Hi Dana,
You did not mention the setting of your RF control. Have you tried that at a high (> 100) setting? On earlier versions of PowerSDR, under the AGC pull-down choose Custom, then on the Set Up menu option, DSP, AGC/ALC, under the AGC column you can increase the Max Gain to as sensitive as you desire. When I first got my SDR-1000 two years ago, I thought that it seemed less sensitive than my other receivers. Then someone pointed out that the default AGC setting was chosen to reduce the noise level. All I had to do was change the parameter on the ACG and I had lots of gain. In the newer versions of the software, they created the "RF Gain" slider on the front panel that makes it easy to adjust.
