ORCHID CITY SOFTWARE

The NRD525 Remote Control Application





       This application controls NRD525 communications receiver via your computer.
       Before the NRD525 will allow receiver computer control, the receiver must
       be upgraded with the CMH-532 Interface and have the correct RS-232c cable. 
       The application controls are wrapped around a comprehensive easy to use database.  
       The database is mainly for DXing and can sort by language, time, frequency,
       country, continent, and radio station.  So if you're just a shortwave
       content listener, you can easily find radio stations broadcasting 
       in almost any language.  As you scroll down the screen of the database file,
       you'll be able to send the frequency of each record to your receiver
       by clicking your mouse key or pressing a quick key on your key board.

       Besides the main DX Radio Database, the NRD525 Remote Control Application contains
       another database file that is especially unique to this program. It is a database        
       which allows one to search for transmitter sites and countries.  This database
       contains numerous records for transmitter sites around the world.  The sort routines 
       cover both country and cities. Each record contains the Country, City, Abreviations,
       Longitude and Latitudes of both your home base as well as the city where the
       transmitter is located.  With both positions filled in with the longitude and latitude,
       the program will calculate the beam from your site to the transmitter site.  

       Finally, the program contains a audio Spectrum Analyser that shows in graphic display,
       the signal you are listening.  This Spectrum Analyser is run through your computer's 
       sound card.  
     
      
       Take a look at the screen shots below.  The images are a little distorted due
       to poor copying.  


NRD525 SHOT

       This is a visual of the DX Radio Database screen.  Notice the two entry fields in               the top left corner with green background.  This is where you would enter the 
       time in UTC and the language that you want to view from the database.

       To the right top corner you will notice the Alternate Frequencies six fields.  These 
       fields display the Broadcast station's parallel frequencies for that scheduled 
       time.  For example, many times VOA broadcasts on a number of frequencies each hour.
       If this were true for the record you just pulled up, the alternate frequencies fields
       would should those frequecies.  Next to each frequecy is a button which you could
       press with your mouse and that would send the frequency to your reciever.  As you
       check each assigned alternate frequency, you could click on the VFO frequency to
       take you back.

NRD525 SHOT
       This visual shows the bottom of the DX Radio Database screen where are located a
       number of buttons that change the settings on the NRD525.  You can change the 
       Mode, the bandwidth, AGC etc.   

       Near the middle of the screen on the left is another entry field for sending a
       frequency to your receiver.  To send the frequency, type it in the required five(5)
       figure format i.e. 09445 or 15190 and press the F7 key or click on the button.  
       The frequency is setup on your receiver.

       Next to the Send data button is the "Send a Record" button.  Each time this button
       is pressed the highlighted record's frequency is sent to the receiver for setup.  The
       highlight bar automatically descends to the next record on the screen. 


       Echelon:  Notice below the Time and Language green fields, there's two Aqua'd
       background fields.  These fields are available to program you browse screen
       to highlight certain records as you browse the records up or down.  If you
       are curious to find all the stations that are from Peru and the language spoken is
       Spanish, you would type in Peru (capitalized) and the language Spanish (capitalized).
       Each time you bowsed a record with either of those or both, the screen fields would
       change colors to Aqua.  Nice.

       Sometimes a radio Station dominates a frequency.  If as the editor of your database, 
       you wanted to keep track of this, you would enter "Yes" in the record's field 
       that notates this.  Then when you are browsing the database and you come to a 
       record that dominates, the Radio Stations name field would appear with a 
       yellow back groud.   
       

      At the base of the browse window there is the "Time Line Bar" which represents the 
      Radio Stations schedule in a graphic bar image.  This bar corresponds to the actual 
      start and end time for the highlighted record.  If the schedule does not encompass the 
      current UTC, then the time bar appears as a GRAY color, but if the schedule
      encompasses the current UTC in your computer's record, the time line bar
      appears light blue or Aqua.  
     






The remote control application allows the user to program the browse screen. In this screen shot notice the fields in the browse that are highlighted. The user programmed the application to highlight all stations broadcasting in "Spanish" and from the Country of "Peru". This is the Echelon feature. There are so many radio station sometimes assigned to certain frequencies. With the Echelon feature, you can program the browse to highlight certain fields when a particular language or radio station gains focus in the database. It's like some one handing you a reference book full of radio stations schedules and all of the ones your are interested in are highlighted so you can thumb the entire book in a minute. In this screen shot notice the six extra fields located in the upper right hand corner of the screen. This area represents the Alternate Frequencies area. You have probably noticed in your listening to shortwave, that many of the larger radio stations broadcast on more than one frequency for a particular time. So, if you have kept your database current (it comes to you current), you can click on one or all of the alternate frequencies to see if one of them has better reception than the one your are listening to presently. Each click retunes your receiver to the alternate (one to six) frequency. After checking, you can click back to your VFO if you desire?

     This screen shot shows the HFCC database for B04 (Fall and Winter 2004/2005).  The
     browse functions and buttons are generally the same as the DX database with a
     few exceptions.  First there's not alternate frequencies listed.  Second, the
     browse screen does not indicate different characteristics by changing colors.  
     However, the HFCC database is very comprehensive.  It shows Radio Stations schedules,
     where they are beaming their transmissions, what days of the week they broadcast,
     how much power they are using, languages and other information.  

     The NRD525 is also controlable from this database.  The record's frequency can
     be sent to the receiver for setup which makes for easy searching for a good
     reception frequency.

The above screen shot shows the gray bar because the highlighted radio station's schedule did not encompass the current UTC time.

This screen shot shows the input form. With this form the user will input or change records in the database. As you may have noticed, the records can be edited and new records added. Usually, other database applications don't allow the user this privilege.


NRD525 SHOT The NRD525 Application has a spectrum type analyser included.
      This program is user friendly.  A HELP file and Transmitter Site database are
      included with this application.  Although the NRD525 has been around for a
      number of years, it is still one of better receivers around.  Controlling the 
      receiver remotely makes it more interesting to use.  Click on the buy button
      below for details.

      The above screen is the for setting up the computer and receiver.  Since the program
      was tested here using an NRD525, the settings should be ready for you to start.
      Once you have the settings correct, just click on "Connect".

      In the screen shot above, you probably noticed that there's an option of selecting
      one of eight(8) comm ports.  Some other programs don't even give more than one
      comm port option.  This program allows you to streamline your computer and receiver.
