Some of my experiences with installing a (2nd hand) Dreambox DM500 HD (v1);
It's setup to receive Astra 2 E/F/G at 28.2° East. I did not connect an external harddisc. Instead I record via NFS.
The dish is a Triax TDS 64cm and the LNB an Inverto IDLH-SNL410-HMPRO-OPN Home Pro Single 40mm PLL LNB. The coax cable is Hirschmann Koka 9. Which is a foamed-PE, triple shielded coax. I use regular screw-on F-connectors.
For this you need to;
There are various sites which do the calculation for you.
This is one of them;
Satellite finder with magnetic north, azimuth & elevation calculator
The back wall of my house runs almost in a perfect east-west line. Almost but not quite. I tried to measure the angle in three different ways;
These yielded angles of 4, 9 and 7.5 degrees.
My initial impression was, that the Google satellite view based angle was the most accurate. So I used a box-cutter, a felt-tipped pen, a measuring tape, a ruler and a bit of trigonometry to create a large carton board triangle. I put one side against the wall and used a compass to check the direction of the hypotenuse, which now should point at the satellite. According to the compass, Google was a bit off. So I modified the triangle to match the city plan instead.
---------------- Wall \ | \ | \ | \ | \| . . . satellite
Next I aligned the dish with the hypotenuse and then slightly turned the dish to obtain maximum SNR. As it turned out, the current direction is a close approximation of the Google satellite view. So a Google satellite view can in fact be used to align a satellite dish.
According to the manual, the arrow-left and arrow-right button can be used to delete characters during text input. This does not always work. When this happens, use the mute button instead.
When editing a file doesn't work or returns to it's original contents after a reboot, do:
On my LAN the Dreambox is called 'dreambox.int.sput.nl' and has a fixed IP address. The NFS server is called 'sput.int.sput.nl' and has IP address '192.168.1.1'.
'/data/dbox/' is the exported directory. The Dreambox recordings are kept in
'/data/dbox/movie/' (edit / change to suit your needs).
After editing the file do;
NB: This is on a non-systemd system.
auto.network:sput -fstype=nfs,rw,nolock,soft,timeo=10,rsize=4096,wsize=4096 192.168.1.1:/data/dbox
'sput' is the directory in '/media/net/' where the NFS volume is mounted.
You need to create this directory first (edit / change to suit your needs).
After editing the file do;
During the day the BBC 4 data-stream contains CBeebies. Which has a service-id
which is different from BBC 4. Which in turn confuses the Dreambox a lot.
The Dreambox has the tendency to reboot after recording BBC 4. I'm not quite
sure if this a bug or a feature.
To 'fix' this, I record a bit from an other channel some time after the BBC 4 recording has finished.
Alternatively one can use a cronjob to switch to an other channel;
#!/bin/bash wget -q -O - "http://dreambox.int.sput.nl/web/zap?sRef=1:0:1:2876:800:2:11A0000:0:0:0:"
The above cronjob runs at 4:15 and switches to BBC News.
