NRD545 Remote Control Application


     The Japan Radio Corporations newest Communications Receiver is the
     Digital NRD545.  It has a comprehensive CPU that allows the 
     receiver to be controlled in a number of new and unique ways.  JRC
     had a computer program written for the receiver and although it looked
     good, it can only be assigned to commport 2 of your computer.
     Enough Said.

     The NRD545 Remote Control Application from Orchid City
     Software, was written focusing on the Shortwave/DXer as the primary 
     user although the Shortwave Listener will find the program an excellent
     source of Radio Station Schedules.  The application is a remote
     control program with a set(6) of comprehensive database files.  These
     database files are explained in detail below. The application is a   
     serious software tool which will enhance your dxing efforts. 

     Take a look at the screen shots below:

     The first shot is one of the numerous browse Screens.  It is 
     the database of DX enities.  Each record/line shows the Frequency, Station
     Name, Start/End Schedule, Language, whether it dominates the frequency, 
     City/Site, Country, Continent, Date Entered, Bandwidth Code, Mode Code,
     AGC Code, PBS Setting, BWC Setting, and Notch Setting Positive/Negative.
     That's a lot of information as it sets up the receiver as you select
     each record.  However, many of the input fields can be ignored if the user wishes. 

     The browse screen is loaded with functions.  Each button, activated with the
     mouse, sends a command to the receiver.  It's very easy to select different
     functions or modes using the remote application.  

     Here's a scenario.  Has this ever happened?  You're at your desk with your 
     NRD545 beaming.  Finally you're able to hear a station you'd been waiting 
     to hear for a long time.  It just needs a slight tuning and maybe a little
     bit of Pass Band Shift?  You reach over to the receiver to change the frequency.
     The control panel is dark and you touch the wrong control.  Gone!  That will
     not happen with the NRD545 Remote Control Application.  After all you are
     selecting functions that are shown on your computer screen.

     Have you ever wanted to scan a band of frequencies? 

     Let's think about a database for a moment.  The NRD545 Remote Application has a 
     comprehensive database of Radio Stations records.  Each record contains the
     following: 1. Radio Station Name
                2. Frequency
                3. Schedule Time for that frequency
                4. Language that the station is broadcasting for that Scheduled Time
                5. City where the radio station transmitts
                6. Country
                7. Continent 

     Additionaly, the database lists any alternate frequencies for that period, Power
     and much more.

     As an example: When band scanning and a faint carrier is heard on a frequency.
     Wanting know who is on that frequency, it is just a simple matter to type in the frequency
     and the database skips to the record on that frequency.  One can also search by
     Radio Station name, Country, Language, Schedule, Continent, as well as the frequency.
     The database is very powerful.

     Have you ever wanted to plug into the parallel frequency?  As mentioned above,
     some records have alternate frequencies included where you can click a button
     and your receiver will immediately tune to that alternate frequency.  If 
     the alternate frequency isn't better than the original frequency, you can
     click another button to return to the basic frequency.  

     On the shortwave broadcast bands, frequency allocations are set at every
     5 KHz apart.  You can't tune at 5 kHz chunks with the NRD545.  However, the
     NRD545 remote tunes up or down at 1 kHz, 5 kHz, or 10 kHz chunks just by 
     clicking a button.

     This is a view of the database for DXing.  If you compare it with the graphic 
     below, you'll see a few differences.  The screen below is the latest upgrade.


     This is another view of the same database for DXing.  Note the subtle changes of 
     some of the fields on each screen shot.  Notice the Time Line Bar beneath
     the browse screen.  This is a unique display that gives the user a quick 
     graphic reference of the Radio Stations Schedule for that frequency.  

     The bar's color changes as the records are accessed depending on whether or 
     not the current time falls within the Radio Station's schedule.  If the current
     time does correspond to the schedule, the bar displays in Aqua.  If the 
     current time does not correspond to the station's schedule, then the bar is
     displayed in gray. 




     The immediate above image is the "RTTY" screen.  Yes the NRD545 is able to copy
     RTTY signals.  The baud rates available are 37 to 75 baud.  This screen is the 
     basic RTTY screen.  The slider bar allows the operator to select the baud rate 
     easily.  The RTTY function has a small database of utility stations which 
     includes a few RTTY stations.  This database as well as all of the database files
     in this application can be Updated or Changed by the user.


     This is an image of the Site Database.  This database is very unique.  Besides 
     containing information on various Shortwave Broadcasters' Transmitter sites, i.e.
     Country, City, it also contains the coordinates of the sites already entered.  
     As the operator enters new site records, he includes his own QTH coordinates and 
     the relative beam heading of the distant transmitter site is calculated.  I use
     it to decide which of my antennas receives different signals from different headings.

     The NRD545 Remote Control Application is offered with Four database files: 

     1. DX International & National Broadcast - This is the main database file.
     2. Transmitter Sites - This database contains records for transmitter sites.
     3. Utility Radio Station -  This database contains records of utility stations
                                 such as Fix Shore Stations, RTTY stations etc.
     4. Broadcast Schedules  - This database allows the user to save raw broadcast 
                               schedules to be copied later.  For example, many broad
                               casters issue a new schedule during the year.  This 
                               information can be copied and pasted into this database.
