Expedio Digital Electronic News Gathering Radio 

The Expedio may be used as a standalone simplex radio with a internal in the MPEG2 Encoder / 
Decoder system or utilize external MPEG2 units and feed DVB-ASI with 188byte format on the 
Input and have DVB-ASI out coming out on the Receiver.    

This equipment has been tested and found to comply with the limits for a Class A digital device, 
pursuant to part 15 of the FCC Rules.  These limits are designed to provide reasonable protection 
against harmful interference when the equipment is operated in a commercial environment.  This 
equipment generates, uses, and can radiate radio frequency energy and, if not installed and used 
in accordance with the instruction manual, may cause harmful interference to radio 
communications.  Operation of this equipment in a residential area is likely to cause harmful 
interference, in which case the user will be required to correct the interference at his expense.  
Any external data or audio connection to this equipment must use shielded cables.

 

The product is a simplex digital radio.  The following sections describe the TX system, RX 
system, followed by sub-system components.  Please reference the accompanying block 
diagrams for clarification.

 

We will follow the typical end-to-end progression of a radio system starting with the TX baseband 
inputs, to the COFDM modulator, followed by the upconversion process and the power amplifier.  
We then proceed to the RX preamplifier input, the down conversion process, followed by the 
COFDM demodulator and baseband outputs.
