Hi Bob,
Is there a way to get at Tx I&Q DC offsets in your code. I couldn't fine any. Some of the SDR stations on the air have noticeable carrier present during SSB TX. Using a spectrum analyzer I've noticed that during TX image cancellation I can get the image 20-30 db below the residual carrier! After thinking about this I decided to measure the output of my Delta 44 sound card. It has offsets of -12.8mV on the I channel and -4.11mV on the Q. I would imagine some cards are worse. It would be sweet to null the carrier another 1,000%. 73, John -------------- next part -------------- An HTML attachment was scrubbed...
