Emtec S830

s830 Inside, back

s830 Inside, front

A DVB-T USB Stick from Emtec.

It is currently not supported under Linux, though some experimental patches exist (see below ... in particular, the user experiences section).

Overview/Features

It features dual tuners, remote control, and 'diversity' tuning capabilities (not sure about the last). Evidently this device is a rebranded YUAN High-Tech Development Co., Ltd Product.

Its says PD-870 on the PCB though emtec sells it as S830, so clearly some rebranding is going on.

Components Used

• 2 x MT2266F (tuners)
• 2 x DiBcom7000PC1-AXXXa-G QGYN8 (demodulators)

A patch which adds the usbid for this device to required drivers is available here.

User Experiences

So far unsuccessful. After adding the usbid, as described in the patch above, the same results are obtained as the user in that original mailinglist post .... i.e. the led on the device goes on, the driver modules are loaded, but no lock on frequencies is obtained.

It should be behaving like a Pinnacle PCTV Dual DVB-T Diversity (PCTV 2000e USB), but attempting to tune to a frequency from a valid channels.conf file (obtained from a working DVB-T card) results in no lock being established:

$ tzap -a 3 -c /home/waldo/Desktop/channels.conf "een"
using '/dev/dvb/adapter3/frontend0' and '/dev/dvb/adapter3/demux0'
