[hpsdr] Mac/WinXP with Janus/Ozy question

[Joe Martin K5SO]

Hi Phil,

Thank you for your response.  No, I don't have to use my internal  
sound card/internal speaker; I can use an external audio amp/speaker  
connected to the Janus output port instead.  I was primarily confused  
as to whether my A/J/O boards were functioning properly with  
PowerSDR.  From your response it seems that they are.

Great!  That's what I needed to know.

Vy 73,  Joe K5SO
