Re: [Flexradio] Audio processing advice with the Presonus FireBox

Tim, There is a reason that many people recognize the Cubase software name. They are simply at the top of the game. You can use the version that ships with the PreSonus Firebox in combination with the PowerSDR software for fantastic results. The only con I can think of in this setup is that it

This is cool. It's great to be able to discuss the nuances of what really goes on within our radios. Spreading the word is a very good thing. I checked out John's(N8UR) web site and I'm inspired. I have an E5052A Signal Source Analyzer setting here and plan to make a few measurements. Here's

Great plan, John. I only had access to the 5052A for a day, so was pretty limited in what I could do; it's great that you'll be able to carry things forward. The one addition I would suggest is that you duplicate the DDS output measurements using the 10MHz source as well as the VF

I should have mentioned when I originally posted this that care needs to be taken to make sure that the Cubase software does NOT use the same output channel as the PowerSDR software. Not taking proper precautions here could cause the full output voltage (~6V) to be put into the radio which will

The DDS does in fact divide the clock down. Let me give an example. To make it easier for me to explain, let's take the case of outputting a square wave. In this case the phase to amplitude lookup table has the first half of the table filled with ones and the second half filled with zeros. Now

OK folks. I got my Firebox today, used the quick start guide and got it working in minutes. No problems. I loaded CuBase, didn't even open the application and when I try to run PowerSDR (any flavor from 1.44 up) I get a fatal error. It fails at the point where the splash screen says

Sorry I couldn't join in the fun; just too many things going on. TVB's PIC divider is a really elegant hack, and works very well. I'm currently working on a project for TAPR for a universal divider (to take any common frequency standard output and drop it to 1pps) and started out planning to use
