We need help! I have similar questions as Luis. I'm using a simple home built SDR feeding I/Q to a sound card, HDSDR output to a virtual cable (VB Cable). Do I need to worry about sample rate correction on VB Cable? If so is there any way to do it? Do I need to worry about sample rate on the sound card which is receiving I/Q from the SDR? If so, is there any way to do it? Both left and right channel are in use. What about time stamping? There are some delays I think in HDSDR. I don't know if there is any way to work around this. I would need a more stable LO for the SDR than its present crystal oscillator! I still don't know how to do this at reasonable cost. I suppose it will require a GPSDO which could output 450 kHz or something around there, but I have no practical idea how to do this. The more I read, the more confused I become. By the way I have a HP 3325B. Is this of any use for either the receiver LO or for transmitting EbNaut? It has the internal high stability option but I assume this is nowhere near good enough. It can accept external reference at 1 or 10 MHz but I do not know if this can make it good enough for anything. It also has a Phase mod input, but I know nothing about this. 73, Paul N1BUG
