Sdr v1

[aythorpe]

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.

Excellent advice, has cured the problem. I still have other tuning issues but will contact later if I cant resolve them.
