Husker Sports Network

Digital Satellite System


Beginning June 11, 2017 Husker Sports Network programming on the DCR-974 Digiceiver is delivered via the SES-11 satellite, located at 105 degrees West Longitude.  This is the same satellite as the major national radio networks, therefore you will not need a separate satellite antenna (dish) for the Husker Sports Network DCR-974 receiver. The most recent changes were on August 18, 2019 when our satellite channel/frequency was changed as we prepare to accomodate 5G wireless communications needs.

 

Since you will be connecting the Husker Sports Network DCR-974 to an existing dish, the receiver LNB power is turned off.  This is the normal mode, as one of your existing satellite receivers will already be providing LNB power.

 

Basic connections for the DCR-974 are as follows

  1. Connect a coax cable from the receiver rear panel coax F connector to an open port on your existing SES-11 satellite dish splitter.  If you do not have any open ports, you will need to obtain a larger or additional splitter.
  2. Connect audio to the proper audio connectors on the Husker Sports Network DCR-974.  Channel B will be used as the primary NET-1 Husker Sports Network channel (please note, this is channel B and not channel A).  Channel D is used as our NET-2 secondary programming channel, and Channel C is used as our NET-3 tertiary programming channel.   Channel A is reserved for future use.  The Husker Sports Network channels are mono, but feed to both the LEFT and RIGHT outputs - therefore you should install the receiver with stereo wiring to station equipment for future stereo network programming.  Audio connector pinouts are below.
  3. Connect AC power to the DCR-974.  Make sure the receiver is plugged into adequate surge protection.  The value of the receivers is about $5,500.00.

 

 

Contact Closures

The Husker Sports Network DCR-974 uses digital contact closures instead of subaudible tones.  Eight contact closures are available, four for our NET-1 programming and four for our NET-2 programming.  Access is via the ICP Remote Switch Closure Module (part # 100368).  Install the module into the connector labeled REMOTE CLOSURE PORT 1 on the back paned of the DCR-974.  You cannot connect contact closures directly to the DCR-974, they must be via the Remote Switch Closure Module! 

 

An excellent source of a breakout board for the contact closure module is Winford Electronics.  We suggest ordering a DB-37 male to female cable in addition to the breakout board, so the board does not break the satellite receiver connectors.  Total cost for both the breakout board and extension cable is less than $50.  We use these at our uplink.

 

The following contact closures are used (no contact closures are available for programming on our NET-3 channel)

There are several front panel lights on the DCR-974

POWER: Indicates AC power has been applied to the receiver.

LNB: If this light is off, conditions are normal.  If the light is on, it can indicate a LNB problem.

FAULT: Indicates some type of fault/error with the receiver.  Power down the unit for 30 seconds then turn it back on and see if the fault alarm clears (it will illuminate for the first few seconds when the receiver reboots, this is normal).

DEMOD: If on steady, the receiver is locked onto Husker Sports Network digital audio.  If flashing, indicates a marginal satellite signal.  If off, you will not have any audio.

CXR ID: Husker Sports Network transmits a unique digital carrier identification signal.  When this indicator is lit, the receiver is positively locked on to the Husker Sports Network digital system (and not another satellite signal).

DN LOAD: If flashing, new software has been downloaded to your receiver.  If steady, you may have a software error and should reboot the receiver.

LOCAL: Blinks when in local control mode.  You must be in local control mode to be able to change receiver settings.

 

Rear Panel Indicators

PORT1: not used

PORT2: not used

Ethernet RX: future use when receiver connects to your computer LAN

TX: future use when receiver connects to your computer LAN

DRIVE: blinks when the internal hard drive is being accesses

LED1 & LED2: blinks when playing internal audio

 

Signal Strength

The front panel display will show a bar graph and numeric readout of signal strength.  To bring up the signal strength display

1. Press the right arrow CURSOR button until you see DEMOD, then press ENTER.

2. Press the PAGE UP button until you see SIGNAL STRENGTH.

 

A signal strength of 10.0 or above is acceptable, although your receiver will work with lower settings. 

 

You may also check signal quality by displaying the receiver SYMBOL ERROR RATE.  While viewing the signal strength, press the PAGE DOWN button once.  The receiver should now display Symbol Error Rate.  A good dish alignment and system will display a SYMBOL ERROR RATE of 0.0

 

Husker Sports Network DCR-974 Receiver Settings

The following settings were pre-programmed into your receiver before it was shipped, and should never need field adjustment.  In case your station would suffer a major satellite failure, please prepare contracts.  Do not change these settings unless you are under the supervision of Husker Sports Network technical support staff.
