Hi All,

In Transmit mode the relay starts chattering continuously inside my HL2 enclosure. The chattering frequency goes up and down 

What could be the probable cause and solution

Also, during the relay chattering High Swr appears on and off 

Presently using  a Dummy load only at the Antenna port of hermes lite

Relay chattering on Tx is often caused by network latency.  Check via multiple ping times to the HL2.  Any variance in ping times over 10 mS during Tx may cause relay chattering which transmits broken up choppy bad signals..  Can be a problem even over "fast" networks. Could also be a symptom of lost UDP packets. 73, Ron, N6YWU

Thanks all for the suggestion.
It's now resolved and the relay is Quiet now.

I reduced the sample rate to 48000 in VAC  - probably that is working, not sure does that make any sense ?
