[mythtv-users] SNR reported by kernel dvb for HD-5500 card

[Tom Dexter]

I'm using HD-5500 cards for OTA DTV.

Does anyone know if the signal to noise reported by the HD-5500 card
is out of whack?  I think it almost has to be.

If I monitor it with femon from the media-tv/linuxtv-dvb-apps package
I get what appears to be a correct signal strength (it usually jives
with my Samsung HD receiver).  The snr however is never beyond the 8%
to 13% range.  I can't believe it would even get a lock if that were
correct:

femon -a 0 -h
FE: LG Electronics LGDT3303 VSB/QAM Frontend (ATSC)
status SCVYL | signal  94% | snr  12% | ber 00000000 | unc 00000000 |
FE_HAS_LOCK
status SCVYL | signal  96% | snr  13% | ber 00000000 | unc 00000000 |
FE_HAS_LOCK
status SCVYL | signal  93% | snr  12% | ber 00000000 | unc 00000000 |
FE_HAS_LOCK
status SCVYL | signal  98% | snr  13% | ber 00000000 | unc 00000000 |
FE_HAS_LOCK
status SCVYL | signal  93% | snr  12% | ber 00000000 | unc 00000000 |
FE_HAS_LOCK
status SCVYL | signal  96% | snr  13% | ber 00000000 | unc 00000000 |
FE_HAS_LOCK

It'll appear like that when I'm getting flawless reception.

If I use the F7 key to bring up the signal monitor in my mythfrontend
it'll show around 3.9dB.

My Samsung receiver only shows strength, not quality...and as I said,
it jives with the above signal strength.  When I had my Sony
DHG-HDD500 HD DVR I believe the quality usually showed 'good' or
better.

There's no way that's even close is it?
