Or if you like the Italian bread, which I occasionally bake myself, 0xF0CACC1A :) I will stop contributing to this thread now since it is impairing the signal-to-noise ratio of this mail

Yup, I know the C320C31 - used them at GE back in 2008: as you say, quite fast, and cheap. And yes, 2^n byte length circular buffers: one of the most essentially elegant constructs in the whole of

Mitchel, I tried to operate my 50 watt PA on WSPR mode at full power. Both IRF510's failed. Hans reminded me that this amp is designed for CW with around 50% duty cycle. It is not designed to operate

Yes, that's true in the 16-bit world. 73 + 88 = FB is true in the world of hex :) jerry@... wrote:

Generally Ohms law is the rule. Add RF to that and its true but the numbers are now real and imaginary. Generally back of the envelope numbers set the ballpark and from there it is dealing with

Hi Mont, I have a cheap logic analyzer I bought on a whim. No idea how to use it! 🙂 I just received a complete 80 M kit, built the display, and put the header pin in upside down. I'm so dumb. I

Sharc? Whazzat? IIRC the DSP we were using was a TMS320C31. We didn't use any of the DSP features, it was just a good cheap CPU. They sent me to a 1-week seminar to learn about it. In the class

Whups, that's "current equals Power / Voltage". 100W / 9.05V = about 11A. To pull 11A out of a 9V source, we need a load impedance of 9/11, or about .82 ohms. The impedance ratio ( for one side of

I would also like to mention the Hakko desoldering gun. Heated tip with power vacuum pump inside. Works incredibly well. I desoldered a display 16 pins in 16 seconds. Pricey but you only have to buy

Had not considered flux as the dielectric in a homebrew capacitor...?

Thank you gentlemen, unfortunately resoldering hasn't solved the issue. Since che CPU is working (as it's accessible via ISP), I'm tempted to blame the display assembly, perhaps the rubber contacts

I've had good success with solder wick and RA flux. I also use a solder sucker once in a while.

Michael, Everything I’ve found about it is just minimal flux.

You can find the a Flux Capacitor in November 5,1955.

He just does trial and error method in his video. The only difference is doing it before you solder it in the board which I don’t like because the non zero chance of hosing up a trace during the

In keeping with several other replies to Pierre's topic here, I group I work with uses the 5351 in several of our projects but we don't use them in near the quantity that Hans @ QRP Labs does. When

Thanks for that story, Jerry. I know exactly where you're coming from on the subject of optimization. My story (and I'm not going to try to one-up you!) also includes assembly language programming -
