My Allstarlink node key up every 20 seconds repeatedly?

Problem Summary

I am running an (new) AllStarLink node using an AURSINC SHARI interface on a Raspberry Pi 2B.
The node keys the transmitter repeatedly every ~20 seconds, even when there is no RF activity, no connected users, and no intentional linking.

This behavior occurs while the node is idle and results in periodic TX key-ups with a short beep.
It even ke-ups when i reconfigure it but with no beep?

;unlinkct=ct2
;remotect=ct3
;linkunkeyct=ct8

Please help me? I cant connect to a hub couse of the problem!

What OS are you using? ASL3 isn't supported on a Pi 2.
