SELECTING/PLACING INTO THE DR ACCESS FIELD.  I WAS ALSO ABLE TO USE THE DR
SCAN FUNCTION TO SCAN NEAR REPEATERS FOR ACTIVITY.  THE SCAN STOPS WHEN A
SIGNAL IS RECEIVED.  THERE ARE ALSO MANY WAYS TO POPULATE THE TO FIELD WITH
THE VARIOUS D STAR COMMANDS TO EFFECT REFLECTOR LINKING AND UNLINKING,

MOUNTING PLATE FOR HIDING WHILE NOT IN USE.  I WAS A BIT LESS HAPPY WITH
THE ADDED EXPENSE ALMOST 100 OF THE OPTIONS NEEDED TO GET MY OPTIMAL
INSTALL.  THE SPEAKER IS MOUNTED IN THE MAIN UNIT, SO I RAN A MINI AUDIO
CABLE FROM THE EXTERNAL SPEAKER JACK ON THE BACK OF THE MAIN UNIT TO THE
AUDIO INPUT JACK ON MY DASHBOARD TO PIPE THE AUDIO THROUGH MY TRUCKS STEREO
SYSTEM WITH SPEAKERS IN EACH DOOR PLENTY OF BOOMING AUDIO.  USING THE ID
4100A  I ENJOYED OPERATING THIS RADIO.  I RECEIVED FINE REVIEWS OF MY
TRANSMITTED AUDIO.  I ALSO PLAYED BACK MY TRANSMITTED AUDIO USING THE D
STAR ECHO FUNCTION ON A LOCAL D STAR REPEATER, AND I WAS HAPPY WITH WHAT I
HEARD.  I HAVE OWNED AND OPERATED SEVERAL D STAR RADIOS, INCLUDING THE ID
5100A, AND HAVE A GOOD UNDERSTANDING OF HOW THE D STAR NETWORK WORKS.
WHILE THE ID 4100A IS NOT COMPLETELY INTUITIVE TO LEARN AND USE, AFTER A
QUICK READ OF THE BASIC MANUAL AND WITH THE MORE COMPREHENSIVE 273 PAGE

ARE SIX PUSH BUTTONS.  THE V/M/CALL BUTTON SELECTS VFO OR MEMORY OPERATION
IN VFO MODE, PUSH THE BAND/BANK KEY TO CHANGE BANDS.  THE MODE KEY SELECTS
THE OPERATING MODE FM, FM N, AND DV DIGITAL VOICE AM FOR THE AVIATION BAND

AND AM N ARE AVAILABLE FOR RECEIVE ONLY.  THE MW MEMORY WRITE BUTTON SAVES
THE CURRENT OPERATING DATA INTO THE NEXT AVAILABLE BLANK MEMORY CHANNEL

CAPTURE KEY ALLOWS EASY, INSTANT TRANSFER OF A RECEIVED CALL SIGN INTO THE
DESTINATION CALL SIGN FIELD FOR ROUTING.  THE MONI MONITOR KEY ALLOWS FOR
LISTENING ON THE ACTIVE REPEATERS INPUT FOR ASSESSMENT OF A REPEATER USERS
SIGNAL STRENGTH.  THE QUICK/MUTE KEY OPENS A LIST OF OPERATING SELECTIONS
THAT ARE USED MORE FREQUENTLY THAN THOSE ON THE MAIN MENU.  THE QUICK
BUTTON IS ALSO PUSHED FREQUENTLY TO ENABLE EDITING, ADDING, OR DELETING
TEXT/NUMERALS FOR VARIOUS FUNCTIONS IN THE TEXT ENTRY MODE.  ON THE TOP
LEFT CORNER OF THE RADIO IS THE MENU BUTTON, WHERE A MORE EXTENSIVE LIST OF
SELECTABLE OPERATING PARAMETERS INCLUDING THE SET AND FORGETS IS WELL
ORGANIZED AND DISPLAYED FOR REVIEW AND CHANGES.  IT IS OFTEN USED IN
CONJUNCTION WITH THE QUICK MENU BUTTON FOR EDITING TEXT.  HOLD DOWN THE
BUTTON FOR A SECOND, AND THE CURRENT OPERATING DATA IS LOCKED.  ON THE
BOTTOM LEFT CORNER IS THE BACK/DR KEY, WHICH TOGGLES BETWEEN THE
