Hello. I have got CR+CL+KUHV LNB on the DVB-S dish looking to the Yamal 201 at 90*, and there are 3 different cables go down to my server from that dish (one cable to one lnb type). When i am trying to scan channels from "4084 R 2500" it does not scan, but it scans perfectly from "4042 R 8681". And when i am szapping to some channel from 4084 it is scanning fine too at the same time (but polarization is dumped wrong for some reason which i can not understand)! Szap shows very good parameters of signal (too good to be true i think:): sat 0, frequency = 4084 MHz V, symbolrate 2500000, vpid = 0x0000, apid = 0x1001 using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0' status 03 | signal 97.79% | snr 43.95% | ber 00000000 | unc 00000000 | status 03 | signal 100.00% | snr 58.75% | ber 00000000 | unc 00000000 | status 1f | signal 100.00% | snr 70.75% | ber 00000113 | unc 00000000 | FE_HAS_LOCK status 1f | signal 100.00% | snr 71.66% | ber 00000000 | unc 00000000 | FE_HAS_LOCK status 1f | signal 100.00% | snr 72.57% | ber 00000000 | unc 00000000 | FE_HAS_LOCK status 1f | signal 100.00% | snr 72.45% | ber 00000000 | unc 00000000 | FE_HAS_LOCK status 1f | signal 100.00% | snr 71.90% | ber 00000000 | unc 00000000 | FE_HAS_LOCK Here is output from scan when i am trying to scan to previously tuned frontend: using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0' 0x0000 0x0015: pmt_pid 0x0be4 NetService -- SILVER (running) 0x0000 0x0016: pmt_pid 0x0be7 NetService -- Record-2 (running) 0x0000 0x0019: pmt_pid 0x0bfa NetService -- Business FM (running) 0x0000 0x001a: pmt_pid 0x0bfc NetService -- 107-8 (running) 0x0000 0x001b: pmt_pid 0x0bfe NetService -- Pomestnoe (running) 0x0000 0x001c: pmt_pid 0x0c00 NetService -- Resurs-2 (running) 0x0000 0x001d: pmt_pid 0x0c02 NetService -- DOPO*HOE (running) 0x0000 0x001e: pmt_pid 0x0c04 NetService -- Energia (running) 0x0000 0x0020: pmt_pid 0x0c08 NetService -- Avtoradio (running) 0x0000 0x0023: pmt_pid 0x0c1a NetService -- Shanson (running) 0x0000 0x0024: pmt_pid 0x0be2 NetService -- Radio Alla (running) 0x0000 0x0025: pmt_pid 0x0be5 NetService -- Mayak (running) 0x0000 0x0027: pmt_pid 0x0be3 NetService -- Radio Record (running) 0x0000 0x002a: pmt_pid 0x0be6 NetService -- FINAM FM (running) 0x0000 0x0039: pmt_pid 0x0be0 NetService -- Humor FM (running) 0x0000 0x003a: pmt_pid 0x0be1 NetService -- G.2 (running) Network Name 'NetworkService' dumping lists (16 services) SILVER:4084:h:S90.0E:22500:0:4097:0:0:21:0:0:0 Record-2:4084:h:S90.0E:22500:0:4099:0:0:22:0:0:0 Business FM:4084:h:S90.0E:22500:0:4130:0:0:25:0:0:0 107-8:4084:h:S90.0E:22500:0:4136:0:0:26:0:0:0 DOPO*HOE:4084:h:S90.0E:22500:0:4168:0:0:29:0:0:0 Energia:4084:h:S90.0E:22500:0:4122:0:0:30:0:0:0 Avtoradio:4084:h:S90.0E:22500:0:4200:0:0:32:0:0:0 Shanson:4084:h:S90.0E:22500:0:4108:0:0:35:0:0:0 Radio Alla:4084:h:S90.0E:22500:0:4106:0:0:36:0:0:0 Mayak:4084:h:S90.0E:22500:0:4212:0:0:37:0:0:0 FINAM FM:4084:h:S90.0E:22500:0:4104:0:0:42:0:0:0 G.2:4084:h:S90.0E:22500:0:4102:0:0:58:0:0:0 Radio Record:4084:h:S90.0E:22500:0:4154:0:0:39:0:0:0 Humor FM:4084:h:S90.0E:22500:0:4151:0:0:57:0:0:0 Pomestnoe:4084:h:S90.0E:22500:0:4150:0:0:27:0:0:0 Resurs-2:4084:h:S90.0E:22500:0:4160:0:0:28:0:0:0 Done.
