I'm getting a 75 signal strength (normal for us is 80 to 88) and we seem to be 
receiving ok.

Hello everyone,

My 3.7 meter dish is struggling some to pick up the NOAAPort signal
today. I use a Novra S75+ (latest firmware patch), a NORSAT 3120 LNB, and 
using the Novramon software from Jose Nieves, I see this after running it 
for about an hour:

       Frequency: 1193.500000
      SymbolRate: 6.349000
        LNBFault: ok
      SignalLock: on
        DataLock: on
SignalStrength%: 77
            VBER: 0.00e+00
          Errors: 1621
       ErrorRate: 0
DemodulatorGain: 78
   NoiseEstimate: 11
    DataSyncLoss: 0
     ClockOffset: 33
  FrequencyError: -1

It's never a good thing when the Demod gain is higher than the signal 
strength. I like to see a ClockOffset of 30 or less for excellent 
reception. Wondering if it was my system, I logged into the College of 
DuPage's NOAAport receiver. They also use the same LNB and S75+ wih the 
latest firmware, but they have a 3.0 meter dish.

  Frequency              1193.500000
  Symbol Rate            6.349000
  VBER                   1.6539e-02
  Viterbi Rate           7
  LNB Power              ON
  Polarization           1
  Band                   0
  Long Line              1
  Hi Voltage Mode        1
  Signal Strength        75
  DemodGain              59
  C/N                    100.000000
  Signal Lock            on
  Data Lock              on
  Uncorrectables         127
  Noise Estimate         13
  Clock Offset           98
  Frequency Error        0
  ADC Midpoint Crossing  22
  ADC Clipping Count     255
  Digital Gain           0
  Clamping Count         16

With this latest firmware update of the S75+, the largest error rate you 
can have is indeed 1.6539e-02. And, doing an "ldmadmin watch", not 
surprisingly, yields ZERO products from them.

So, anyone know what's going on? As they say, "it isn't us"....
