Start the "TTI Transmitter Programming" software byclicking it's icon located on the Windows Desktop.4.) You must know the number of the Serial (Com) Port youhave attached the transmitter to. The software comes ready towork with Com 1. If you are using Com 2, 3, or 4, you mustperform the following: a.) Select "File" - "Properties" from the HyperTeminal Taskc.) Select "RUN" from the Start Menud.) Type "a:\setup" in the white bare.) Select "OK"f.) Follow the on screen instructions.g.) Remove disk when finished.JOEY'S VHF VOICE TRANSMITTER
Bar. b.) From the "Phone Number" tab, select your Com Port in the"Connect Using" pull down menu. Select the "Direct to Com___" line that correlates to your Com Port. c.) Select "OK" from the bottom of the window d.) Your Com Port selection is automatically saved.5.) Connect a 9 VDC battery to the battery terminal leads foundon the programming cable, and turn ON your Transmitter.At this time, your computer screen should look similar to thefollowing screen shot:Here are some commands to become familiar with:f..........Begins the New Frequency programmingsequence.v..........Verifies the frequency that is currentlyprogrammed in the transmitter.c.........Selects CLEAR transmission mode (forunits equipped with scrambling).s..........Selects SCRAMBLE transmission mode (forunits equipped with scrambling).Remember: All commands are lower case letters.6.) Begin by VERIFYing the information about your transmitter.Type a v.Immediately upon your entering a "v", the program will report the unit'sID (CTR-751/V) , and the frequency that is programmed into the currentchannel. If your transmitter is equipped with scrambling capabilities, thiswill be noted with an "S" after the model number (CTR-751/VS), andwhether the unit is in scrambled mode or clear mode (noted with a "c"or an "s" before the frequency notation). The screen will look somethinglike this:7.) Program your frequencyType an f.
The computer will respond with "=1", as follows:8.) The "1" is the 'hundreds" digit in your frequency (ie: 1xx.xxxxMhz). Now type the next 5 digits of your frequency.Here is some information on VALID frequencies:Your available frequencies are spaced in 12.5 kHz steps, beginningwith 150.0000 Mhz and ending with 174.0000 Mhz.Simply put, "12.5 kHz steps" means that your frequency must end inany of the following configurations:xxx.x000xxx.x125xxx.x250xxx.x375xxx.x500xxx.x625xxx.x750xxx.x875xxx.x000The first available frequency to you is 150.0000 Mhz. Thesecond is 150.0125 Mhz. The third is 150.0250 Mhz. And so onthrough 173.9750, 173.9875, and 174.0000.Your frequency will always start with a "1" - so that is pre-programmed for you. And the last digit in your frequency will bedictated by the second last digit, and the program will select thatlast digit for you as well.So, with a 7 digit frequency (xxx.xxxx Mhz) - and the first andlast numbers programmed for you (Dxx.xxxD Mhz) - you willonly have to enter 5 digits.The first programmed digit (tens position) must be either a 5, 6,or 7. The second (ones position) can be any number. The third(1/10th position) can be any number. The fourth (1/100thposition) can be any number except a 4 or a 9. And the numberyou select here will dictate the fifth number you are to program.
Program a 0 or a 5, your next number must be a 0. Program a 1 ora 6, and your next number must be a 2. Program a 2 or a 7, yournext number must be a 5. Program a 3 or an 8, your next numbermust be a 7. The previous list of examples shows this clearly.And the 'last' digit in the frequency (1/10,000th position) will bedetermined by that second last digit. If the second last digit is a 0or 5, the last digit will be a 0. If the second last digit is a 2 or a 7,the last digit will be a 5.After you enter your valid 5 digits, the cursor will move to thenext line, similar to the following screen shot:At this point, the program is awaiting another instruction fromyou; either an f, v, c, or s. (Remember: c or s are only validentries on scrambled units.)FOR SCRAMBLED UNITS:At any point in the sequence where the program is awaiting aninput instruction, you can set the 'scramble' or 'clear' mode bytyping sv ("s" sets scramble mode, plus the "v" verifies theprogramming) or cv ("c" sets to clear mode, plus the "v" verifiesthe programming).9.) After you have finished validating your entries, turn off yourtransmitter, disconnect the cables, and close the computerprogram.Here is some information on INVALID frequencies:If you enter an invalid frequency, the software will respond onthe screen as follows:
As you can see from the example, the frequency entered was158.9685 MHz. This is invalid per the rules. The softwareresponds with a comma, then 6 zeros, and a carriage return. At thispoint, the program has not updated your transmitter, and isawaiting an input instruction (f, v, c, or s) from you. Enter an fso that you may re-enter a correct, valid frequency.Programming from a Citation 20 Receiver/Recorder KitPlease consult your Citation 20 Operations Manual for directionson programming transmitters directly from the Citation 20,WITHOUT a separate computer!
