[Elecraft] [K3] Using K3 for relative noise survey

[Jim Miller]

I have an RSP1 and it works well with the free software available to do
spectrum work. I particularly like HDSDR's ability to make long term
recordings.

However I found it of limited use on 160m due to AMBC interference since it
doesn't have much (or any?) front end filtering. I'm 30 miles north of
Baltimore where the AMBC originates.

I put a brickwall filter in front of it and it worked very well afterwards.

I've recently bought an RSP2Pro which has better filtering in it which I
hope will eliminate the need for the external filter. I haven't had time to
even plug it in yet.
