Hi, Out of curiosity for implementing the digital circuits in gnuradio, I tried implementing nand D flipflop in gnuradio but stuck with it because gnuradio can't support loops. I'm attaching grc file of what I tried. Can someone tell me how to make it work. It can't. It's not a bug,

Bhaskar, Thanks for your effort on not only getting GNU Radio working on Windows but also providing us with the steps you took to get there. That could be really helpful to a lot of people. I have made a link on our WindowsInstall wiki to point to your email for other people looking for help.

Tom: What would you recommend if my data was recorded at 50M for about 15 seconds and I would like to double to playback time with a throttle. If I set the throttle to 25M, would that do the trick, or is it more complicated than that? I'm waiting for a new shipment of RAM, and once I have that I

I often speed up the playback of large recordings by adjusting the throttle only. In the throttle block, I just multiple the recorded sample rate by a factor (say 10) to get increased playback speed. Don't change any other blocks' parameters - just the throttle. Very Respectfully, Dan CaJacob
