Re: [Flexradio] Imagine digital starting at the antenna connector...
This could indeed be good news!! I have a Flex1500 and a friend's SDR1000, but have been avoiding the 3000 or 5000 for three/four reasons: 1) QSD/QSE balance issues. This stems from transmit issues with the old SDR1000. My spectrum analyzer made me gag. 2) Firewire. I loved it for broadcast video acquisition, but not so much for SDR. It's about as common as parallel ports, especially with laptops. 3) Pricing. I have a hard time buying a new radio at the cost of the 5000. Given items 1 & 2, it was not worth the hassle getting wife approval. 4) OS support. I would like to see Linux and/or MAC support as well as Windows. This may not be part of the new rig, however. An open, documented HW/SW interface would help, as Flex would not need to be the sole provider of SDR/DSP software. I regularly see questions about whether SDR software other than PowerSDR supports Flex rigs. Unfortunately, that could also bring up marketing and legal issues, including type certification of the hardware. I have played with DDC/DUC designs for a couple of years now, and am convinced that they are the future. Their main limitation seems to have been dynamic range, I believe Mitola and others have suggested a dynamic range of 130dB or better is required for HF. Given a good (expensive) 16-bit A/D and processing gain in the DDC, this is achievable with a careful design. Other than low-cost SoftRocks, I bought my last QSD/QSE-based rig a while back. I hope the new rig uses ethernet connectivity. I trust the new Flex box will satisfy my concerns 1 & 2, and therefore help me with item 3. I just hope the cost differential is not too high!

Re: [Flexradio] Imagine digital starting at the antenna connector...
Anything else? It would be neat if this new receiver was a module that fits into the existing 5000 case maybe as the rx2. Rather than needing a whole new transceiver.

Re: [Flexradio] Imagine digital starting at the antenna connector...
Television transmitters are like 6 MHz wide. Why couldn't a flex someday produce multiple signals in a wide pass band? We also need a transistor like device that produces 1500 watts out at 99% efficiency that costs $100. Someday we will have it.

Re: [Flexradio] Imagine digital starting at the antenna connector...
Sounds like Flex may be adopting a direct sampling approach similar to openHPSDR Mercury and Hermes. For anyone interested in details of direct sampling design, I can highly recommend the 2008 TAPR Digital Conference video featuring Phil, VK6APH describing the design of Mercury. See DVD #6 at: < http://www.arvideonews.com/dcc2008/index.html > If this is indeed what Flex has in store, it will be interesting t compare how they do it. Pete, N3EVL PS I have no financial interest in sales of this DVD.
