Re: dm1105 scan but won't tune? [RESOLVED]

OK, progress (idiot error?)

My problem was OptusB1 requires a 45 degree skew on the LNB on the dish itself.

So now I can do an szap as follows:
TV3:12456:h:0:22500:512:650:1920

./szap -l 11300 -c channels-conf/dvb-s/OptusD1E160 TV3
reading channels from file 'channels-conf/dvb-s/OptusD1E160'
zapping to 1 'TV3':
sat 0, frequency = 12456 MHz H, symbolrate 22500000, vpid = 0x0200, apid = 0x028a sid = 0x0780
using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'
status 1f | signal cd82 | snr be5c | ber 0000ff00 | unc fffffffe | FE_HAS_LOCK status 1f | signal cd07 | snr be9e | ber 00000000 | unc fffffffe | FE_HAS_LOCK status 1f | signal cd07 | snr be4a | ber 00000000 | unc fffffffe | FE_HAS_LOCK


New problem though - I can now no longer scan with the LNB skewed!!

S 12456000 H 22500000 AUTO

./scan dvb-s/OptusB1-NZ -l 11300

Any ideas?

Things to note when you install your own satellite dish and card:
1) Make sure you understand the LNB requirements for your satellite. I needed to skew mine on the dish by 45 degrees - wasted a lot of time getting odd results from a vertically mounted LNB 2) Understand your LNB specs. Mine had a 11300Mhz LSOF, which needed allowance for when szapping, scanning and in VDR

My system:
Fedora 13 on a dual core intel platform.
combination of DVB-C (TT-1501 and TT-2300), PVR-500 and DVB-S (dm1105 based and TT-1401) cards
Used on New Zealand cable TV, Freeview TV and Sky TV

my most recent fixes:
Use the '-r' switch in szap, to set the front end up for TS recording.
Use the '-l 11300' in szap to configure for the LNB
Use diseqc.conf file and "setup>LNB>DiSeqc ON" in VDR to set the LNB settings
