Emtec S830
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.

Remote Control Support
The usb stick comes with an Irda Remote
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' tuning to 482000000 Hz video pid 0x1011, audio pid 0x1012 status 00 | signal fc25 | snr 0000 | ber 001fffff | unc 00000000 | status 01 | signal f1e4 | snr 0000 | ber 001fffff | unc 00000000 | status 01 | signal dfe9 | snr 0000 | ber 001fffff | unc 00000000 | status 01 | signal e1b9 | snr 0000 | ber 001fffff | unc 00000000 | status 00 | signal e9cd | snr 0000 | ber 001fffff | unc 00000000 | status 01 | signal dcc9 | snr 0000 | ber 001fffff | unc 00000000 | status 01 | signal e207 | snr 0000 | ber 001fffff | unc 00000000 | status 01 | signal db09 | snr 0000 | ber 001fffff | unc 00000000 |
