BPS PLP Issue (3.0)?

Post by Trip »

Nick,

I'm having a minor issue with a local 3.0 signal. I have two signals near me running 3.0 with an extremely robust BPS PLP (PLP16) and they behave very differently.

16: sfi=0 mod=qpsk cod=2/15 layer=core ti=cti lls=0 lock=1
-> Required SNR: AWGN -6.23 to -5.55 dB, Rayleigh -5.72 to -5.06 dB
-> PLP Bitrate: 0.033 Mbps

WHUT, I can lock all three PLPs without issue, and I get some BPS packets out of it.

WBFF, by contrast, if I try to lock all three PLPs, the tuner flips out as if it's swapping rapidly between the two, and this continues until I change the channel.

As an alternative, I tried to lock just PLP16, which takes 5 seconds to lock and then dies after 10 seconds with an empty file resulting. WHUT behaves the same way (though it took like 6 or 7 seconds to lock before dying at 10 seconds), so this specific issue is probably the low data rate rather than whatever's wrong with WBFF.

Any ideas?
