[quote author=”KC2IFR”]What is the best audio card to use with windows 7 for use with the AM radio processor. I am a ham radio operator that still uses AM.
Thanks,

The BEST card for use with either FM or AM is still the Marian Trace Alpha as it is DC straight and will not need to be calibrated. AFAIK, Windows 7 is supported although maybe not 64bit versions.. Next choice would be ESI Juli@
Rules for FM and AM are much the same for quality although there is no need to use a card capable of 192Khz, or even 96Khz a normal HQ 48Khz card will be fine but may need a small amount of calibrating.
PS. Don’t forget to disable the MPX output on the I/O settings to open up the AM specific menus..
