Thanks for the reply.
I've had a Flex radio Flex1000, since the first came out about 15 years ago. It covers 0-50MHz with a direct conversion receiver and 1 watt transmitter. I wrote the software to take the I and Q streams and process for the normal ham modes and take audio from the ccpomputer to transmit in a;ll the normal modes. I used a 2.4kHz IF implemented in the software to provide image rejection and higher order mixing products. It was a fantastic radio! Too bad I can't use it anymore. It requires a bi directionalparallel port for control and I haven't seen one of those for a long time.

I also have a Flex1500 which is also pretty nice, but not as sensitive as the 1000. It does all the DSP on an internal chip, so it isn't easy to get t oo the raw IQ signals! I've been in contact with Flexradio. I used to live in Austin, where they are headquartered, but There's no easy wat to get the raw signals like on the 1000.
As faras thr RTL-SDRDongles, I have one and it works fine with SDR#, but I want to do my own special processing. I asked about getting the raw I Qignsals on the Forumsand was told to look at the SDR# code, since it's open source, Unfortubatelt the uathor closed the project and withdrew the project from GitHub, so no luck there. I got the product sheets for the chips involved, but no useful info there either.If you have any other ideas, I would really appreciate it!
I want to get the dongles in bulk and write software for some specialized purposes. I've already done market analysis, but I need to get the raw I Q datato proceed.
