Bruce, I have it running here on 30 now. Unfortunately the band is mostly DED just now...[g] Chuck Carpenter, W5USJ, Point, TX -|- Rains Co. -|- EM22cv -|- 72 es 73 50 years -|- 19 - K2OFN and 31

Rocky also won't start the Audigy 2 NX external USB card here either. Won't work with 48 or 96 Khz sampling, or if you set a second card as output. I get the same error message as Joseph. But looks

Alex, The program starts normally, I can see the main screen. It appears to be OK. When I move the cursor around the frequency 'readout' changes. When I go to 'setting' I'm getting an error: Access

Hello Rockers Built a SoftRock40 and tried the more common SW packs available for Win. Running winxp home on a 1.4 Centrino laptop with a SB audigy 2 NX (usb) With PowerSdr had to use 2048 blocks

Alex: This is just awesome. Thanks for sharing your work and your ideas. I should have thought of the autobalancing trick a while back since I regularly do this kind of statistical coherent

Alex, That is really neat. Running here on a Dell Inspiron 8100 with a sound card called ESS Maestro 3, 48 kHz only. Lots of signals with a RTTY event going on just now...[g] Thanks. Chuck

Wow -- impressive. Fired it up with a USB Extigy and it works great. Will have to try it with the Delta44 and 96 khz sampling. Very cool on the automatic IQ correction. Will have to look at adding

I do have the program running with the on-board soundcard now. The usb soundcard is full duplex with usb 2.0 , so I don???t know what the problem is there.

Very nice software, I like the way it's so easy to tune around. I made the window the whole width of the monitor but not very high, and I could see a huge chunk of the bandwidth with out the CPU

Hi John, Your USB card may not be able to work in the full duplex mode at the highest sampling rate. According to the manufacturer, "Due to data transfer limitations of the USB 1.1 connection, it may

I have just released Rocky, an SDR program for SoftRock40. Rocky is available here: http://www.dxatlas.com/rocky/ 73 Alex VE3NEA

I know this is OT (slightly)...sorry. I have been looking at L/C combinations to allow LF to HF operation of the softrock. I'd like to have my softrock tune from 100 Khz to 15 Mhz. Making a wideband

How about using two of these in series, with some kind of buffer between them? Then we could use the daughter board all the way up to 30MHz :-) 73 de Anders, SM7TJC KD5NWA wrote:

After making my comment yesterday, I took a closer look at the SoftRock40 schematic. It is indeed connected as a ripple counter (Q from stage 1 goes to the clock of stage 2). It is possible,

Hello Tony Version 5 sound very attractive indeed, please count me for 1. Thanks, best 72/73 F5OQO Jean-Michel

Are you sure you know what a ripple counter is? A ripple counter is made up of multiple D Flip Flops coupled one to the next. Both ripple and synchronous counters use edge triggered flip flops but of

The 74HC74 is a synchronous dividor, NOT a ripple counter. If the /Q was connected to the clock of the next stage, it would be a ripple counter. Changing the D input does not change the output

You can also use a DDS or crystal oscillator running at 2X and put it through a diode doubler that feeds the comparators to turn it back to clean 74HC levels. Here is an example by Bill Tracey; <
