{Single, Dual, Quad} Sundtek SkyTV Ultimate / Re:Tuning issues with certain frequencies

« am: April 15, 2013, 10:37:40 Nachmittag »

I live in a flat and its a communal dish with distribution boxes, I have had the connection examined by an engineer and it was fine. I would think the LNB is always on so I ruled out drift from heat.

I have a friend with the same device, should I try that one? If it was a faulty device would it not cause a problem on other frequencies?

When trying to tune to the frequency now

SIGNAL: [............................ ] ( 85%) BER: 0 FREQ: 12343500 Hz LOCKED: YES SYS: DVB-S2 SYM: 29500000 FEC: FEC_3_4 MOD: QPSK VOLTAGE: H(18V) TONE: ON

But after a while it goes back to no signal

I get the same result when trying to tune, I tried 1000 hz intervals between what the auto detect muxes suggests, but still no luck.

Sometimes it works for a while then starts throwing errors

{Single, Dual, Quad} Sundtek SkyTV Ultimate / Tuning issues with certain frequencies

« am: April 15, 2013, 08:20:43 Nachmittag »

I keep getting continuity errors with certain frequencies but not with others, I can't find any pattern for this.

e.g

/opt/bin/mediaclient -m DVBS2 -f 12343500 -M QPSK -S 29500000 -V H -E 3/4
Using device: /dev/dvb/adapter0/frontend0
Setting DVB-S/S2 tune Parameters
using HI/LO Band frequency: 12343500
Modulation: QPSK (DVB-S)
Symbolrate: 29500000
Voltage: 18 Volt (Horizontal)
FEC: 3/4
Tone ON
Frequency: 1743500
Syntax OK
Checking for lock:
..........

gives an readout of this

== reading digital TV signal ==
SIGNAL: [ ] ( 0%) BER: 0 FREQ: 12343500 Hz LOCKED: NO SYS: DVB-S2 SYM: 29500000 FEC: FEC_3_4 MOD: QPSK VOLTAGE: H(18V) TONE: ON
SIGNAL: [ ] ( 0%) BER: 0 FREQ: 12343500 Hz LOCKED: NO SYS: DVB-S2 SYM: 29500000 FEC: FEC_3_4 MOD: QPSK VOLTAGE: H(18V) TONE: ON

But sometimes this works fine. I don't believe it is a cable / LNB issue since I can tune into other frequencies fine and it is a communal dish.

I tried tweaking the frequency slightly but this did not help.

When I tune to other frequencies it works fine and is stable.

e.g
/opt/bin/mediaclient -m DVBS2 -f 10847000 -M QPSK -S 23000000 -V V -E 2/3
Using device: /dev/dvb/adapter0/frontend0

using HI/LO Band frequency: 10847000

Voltage: 13 Volt (Vertical)
FEC: 2/3
Tone OFF
Frequency: 1097000
Syntax OK

. [LOCKED]

Have you got any suggestions I can try to resolve this?

Thanks
