Very nice site. Thanks for the graphs of your soundcard. Very informative. Please edit your PSK31 link. It has an extra ".PHP" so it won't work unless you delete the extra .PHP. 73 Craig KC2lfi

Dear Friends, My New Year's resolution effective immediately is to write human (including myself) readable software. I am so tired of looking back at something which I wrote two years ago, and having

Got my Softrock 40 up and running with the minimum of fuss, but some mega serious problems with the sound card producing spurs. This was a function of the soundcard (not the Softrock). I've done a

Thanks to KD5NWA I2PHD and KY1K for the comments The ICS501 is used in the Time Machine by ESS for their crystal osl, and I think it might be a fun way to generate some RF. With the Mim Order and

Good Afternoon All, This afternoon I have been running a v4.0 SoftRock40 using Rocky 1.2 and the mother board soundcard. On the same PC and at the same time, I am running v5.0 SoftRock on 20 meters

They have it for about $1.50 or less in qty 1 < http://www.nuhorizons.com/ > The ICS601 has better specifications, in terms of phase noise and it's about $4.50 Cecil Bayona KD5NWA www.qrpradio.com I

With 25 ps jitter, would that be suitable for a receiver clock? I seen it used to generate the carrier for a 2 meter transmitter. Cecil Bayona KD5NWA www.qrpradio.com I fail to see why doing the same

Bill -- The machinery to do this is already in the DSP code. As with a number of other things, what's missing is the ability to configure and control them as desired from the PowerSDR console. I'm

But, if you must have it, America II Electronics has 250 in stock, Quest Components has 4000 in stick. I actually wonder why a 74AC04 wouldn't work just as well.... GL to all. Art

Does anyone know where I could buy a couple of the ICS501 IC'S see www.icst.com/datasheets/ics501.pdf This ic may work well as a crystal oscillator for the SoftRock series of radio. The only source

The SR-40 has done its' job:-) I would like to purchase a previously owned SDR-1000 for myself for Christmas. I am interested in either the 1W or 100W radio at any revision level. No other options are

Hi Fred, I also use Delta 44, but I have never experienced a problem like this. I have played with the M-Audio control panel - tried to lock the sampling rate, to enable Reset when Idle, etc., but

I am so impressed with VAC, it is almost surely possible to do this. I had not considered this as a possibility but it could be done. After months of begging for an answer, when we finally adopted

Bob -- I'm assuming the easy change you're referring to is to display 40+khz spectrum in PowerSDR? A more interesting (to me) change would be to be able to take the IQ signals from PowerSDR and pass

This is an easy change. We only need to say do it. Bob Mike WA8BXN wrote: -- Laziness is the number one inspiration for ingenuity. Guilty as charged!

Hi, I've install the X-tal for 30m band into the Softrock 40. As Bruce...<N1RX> said I changed two 100pF capacitors to 33pF and worked fine on 30m band. I heard many DX stations by this little radio!

Has anyone used an SDR-1000 with its normal software to control frequency but decoded the audio stream with Rocky to get a wider display frequency wise? Looks like the SDR-1000 software only provides

Good Afternoon, The latest v5.0 schematic is now posted in the files section. Component values shown on the schematic result in working v5.0 SoftRocks on 40 and 20 meters. Band specific components are
