Audio dropouts
« on: 2016-12-21, 22:20:10 »
We have set up an remote station using an IC-7100 with a quite nice bandwidth (100 Mbit control / 50 Mbit radio end) but with a noticeable ping delay of a quite stable ~100 ms. However we are experiencing very annoying short RX audio dropouts. The TX audio doesn't seem to have these dropouts. From the manual I find three parameters influencing audio transfer, RX jitter buffer size, RX jitter delay and Audio packet size.
Any advice on what to change and the range?

Also should the radio end / control end or both be adjusted?

Hi
The Jitter buffer adjusts are done in the box which receives the audio. The packet size and codec settings are done in the box wich sends the audio.
The settings do not have to be set the same in both boxes but the samplingrates must be the same. If you select a 8 kHz codec in one box you must select a 8 kHz codec in the other also.