The Joey's solid state recorder has been designed by GeonauticsInternational, an Australian Company, who is widely known in theelectronic surveillance field for their well engineered devices. Therecorder used in the Joey comes from their Whisper line ofequipment, and is a modified version of their A1 Whisper Tag.The Whisper software package is used to control and download theJoey Recorder. The program also offers limited playback featuresthrough the standard Windows multimedia player.INSTALLING YOUR RECORDER SOFTWAREThe computer program supplied to setup, playback, and maintainthe recordings you will make with your CTR-751 transcorder is amodule written by Geonautics for their stand alone Whisper line ofrecorders.

Locate the GEONAUTICS selection and point to itwith your cursor.d. Left click your mouse on the selection titledWHISPER.
RECORDING AND PLAYBACKNOTE: If the REC programming/download cable is connected to theJoey, recordings can only be initiated via the Whisper Playersoftware.Each time power (or a short) is applied a new FILE number andrecording will be created on the device.Configuring the recorder for operations - programming1.) Connect the CTR-751 REC programming/download cable to thetop of the Joey via the 6 pin connector. This connector is keyedfor proper installation. The cable will be marked with a "REC" -indicating it is the cable for transmitter programming.2.) Connect the D style 9 pin female connector to an open serialport on your IBM compatible computer. If your computer's serialport is a 25 pin connector, you will need to use a DB25 to DB9serial adaptor (not included).3.) Start the "Whisper Player" software.4.) You must know the number of the Serial (Com) Port you haveattached the Joey to. The software comes ready to work with Com1. If you are using Com 2, 3, or 4, you must select that port via the"Serial Port" area of the software. Your serial port should beconfigured for a data transfer rate of 115k baud.5.) Apply power to the Joey by attaching a 9 VDC battery to thebattery connector found on the REC programming/download cable.Once power is applied, the Joey and the software will 'handshake'.After about 10 seconds, the software will report that the Joey isONLINE via the following response: $WSP, ONLINE. You willsee this in the Whisper Player Communications Window found inthe lower left corner of the software screen.NOTE: You must wait for the Joey to report that it is ONLINEbefore you can continue. If the unit does not report, disconnectthe 9 VDC battery, wait 5 seconds, then reapply the power to theunit.6.) Press the "LIST" button to see if the recorder has filespreviously recorded on it. If the Joey has files on it, yourcomputer screen will look something like this:
Listing progress is reported in the Communications Window.7.) If there are files on the device and they have not beendownloaded, and you want to save these files, see the section onDOWNLOADING8.) Select the "Sample Rate" and 'Quantisation" settings. Thesecommands change the "free" recording time available.A "Sample Rate" of 8kHz captures 4kHz voice which is roughlyequivalent to telephone quality. Alternatively the full voice rangeof 5.5kHz can be reproduced using the 11kHz setting."Uniform" quantisation provides the best quality as it stores eachvoice sample independently. The "Non Uniform " setting uses alogarithmic scale to store delta differences between successivesamples which increases the record time with only a minimalquality decrease.How to make a recording from within the Whisper Player SoftwareTo make a test recording, ensure the microphone is attached to theJoey, and select "Record". De-select "Record" to finish therecording. The listing is refreshed automatically at the end of therecording. Use the "List" command to refresh the list of recordingsmanually.NOTE: Recordings with a duration of less than approximately 10seconds will not be shown in the directory listing.The lines of information on the recorder file listing gives thefollowing information about each recording:a.) Sequential Number - each file on the recorder is given anumber in sequence which serves two purposes. First, the uniquenumber gives individuality and identity to the file. Second, thenumber tells you how many individual files have recorded withthat device. Your brand new Joey will not start with file number1, because files are created during the manufacturing and QCstages of production.b.) Time - duration of the recording, listed in real time.c.) Quantisation setting for that recordingd.) Sample Rate for that recordinge.) File size for that recording in kBytes.Once the files from the Joey are "LISTED", then you candownload and save them, and you can clear the recorder forfuture use.How to Download and Save files1.) Set up your Download Path. The Download Path tells theWhisper Player Software the location it will place the file afterthe download.a. On the Command Line at the top of the softwarewindow, left-click on PATHb. Select DOWNLOAD DIRECTORY, and choosewhere you would like your files downloaded to.c. Your Path will be displayed on the bottom of thesoftware window. This Path will be maintained by the WhisperPlayer until you change it.NOTE: It is recommended that downloads are burnt directly toCD using suitable software such as Roxio's Direct-CD package
