radiolink fine tune
« on: 2016-08-04, 11:20:15 »
Hello

I have setup a remoterig link between my house and our ed3x contest station

The remote side is in the middle of a rural zone
There is an internet connection provided by a radiolink.
The bandwith should be: 2mb uplink / 10mb downlink
At home I have 30/300 fiber link

Audio transmission is great
Audio reception is 90% ok but I n otece some short cuts every 10 to 15 seconds
I have been adjunsting jitter settings and this is the best I am able to obtain as far as I know
Current vaues are:

Audio quality: 2- Linear 16 bits 8 khz  (going to 0 -  Alwa 8 khz doesn't improves it)
Rx jitter buffer size: 10
Rx jitter delay: 3
Audio packet size: 20 ms

Both sides


Can you advice me about a nore "scientific" method of getting to the best situation?

I suspect that the "little" problem is caused by the jitter introduced by the 2mb uplink of the radiolink

Thanks  in advance

Marcel

when adjusting the jitter settings increase the jitterbuffer delay also to just lower than the buffer size

8 and 10 as example
