receiver. This specific receiver has a mode where it dumps raw IQ samples over USB to the computer. The gnuradio experimenters realised this and therefore gnuradio supports this relatively cheap off the shelf USB receiver as a software defined radio.

The Raspberry Pi has a rather tiny ARMv6 CPU running at 800MHz. Doing signal processing on this CPU (as the GPU is still too closed to do it on that), looked impossible to me.


Dis Stellenbosch. Dit raak somer. Warm nagte lê voor en het eintlik al reeds begin. Dis nie 'n slegte gevoel om lekker warm te gaan slaap na die lang wintermaande nie. Maar o wee! Saam met die warmte en slote vol water om ons heen, is daar 'n pes aan die broei in die dorp. Dis weer muskiettyd.

Gisteraand net voor ek gaan slaap sien ek hierdie teen my kamermuur:

Die eerste muskiet van die seisoen het dit gewaag om in my kamer in te klim!
