There are reports that when linked to NS, audio echoes on VE1MTN. A technician has visited the site and found no apparent issues with the hardware.
One theory so far is that those who have dual receivers can hear this echo. Audio processing on the microwave routing system can result in audio reaching different repeaters at split-second different times. If you have two receivers (or a dual band radio) tuned to different repeaters carrying the same audio, it can sound like an echo.
If anyone has any further reports of echoing audio on the East Zone, please use the Contact Form to describe your observations. Provide as much detail as possible.
Thanks for your help!
