               4.  REPEATER      Mode   a Full-Duplex repeater for bridging a Local 
                                         Repeater into Internet
 
  1. Install RIGBlaster jumpers.
     RIGblaster manual, (p.8 to p.10), install jumpers to match the microphone pin
       functions on your radio.                                                                            
  2. RIGblaster manual, (p.10), install jumpers for RTS control. 
  3. Cable radio microphone jack to the RIGBlaster microphone jack in the front or the 
       back of the RIGBlaster.
  4. Connect RIGBlaster power supply to RIGBlaster and plug into AC; (RIGBlaster does not 
     have an AC switch). 
  5. Cable PC Comm1 serial port to RIGBlaster serial connector, RIGblaster manual p.2.
       (If an ABCD Data switch is installed between PC and RIGBlaster, insure ABCD switch 
        is set to the RIGBlaster position) 
  6. Switch RIGBlaster AUTO/VOX to AUTO.
  7. Test: Boot PC... RIGBlaster Digital light will come on and radio will go to TX ... 
       and then both will turn off automatically. 
       (This Boot PC test, confirms: PC, RIGBlaster and serial cable are working).
  8. Cable Radio Speaker out jack (RX Audio) to PC LINE-IN jack.
  9. Cable PC Speaker out jack (TX Audio) to the RIGBlaster Audio in jack
 10. Cable RIGBlaster Audio out jack to PC speakers.
 
     Note: PC Setup: Internet Connection Firewall: Click Start > Control Panel > Network

             Exceptions Click EchoLink > EXIT
 
 11. Setting Audio levels & Modes:
                 Set RIGblaster Audio Level Control pot counter-clockwise (TX Audio)  
     Note: After switching from Single-User to Sysop you must close and restart 
                 EchoLink program and you may want to turn PC speaker volume low, but 
                 audible, for the next setup step Adjust the radio squelch (open) full 
                 Counter-clockwise.
 
         Transmit setup: (MUST BE IN SYSOP MODE) Click TOOLS > ADJUST SOUND > PLAYBACK:
                 Remove all MUTES. Slide all balances to the middle. 
                 Slide all Volumes to position 1/2;  
                 Slide LINE-In Volume to Position 1/2 (or before clipping is observed at
                   RIGBlaster, on an O-scope)

                 CONTROL: 
                 Select: LINE-In - Slide LINE-In Balance slider to the middle 
                 Drag LINE-In Volume slider to position 1/2.
 
                 Slide the VOX level threshold slider, 1/3 to the right
                 Set radio speaker volume to 1/2 (or before clipping is 
                 observed at radio's external speaker on an O-scope). 
                 Adjust radio squelch as you TX DTMF Commands from your remote HT; squelch
                 is adjusted correctly when DTMF Commands are displayed correctly on the

                 Indicator and Conferencing with EchoLink). Each Station requires 16Kbps 
                 Bandwidth upstream/upload. 
                 56Kbps is a misnomer; typically a 56Kbps (U.S. limits 56Kbps to 53) 
                 modem downstream/download at 45.2Kbps and may upstream a max 31.2Kbps 
                 on a GOOD NARROWBAND telephone circuit. Bandwidth is Asymmetrical; 
                 upload/upstream throughput is limited to 31.2 Kbps, due to Noise being
                 introduced by imperfect A/D (analog to digital) conversion. 3 to 7 
                 Station Conferencing is for DSL ADSL ISDN Cable modem BROADBAND not 
                 56Kbps NARROWBAND. When in Conference type .LURK to hide your CALL.

Critique: EchoLink - Modes
   1. Simplex Link Mode - allows a 2m FM HT operating on a local Repeater that is 
   connected to Internet, to operate with another HT, or other HTs,  also operating
   with a Repeater connected to Internet, also allows for HT to PC operation.
   2. Repeater Mode - allows a local Full-duplex Repeater to be interfaced into Internet 
      and also as a Simplex Repeater.
   3. Single User Mode - allows PC microphone & speaker to operate over Internet to a PC 
      microphone & speaker. 
   4. SYSOP Chat Mode - allows PC microphone & speaker to operate over Internet to a PC 
      microphone & speaker in SYSOP. 
 
The Simplex Link Mode alone, makes EchoLink worthwhile and should make all inquisitive
Hams, look into to its theory and application. It is a continuation in the transition from 
Hardware radios and electronics to Firmware microprocessor based radios and electronics 
to Software radios and electronics. I would choose implementing EchoStation over the
EchoLink Repeater Mode. Hardware Repeater controllers are old technology and should be 
replaced with EchoStation, why Rube Goldberg an interface; Adds to system complexity 
and increases single-fault-failure. The audio quality of Single User and SYSOP "chat" 
Modes are of great audio quality.
