Today I set about to get my new sound card/K3/LP-Pan 2/NAp3/new shack computer working in harmony. Alas, it was not to be.
I've got the levels set correctly (thanks to Larry) and signals are apparent on the band. What is perplexing is what I have named The Blob (see attached screen shot). It is: on all bands; moves in Free Mode NaP3) and is centered around VFO A marker with about 1/3 of the Blob lower in frequency and 2/3 higher than VFO A. It makes me wonder if there is something in the IF signal from the K3 to LP-Pan. The S-meter on the K3 says it is S3-4 in the Blob. I've searched for a setting in the K3 that I've overlooked but nothing. It is so strange to see a symmetrical shape to the Blog--like it is being shaped by a filter. If this is true picture of the spectrum at my QTH, then I've got huge problems outside. The sound card is a U5 set to 192 Khz. Computer is a W7 64-bit. Turning the LP-Pan attenuator ON does reduce the amplitude but but does not eliminate the Blob. I had just completed a noise audit of the QTH and found some switching power supplies that have been fixed with cores. This picture, however, is much worse than previously so something has changed. Just want to rule out a K3/LP-Pan 2 problem. I'm going to cross post this on the Elecraft and LP-Pan reflectors. Any thoughts and suggestions would be greatly appreciated.
