Hi Jim, Feedback from Flex hasn't been very promising over the last year regarding a receive-only unit. My SDR-1000 was probably one of the last receive-only units they sold. It disappeared from their Web site shortly after my purchase in late 2005.
I certainly hope Flex reconsiders, as there are fewer and fewer new communications receivers on the market for those who have interest in the RF spectrum other than ham radio. Some of my MW DX friends have been very interested in the SDR-1000 over the last year, but they don't want a transceiver and/or Flex won't sell them a RO version. A receiver version of the Flex 5000 would be impressive, and appeal to receiver afficionados in the market for a WJ HF-1000, Ten-Tec RX-340, JRC NRD-302A, etc. I ran a blog for about a year, specifically to share my investigations into the SDR-1000 as a MW DX receiver and for "tropical bands" shortwave use. Check out: www.sdr-1000.blogspot.com. It's also linked from the Knowledge Base on the Flex-Radio site. I stopped updating the blog last December, as I came to the conclusion the radio is very worthy for MW DXing as long as you add appropriate low pass filtering. I may restart the blog in the future with info from my experience repackaging the SDR-1000, the low pass filters, and HPSDR Atlas/Ozy/Janus into a single enclosure.

I also find the flexradio an excellent DXing receiver, which makes me think there is a market for a similar receive only unit, built on a single board.
