Got my QS1R today. Although I have heard of others having trouble installing it to a PC with Perseus, I decided to give it a try. Absolutely no problems at all! CPU load on my dual core 8400 processor is around 15% Perseus, 6-9% QS1R server and around 15-20% for the QS1R GUI (SDRMAX II).
What a wonderful new toy. Phil, I hope you have the recording function up and going soon.
More as I explore the QS1R, and compare it to the Perseus.
