      Do you have the latest ATTiny firmware version?

However, the signals move about 3Khz in the direction I drag the mouse and then suddenly pop back to where they started. I will check with my oscilloscope later if the frequency out of the si570 is changing at all, but I can't see what I am doing wrong.

PSDR offsets the LO frequency by a set amount (usually 9kHz) to use a pseudo IF to shift any centre frequency spike and noise away from the tuning point.

If you start PSDR without the USB device present you will find the USB device is deselected (I have not tested with the latest version, but certainly true of older versions).

I don't see why it doesn't work since the driver is installed correctly, PSDR sees the USB on startup and I can see signals move when I manually tune in CFGSR. I just can't seem to tune within my 96Khz block by dragging the spectrum or tuning within PSDR.I must be missing something obvious....

When I do drag the spectrum, the signals move a few Khz then 'snap' back to the original position. Any ideas?