available from www.roxio.com. (In Windows XP, you can simplyselect your CD-R drive for downloading).2.) Select the recording to be downloaded by left-clicking on thefile identifier in the List Box. "Ctrl and Shift" keys may be used tomake multiple selections for downloading.3.) Once the files are highlighted, press the DOWNLOAD buttonto begin the download. You will see the software report it'sprogress to you in the Communications Window. The file(s) will bedownloaded and immediately saved to your PATH.Single files can be downloaded by double clicking on the recording inthe list window. Double-clicking starts the download automatically.Information on SAVED FILESThe Joey's Saved File Naming Convention utilizes three variablesthat make up the automatically assigned file name:1.) The "Prefix" - assigned by you the user, and is used to identifythe recording. The Prefix can be any combination of letters andnumbers, and is commonly your Casefile name. You assign theprefix PRIOR to download via the box near the top middle of theWhisper Player Software. Type in the name of the prefix youwant the saved filename to have, THEN download the file. If youleave the prefix window blank, the filenames will NOT have aprefix.In our screen example, all the saved files would have a Prefix ofTEST2.) The Joey's ID number - this number is unique to your Joey andcannot be changed by you. This is NOT the Joey TranscorderProduction Serial Number, but is a special number assigned to therecorder only.3.) File Number - this is the same sequential number as you sawnoted in the LIST command.Three separate and distinct files are created for each download:File 1: prefix.joey_id.file_number.imgThis is an image of the memory stored in the Joey recorder.File 2: prefix.joey_id.file_number.txtThis is a text report detailing the authenticity of the download.File 3: prefix.joey_id.file_number.wavThis is the Windows(TM) WAV file - this is the audio playbackfile. The downloaded WAV file can be played via the CD-likemultimedia controls found in the Whisper Player Software, or byany WAV file player, such as the Windows Media Player suppliedby Microsoft.Playing back your downloaded filesThe Whisper Player Software has it's own 'player' built right intothe software.1.) Press the BROWSE button. It will open the file directoryspecified by your PATH setting. From here, you can open
downloaded and saved recordings, or explore your computer to findother WAV files for playing.2.) Double-click on the WAV file you wish to playback. The nameof the file will appear in the box to the left of the BROWSEbutton.3.) There are three controls on the Player:> - select for PLAY, de-select for STOP|| - select for PAUSE, de-select for CONTINUE|<< - select for REWIND TO BEGINNINGNOTE: A single downloaded file, or the last downloaded file in alist, is automatically selected for playback.Clearing the memory of the JoeyOnce all required files have been downloaded, use the "Format"button to clear the entire recorder.NOTE: Individual recordings cannot be erased.WARNING: BE SURE YOU HAVE DOWNLOADED ALLIMPORTANT FILES BEFORE USING THE FORMAT COM-MAND. THIS COMMAND IS NOT REVERSIBLE.Closing the Whisper Player SoftwarePress the DONE button to close the software.File IntegrityTo ensure validity of the recorded data sets and to safeguardcontinuity of evidence, the Joey Recorder implements a numberof integrity checks.1) Each Joey Recorder is given a unique UNIT ID at the time ofmanufacture. The UNIT ID cannot be changed by the user.2) Every recording made by the Joey is given a unique FILENUMBER. The FILE NUMBER is generated by the Joey andcannot be nominated by the user.3) Recordings are made from blocks of data. Blocks are totallyself-contained and represent between 0.05 and 0.1 seconds ofspeech, depending on "Sample Rate" and "Format" settings.Consisting of 528 bytes, the block contains a 512 byte "datapacket" and a 16 byte "header packet". Each block is given acount or SEQUENCE NUMBER, starting at 1 for the first blockof each recording, and contains a CHECKSUM for the "datapacket" and a checksum of the individual packet CHECKSUMS.Each and every "header packet" also contains the UNIT ID andFILE NUMBER.Thus each 0.05 to 0.1 seconds of recorded sound packets can beshown to have a valid checksum, belong to a unique recording ona unique device and be in sequence with its neighbours. Thesecond CHECKSUM of the packet CHECKSUMS furthervalidates the integrity of the data. If a corruption occurs orintegrity fails the exact time and span of the dubious data can be
IMPORTANT:1.) If computer interface is not COM 1, you must select thecorrect Com port as described in the instruction.2.) The transmitter must be ON and powered in order to programit.3.) Turn OFF the transmitter when finished programming.OPERATING NOTES:1.) Antenna should always be kept vertical for best operation ofthe transmitter.2.) PLEASE always use fresh batteries at the beginning of eachoperation.3.) Check operation of transmitter portion of Joey with areceiver prior to any field ops.4.) Practice with this piece of equipment prior to use.readily identified.All this information is stored as part of the Geonautics' AudioImage (*.img) file and can be easily reconverted to a WAV file forlistening.
