HERE ARE FREQUENTLY ASKED QUESTIONS
A self-test simply involves checking your receiver to confirm that you are receiving a usable signal off of the satellite (Galaxy 17).
The process is straightforward: You simply go to one of the previously defined channels on Galaxy 17 (ABC NEWS Channels) and then note your signal strength and quality to confirm that you are a) looking at the correct satellite and b) receiving a good quality signal.
When I do a self-test, what channels should I expect to find?
You should expect to find at least two full time video channels when searching Galaxy 17: ABC NEWSONE LIVE channels There are a number of occasional use channels that news organizations use for location feeds, and other special events which may show up in your channel list if you do a scan.
ABC News is located at Transponder Frequency 12010, Polarity Vertical (V), Symbol Rate 11574. If you scan on this transponder frequency, you should find two ABC News feeds – ABC NewsOne Live and ABC NAC 2. If they are not transmitting live news reports, they have a graphic on the screen with the ABC logo, transmission information, and sometimes test tone for audio. If you participated in prior events, you should see a WILLOW LIVE and/or WILLOW WEST channel on your system, but most likely both will be dark (no signal) until our Full Path tests. If you have any question about whether you are on the correct satellite or seeing what you should, please call Fresh Air Media at 530 888-7676.
3. How do I determine the signal quality on my receiver?
On the GeoSatPro HDVR 1200 you should press the "i" info button on the remote control. It will display a banner on the bottom of the screen that includes S and Q numbers. The S is for Signal Strength and the Q is for Signal Quality.
4. What is the difference between signal level and signal quality?
In very general terms, "signal level" represents the strength of the connection between the receiver and the LNB and satellite antenna (and thus the satellite signal itself). A very low or non-existent signal level indicates that there is something wrong with the basic connection to the satellite -- perhaps the cable has been severed or the LNB has failed, for example.
Signal quality, on the other hand, represents the strength and robustness of the actual satellite signal you are viewing. Therefore, the signal quality value can change when you switch to another channel (whereas the signal level remains relatively constant as long as you are connected properly to the satellite dish / LNB).
The signal quality value is basically the manufacturer's algorithm to calculate how much error correction is necessary to display a usable signal. This algorithm is software-based and can change from manufacturer to manufacturer and from one firmware version to another. Therefore, even the same exact signal can read differently from one receiver to the next.
5. What is the channel number for FRESHAIR14, FRESHAIR15 or the WILLOW LIVE or WILLOW WEST Channels on my receiver?
The channel number for the event channels are variable and depend on when the channel was captured and how it was named when it was first captured (or renamed after it was captured).
The current channel NAMES are either FRESHAIR14, FRESHAIR15, WILLOW LIVE and WILLOW WEST.
6. What is horizontal and vertical polarity and why does this matter?
Horizontal and vertical polarity are terms used to describe the orientation of the signal being transmitted by the satellite. The signal can be transmitted in a horizontal or a vertical polarity on the same frequency, thereby doubling the effective number of transmissions available on the satellite at the given frequency.
Some LNBs are designed to only receive at a single polarity; others can receive at both vertical and horizontal polarity but need to be told which polarity to align themselves too. The LNBs installed on almost all Willow Creek satellite dishes fall into this latter category.
The way the receiver tells the LNB which polarity to align itself to is by sending a DC voltage of either 13 volts (V) or 18 volts (H) via the coax cable that connects the receiver to the LNB.
7. What are the NEXUS transmission parameters?
To confirm the transmission parameters, please send an email to
requesting them. We will send back an email with the transmission
Is the GLS event audio feed Mono or Stereo?
The audio portion of the GLS satellite and streaming signal is a full stereo audio (Left / Right) program.
9. What if I can see video on the GLS feed but can’t hear the audio?
There are at least a couple of potential causes for this. Use the
following procedure to troubleshoot:
- First, make sure that the lack of audio isn’t a result of your
sound system configuration. Check the signal path of your audio system.
- If everything checks out OK, try bypassing your sound system and feeding the receiver’s Audio Out (RCA Connector on the back) signal directly into an amplifier or some other device where you can monitor the signal directly.
- If you have audio directly off the receiver, go back and check
your sound system signal path.
- If you don’t have an audio signal off of the RCA Audio Out connectors, try deleting the existing Willow Channel then do a transponder scan. This will recapture the embedded PID information for the signal.
- If this is not successful, call Fresh Air Media at
530-888-7676 for further assistance.
10. What can I do if my audio is out of sync with the video signal?
If the sync issue is one which has *always* been present in your system and which stays at a consistent value, you may want to review your signal path and determine if there is a system-induced sync issue in your setup.
However, if this symptom is something which “came on all of a sudden without warning”, there are factors that can create this situation in a receiver and which are generally outside of your control. In this case, you can momentarily switch off the current receiver channel to another channel and then quickly return. This typically re-synchronizes the signal and fixes the problem.
Having said that, this is not an easy choice if the program content is in the middle of a session and you have 500+ people who will view the switch back and forth. Use your judgment as to whether the channel switch is worth it or not. If the sync issue is not too severe, it may not be worth the interruption. Also, if you are close to the end of a session, you may be able refrain from doing the switch until during the break.
Another option is to switch to the streaming video feed. Again, use your
best judgment here.
Whatever the choice, make sure that you consult
with your Producer before doing anything! Any action should only be
initiated with their full approval.
11. Why can't I see anything on the event channel when doing my self-test or
when viewing the channel on my receiver in between satellite tests?
The GLS signal is only available during schedule transmission times. Therefore, if you select the event channel during a time when there is no transmission, most likely you will not see anything.
However, if you select the WILLOW LIVE or WILLOW WEST channel during a time when there *is* a transmission (like during a satellite test or the event itself) and you cannot see a signal, call Fresh Air Media for assistance (530) 888-7676.
12. I can't see a picture and I'm not sure I've got the cable from the satellite dish
plugged into the right input on the receiver. Which input should the cable
be plugged in to?
The correct input from the satellite dish to the receiver it is the “LNB IN” input.
