PCTV 461e not feeding LNB #3731
Comments
not an openelec problem. and btw did you really post a dmesg from non-working fedora box here ?? |
I neither works on OpenELEC or Fedora. All I could get out of OpenELEC was a log of these: The logs on Fedora seemed more informative, perhaps because I could corelate it with scandvb. |
Fixes a8293 failure to raise LNB voltage in PCTV 461e DVB-S2 Stick affecting multiple users over several years as found here: http://www.linuxquestions.org/questions/linux-hardware-18/pctv-dvb-s2-stick-461e-not-feeding-lnb-4175529374/ https://www.linuxtv.org/wiki/index.php/Pinnacle_PCTV_DVB-S2_Stick_(461e) OpenELEC/OpenELEC.tv#3731 Caused by vIN undervoltage lockout (status register bit 7) when raising LNB to 18V. Addressed by using the higher-precision voltages available on the a8293 to gradually increase (slew) the voltage when voltage increases are requested. Adds volt_slew_nanos_per_mv to a8293_platform_data struct for specifying slew rate. If value is <1 or non-sane (>1600), the original no-slew version for a8293_set_voltage is used.

I bought a PCTV DVB-S2 Stick (461e) because it was on the supported list on linuxtv.org ( http://www.linuxtv.org/wiki/index.ph...2_Stick_(461e) )
However when I inserted it into my mediaserver with kaffeine it did not find any channels. I neither had any luck installing a OpenELEC system. Only once it looked like it got some signal.
Trying to attach a satellite finder indicated that no power was put on the cable for the LNB. Trying to insert the stick into a Windows 8 machine and installing the PCTV software, proved that the stick indeed did feed the LNB with power.
Next I tried to insert the stick to my laptop, with the satellite finder too. When running scandvb the sattelite finder went active for a few seconds, and the got silent. Rerunning scandvb gave no response. But removing the stick and reinserting it would repeat this when running scandvb.
This leaves me to suspect that the stick is reset during the scan.
My logs from the Fedora system can be seen here:

Anyone have some good ideas
