Re: [Flexradio] Just how much DC Power Supply sag is acceptable?

This may sound nuts, but if the problem is on the power supply side, as far as not being able to keep steady voltage during the large current draws, why not take a tip from these nuts that run 6 gazillion watts of power in their car audio systems: put a whopping 1 farad cap between the power

Re: [Flexradio] Time for an upgrade!

You'd think that two processor cores running side by side would surely be faster than a single core right? And four cores working simultaneously would certainly run circles around it? Well no, only if the application that you are running is multithreaded and thus can take advantage of the extra

Re: [Flexradio] Time for an upgrade!

I've been doing some further reading on the subject and I think my original post is incorrect. The statement about 99% being written to run on one processor is the most confusing, because it fails to allow for HyperThreaded single core processors. I am not a programmer, and have waded out past

[Flexradio] One problem solved, another arises

Turns out I did have a VERY noisy power supply in my PC. Different PC, different power supply, noise all gone! But now I have a new problem. I can't hear any signals. I hear the same noise floor even if the unit is power off. Hooking up an antenna seems to have no effect. I tried the thumb

Re: [Flexradio] new to SDR-1000, computer-noise redux

Thanks Gerd, I will try to locate just such a power supply. Jacky, KA4HRE -Original Message- From: Gerd Loch [mailto:[EMAIL PROTECTED] the better solution: use a high quality psu instead of chinese scrap imports. Most of them have no mains filter at all. I have tested and can recommend

[Flexradio] new to SDR-1000, computer-noise redux

I’m sure this is a very old and very well addressed topic, so if the vets can just point me where to look in the archives, I’ll get to reading. My problem? Extreme noise from my computer prevents me from hearing much of anything. The noise exists even with only the power cable connected and the

Re: [Flexradio] new to SDR-1000, computer-noise redux

Thanks Carl. Someone else questioned the power supply as well so this sounds like a good direction to explore. Jacky KA4HRE -Original Message- From: Carl Vangsness [mailto:[EMAIL PROTECTED] I found that two Corcom 15 ET1 line filters in series with the AC power cord to the computer
