I installed the emu-0202 USB soundcard today and interconnected one of the LP-Pan which was connected to the main-RX IF. I used Spectravue as SDR sw since it was already installed for my SDR-IQ. I didn't run into many hurdles and had 20m being displayed at 96-KHz bw. It took a little getting accustomed to the display being relative freq. offset to the radio dial. Bonus is I have audio playing from my computer speakers again (via the direct monitor). I did discover that the SDR-IQ has the opposite convention for deciding I and Q input but was easily swapped in the sw (R=q, L=I on the LP=Pan while Spectravue wants them reversed).
It is also nice to have audio on my computer, again. Both computer sourced audio and the LP-Pan are mixed in the emu, so one would want to mute the computer when running the K3+LP-Pan. I noticed a pronounced bandpass curve in the noise leve which was pretty high (-62 dBm). I had to run the emu input gain at 95% full setting so wonder if that is normal? I haven't tried the other LP-Pan for comparison. I wonder if the passband is an artifact of the LP-Pan or the front end of the K3? I am kind of spoiled with the SDR-IQ which displays a flat spectrum. I have not tried LInrad as the SDR sw, though it is installed on my computer. I have the Delta-44 soundcard to install and second IF (sub-Rx) to make. But a good first step! 73, Ed - KL7UW, WD2XSH/45 ====================================== BP40IQ 500 KHz - 10-GHz www.kl7uw.com EME: 144-1.4kw*, 432-100w*, 1296-testing*, 3400-winter?
