I would think that if you had a antenna hooked up instead of a 50 ohm load.. all the "spurs" you are seeing would be well below the band noise. They are all very low level..

this is a spur problem

imho, what you are seeing is not.

Also remember this is Beta software.

Hello,

I am running a new 1500 with PowerSDR v2.0.5 Beta SVN 3783

I ran both the filter and level test.

The level tests all passed however i still see spurs (in the waterfall) across 
all bands. See the following image:

http://moon-bounce.com/satcom/satcom_files/1500_spurs.jpg

The radio hooked up to a dummy load in this picture and during the filter/level 
tests.

Any idea why I am seeing these spurs? I have several other SDRs running that 
don't show spurs like this.

Also, in the filter test I had tests 4,5,8 and 11 all fail. Not sure if that is 
meaningful or what to do about it.

thanks,

Joe Steinmetz k6sat
