Re: [Elecraft] SDR-IQ

George

I have a K3 s/n 3569 (factory built) which has RF Board Rev 3. I have also
checked inside the radio to see that the IF output modification has been
performed.

My experience with the SDR-IQ is also disappointing. There are signals that
I can hear on the K3 (up to S4 or 5) that I simply cannot see on the
Spectravue panadapter. This is despite me setting the SDR-IQ to maximum gain
- but maybe I'm missing something too.

I'd also be interested to hear from anyone who already has the Rev 3 RF
board and has SDR-IQ on the IF output working satisfactorily (i.e. can see
weak signals!).

Hi John, 

Having had an IC-756, I was sure I couldn't live without a band scope and so 
I hesitated and almost didn't get a K3. When I did get the K3 I immediately 
realized I had been correct in my initial assumption, so I began looking 
around for a solution. 

I was initially very disappointed with the performance of the SDR-IQ and was 
convinced it was something I was doing wrong. I was right, with the help of 
John, N1JM who sent me his ini file (and others who lent advice and 
suggestions) and some further hacking around; I was finally able to get the 
level of performance I had hoped for. Now I'm glad I didn't throw it out. 

I guess I've been spoiled and just like to know where the activity is 
without tuning or scanning... 

If you want I can send you my ini file off list. 
I had the exact same experience as you; I guess it doesn't come out of the 
box optimized for the K3... 

George...WA1NTA
