Pumping audio

[Kari SM0HRP]

I have installed RRC client on old laptop with Win 7. I can establish contact and controll with TRX-manager an ICOM 7600. But the audio is "pumping" at 2 Hz rate like a disturbance in earphone. Is it the audio stream to rapid for this Dell 630? Speaker LED bar shows 10 segments.

Hej Kari,
if I remember well is only matter to increase the packet buffer size. I'm sorry but I have not here my RRC Client so I cannot tell you the exact name of the parameter: as default is 20 but you must set it to 40 and the pumping effect will disappear.
Happy new year and good remote DX !
