[Elecraft] Poor man's pan adapter

[Don Wilhelm]

Ron,

I have not completed it yet, but the Softrock can make a good 
panadapter.  Be aware that the Softrock by itself does have local 
oscillator leakage and can feed back into the K3 IF if connected 
directly.  An isolation amplifier is needed in addition to the Softrock 
receiver.  Jack Smith of Clifton Labs has a Z10000 kit that will do the 
job nicely.   http://www.cliftonlaboratories.com/z10000_buffer_amp.htm
