Hi all, I have some basic questions but even though I have been using Linrad for quite a while I can t seem to find answers. Most of my issues are related to the I/Q signals.
My first one is: how does one get into the I/Q cal routine? Secondly, i am using a Time Machine with acceptable resuls for my application: microwave sdr, where quality is less of an issue in absolute terms but the pan display capability is worth gold. My intention is to replicate this setup for our contest station, this time using a few Softrock v7. I find that while the uncorrected I/Q Time Machines shows the image at least 30 dB down, while this is only about 20 using the SoftRock, that is a surpise to me. When using the Softrock with Rocky, the auto I/Q balancing works fine and the correction graphs show flat gain (to within a few %) but the phase goes from -20 degrees to +20 degrees, in a perfectly straight line from -22 to +22 kHz. This points to an error in my Softrock I presume but after extensive troubleshooting I have not been able to pinpoint it. Many thanks for any assistance, Xtof on4iy PS: using Delta 44 with Linrad, and generic card for Rocky. ############################################################# This message is sent to you because you are subscribed to the mailing list <linrad@antennspecialisten.se>.
