Technical Bulletin
Date: March 21, 2016
Subject: DISH Network Satellites Upgraded to 8PSK Modulation
Products Affected
TracVision® L3, S3, R1DX, R4, R5, R4SL, R5SL, and R6DX
Problem Description
DISH Network® has converted their satellite transmission signals from QPSK modulation to a more efficient
8PSK format. This newer format improves the customer experience by providing more high-definition
programming and additional content. The new format is not compatible with many older DISH Network
receivers, and impacts the ability of some older KVH antenna systems to identify and track DISH Network
satellites.
IMPORTANT! KVH’s latest generation of TracVision products (RV1 and A9) are fully compatible with
8PSK format. The instructions for updating the RV1 and A9 satellite library are provided at the end
of this bulletin.
Problem Solution
The products affected will only be able to track DISH Network’s 119°W satellite. Verify that the following
tracking parameters are configured in the system.
Parameter Satellite 119°W
Polarization LHCP RHCP
Frequency 12530 MHz 12632 MHz
Symbol Rate 20000 20000
FEC Code 6/7 6/7
Network ID 0x0003 0x0003
Decoding Type DSS DSS
Update the tracking parameters as described on the next page.

Updating the Satellite Library in an RV1 and A9 System
Service providers occasionally change the tracking parameters of their satellites, necessitating an update to
the data in the TracVision satellite library. You can update the system’s satellite library to the latest version at
any time by downloading the file from KVH’s Update server and uploading it to the TV-Hub. When you update
the library, the new version simply overwrites the previously installed version.
IMPORTANT! With the exception of user-defined satellites, updating the satellite library overwrites
any changes you have made to the satellite’s tracking parameters. All parameters for preset
satellites revert to their factory default settings.
Use one of the following methods to update the satellite library:
Using an Onboard Network with Internet Access
1. Connect your computer to the same network as the TV-Hub.
2. At the Updates page of the web interface, select the satellite library. Then select Download Update.
This will download the latest version of the library file onto your computer.
3. Select Install Update. Then navigate to and select the library file (it has a .xml extension) saved on
your computer. It will only take a few seconds for the update to complete.
Using a SmartPhone or Tablet
If you have an Apple® iOS or Google™ Android™ smartphone or tablet, and your device has an Internet
connection, you can use the TracVision TV/RV App to download the latest library file and upload it to the
system. You can download the App for free from the Apple iTunes® App Store™ or Google Play Store.
Using a Computer with Internet Access
If your computer has an Internet connection, you can use that connection to download the library file. Follow
these steps:
1. Download the latest version of the library file onto your
computer from the KVH website (go to www.kvh.com/
Support/Product-Support-Library/Software-Updates).
2. Once you have downloaded the file onto your computer, use
the same computer to access the TV-Hub’s web interface.
3. At the Updates page of the web interface, select the satellite
library then select Install Update. Navigate to and select the
library file (it has a .xml extension) saved on your computer.
It will only take a few seconds for the update to complete.
