Setting optimizing for poor connections
« on: 2024-02-20, 10:37:51 »
I travel frequently and encounter very good, and very bad levels of internet connectivity. In most cases, dropout, latency and jitter are the greatest issues. I have researched the list archives attempting to define settings which can be manipulated to reduce performance issues caused by 'poor" internet service.

Given discussions on this forum, I have selected some of the setup parameters that may be manipulated to better tolerate internet based issues. I would be interested in learning what other forum members use for settings on these parameters. For example, Key delay ms [0-250] is defaulted to 80 in my initial setup. Recommendations on this forum have recommended using the maximum setting (240ms) for poor internet issues.

I do not have the technical expertise to understand how all the parameters below affect the RemoteRig remote station performance. Hopefully responses to this post will help me, and others.

Many thanks & 73 from Andorra

Hi

for low bandwidth connections

Audio Quality = 0 is best and no dual RX

Increased Jitter buffer delay and jitter buffer size gives better tollerance for Jitter

Audio packet size = 40 reduce the amount of packets and  reduce overhead which may be better, not proven

Increased Key delay  is important for CW--transmission

the other settings has no influence
