What generates the nice 7.054- 7.056Mhz signal on the computer (PowerSDR or Rocky) when the SR-40 is not installed ? Excellent choice for the crystal freq, by the way. No sense having 2 large spurs. I

Hi Alberto, The switches used are two of the switches in a FST3126. I am needing to stay with this part for the v5.0 SoftRock to use a large supply of the parts I had to buy as part of a minimum

Hi Rein, Windows Driver Model (WDM) was first implemented in Windows 98, in a limited form, and it did not work very well. In the later versions of Windows WDM was significantly improved. I cannot

Bill, If you are using Rocky V.1.02 and still cannot see your soundcard in the list, please generate the WdmView log and send it to me. The log generator is at

Good Evening All, I am testing a two switch QSD circuit for use in the v5.0 SoftRock. The switches in the QSD are each on for 50% of the clock cycle and staggered by 90 degrees. All other circuits

Thank you Glen - and all others who sent me the WdmView logs. I made a few corrections to the code based on those logs, and I hope v.1.03 will fix the problems like the one you have reported. Please

How do I change the sampling rate? I don't know much about sound cards. Bill Alex, VE3NEA wrote:

Hi John, { Version 1.02 will start with this card, however, the sound is quite muffled and sound is distorted. Also, strangely enough, the program recognizes only one side of the cards input, or

Hi Bill, Try a lower sampling rate, it looks like your card does not support the parameters that you selected. I am working on wav recording and playback. The wav component that I wrote a few years
