Sdr v1

I have little or no knowledge of the computer side of SDR. Have built up receiver so far and it worked first time on 40m. The problem is I get diminishing strength carriers every 1 KHz to the right of LO. I am using SDSDR, a brand new USB lead with an additional solid screen, Win 7 including extio-si570.dll.

Any advice as it is spoiling an otherwise great project? John G3WCO

If you still see them after hooking up an antenna, make sure your power supply is 13.8V.
