How do I check my audio quality on AllStar and Echolink?

 

The answer is quite simple - Use a Parrot to check your audio quality!!

To check your audio on EchoLink and AllStar, use dedicated test servers (Parrot Nodes) that record and play back your transmission. For EchoLink, connect to 9999 the *ECHOTEST* node. For AllStar, use 55553 to enable Parrot mode, or connect to a dedicated Parrot node to verify audio quality and adjust levels. 

EchoLink Audio Check

• Test Node: Connect to the *ECHOTEST* server (node 9999).
• Process: The server records your voice and plays it back immediately, allowing you to check for distortion or low volume.
• Adjustment: Use the audio level meter at the bottom of the screen to ensure levels stay in the yellow range during voice peaks.
• Sysop Mode: If running a node, adjust input/output levels within the software. 
• Normal Method using Supermon:  3009999 = Connect.  3009999 = Disconnect  
• DTMF Method using DTMF in Supermon or Radio: *33009999 = Connect.  *1300999 = Disconnect
  

AllStarLink Audio Check

• Parrot Node: Connect to a known Parrot node, or use 55553 to enable Parrot mode on your current node.
• Calibration: Use the ASL-MENU to adjust audio levels.
• Levels: Aim for a 1kHz tone to produce 3kHz of deviation.
• Adjustment: Adjust RX/TX gain in rpt.conf (erxgain / etxgain).
  
• Normal Method using Supermon:  55553 = Connect.  55553 = Disconnect  
• DTMF Method using DTMF in Supermon or Radio: *355553 = Connect.  *155553 = Disconnect 

Troubleshooting

• If using a radio, ensure the deviation is properly set on the receiver.
• Check that your USB audio interface (e.g., CM108) is correctly configured.
• For persistent issues, verify that your microphone and computer audio settings are not muted or too low.
