[linux-dvb] femon question

[Karsten Dello]

dear list,

may be this is a stupid question, but google couldn't help me :-)

i am running vdr on debian sarge,
my dvb-t-device is a terratec cinergy t2 usb box.

vdr and vdradmin work fairly well,
but i can't record all channels, probably due to insufficient signal 
quality.
i wanted to measure the signal quality using the femon command-line 
utility from dvb-apps 1.1.0.
but all i get is

using '/dev/dvb/adapter0/frontend0'
FE: TerraTec/qanu USB2.0 Highspeed DVB-T Receiver (TERRESTRIAL)
status 1f | signal 2337 | snr cbcb | ber 00000000 | unc 000000b1 | 
FE_HAS_LOCK
status 1f | signal 2337 | snr cbcb | ber 00000000 | unc 000000b1 | 
FE_HAS_LOCK
status 1f | signal 2337 | snr cbcb | ber 00000000 | unc 000000b1 | 
FE_HAS_LOCK
status 1f | signal 2337 | snr cbcb | ber 00000000 | unc 000000b1 | 
FE_HAS_LOCK

and so on.

any ideas?

help would be very much appreciated,

best regards
