I've done a writeup at

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.

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 to figure it all out again :-)
What brought this to the forefront is the Motorola/Freescale announcement of the 16 pin 8k MC9S08QG8 chip. This is going to be one gas of a new chip to play with, shades of the old MCD 4.0 keyboard with display :-) The "MC9S08__" series of chips have a Background Debug Module built in, even in the 8 pin 4k MC9S08QG4 chip. This means ease of development for all those fun small projects. Digikey tells me they will have them in their computer in three weeks, so I hope for parts by December, just in time for Christmas :-) Not only do you get in-circuit programming, you get exotic features such as breakpoint, single-step, trace, register readout, ram readout, etc. You can change your source click on debug and reload your chip in one step. I am looking forward to working with this chip.
Today I broke out an old MC9S08GB60 project which reads a Dallas Semiconductor DS18B20 temperature sensor and displays it in NTSC video on a TV set. This is a warm up for the new smaller chips. The MC9S08GB60 is a 64 pin LQFP package and difficult to mount. The new 16 and 8 pin dips will put the joy back in our projects. I actually generate the NTSC video sync pulses with a two bit D/A (two resistors on port bits) and a lookup table driven output compare interrupt. The GB60 is clocked by a 40 MHz surface mount canned oscillator. The S08 series buss clock is a divide by two, so we have a 20 MHz buss or video dot clock. These are 3.3 volt parts and I'm using a USB Multilink from P&E Mico for programming.This was a fun project dated Mar 2004. So that gets me back to my resolution.
Less is More... At the Saturday Ham fest, Smokey, K5RDJ, sold his MCD 4.0 with keyboard to a gentleman. They asked me how to change a mode and I couldn't remember how to do it. Someone else commented I had put too much in there (4Kb program) :-) They were right and I referred them to the Internet document. However it got me to thinking about these new $2 chips. With 8k and 16 pins I can add a display, or do an RS-232 keyboard/display terminal quite easily. So there's plenty to work on now :-)

Sorry about the dissertation, but it's putting the excitement back into programming.

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 writeup at

Hope the info is useful to the subscribers here....

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 shipping the cost
is not to bad compared to some of the DDS
VFO projects in the works, and the cost of
crystals from DigiKey/Mouser is doable.

After all the SoftRock40 Kit was $23, do I
need a $300 VFO.

Thanks Again

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 with a second instance of
Rocky 1.2 and the D44 soundcard. The PC is a fairly low end Dell with
a 2.2 GHz P4 processor and the CPU is running around 50%.

The v5.0 SoftRock/D44 is set for 96kHz sampling and so I am able to
see from 14.012 to 14.108 MHz. Very interesting to see both versions
of the SoftRock playing well together on this very busy SS test
weekend...many, many signals in view.

73,
Tony KB9YIG

They have it for about $1.50 or less in qty 1

< >

The ICS601 has better specifications, in terms of phase noise and it's about $4.50

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 that I have found has a mim of 96 peices,
which is a bit much for me to try out!

On top of that, I might not be able to even see the dang thing!

Any comments?

I fail to see why doing the same thing over and over and getting the same results every time is insanity: I've almost proved it isn't; only a few more tests now and I'm sure results will differ this time ...

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.

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 beginning to think a useful feature in PowerSDR would be the
ability to accept batched SDR commands in ASCII, since that's what the
sdr process actually sees anyway. That would allow a back door to some
of the occluded features for those who really need and want them right
now.

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....

Bruce,
consider carefully the use of that chip. While I haven't ever
used it, and so I can't speak from experience, I have been told
from knowledgeable persons that its phase noise is terrible, as
it is meant as a clock generator for logic circuits, and not for
analog applications where spectral purity is of utmost importance.

Hi Bob,

From what I gathered from posts made by the author of VAC to various
newsgroups in the past when he was developing the driver it appears
that VAC is the old NT Style type of driver.

The last progress I made on vSound was to implement a callback
mechanism to user mode using a user mode created event object. The
handle to the object is passed down to the driver via IOCTL and the
driver dereferences it into kernel space. When data is available
the driver signals the event that the user mode app is waiting on.
With this you now have a callback-like interface to the driver
similar to PortAudio. The obvious nice part of basing a virtual
audio driver on WDM is being able to use it with Ks.

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 still was unable to reproduce this.

When Rocky opens the sound card, it specifically requests the sampling rate selected in its Settings dialog, and continues only if the card agrees to work at that rate. It looks like your driver says OK to Rocky but then does not keep its word!

Please see if you can find a driver update on the M-Audio web site.

73 Alex VE3NEA

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 Virtual Audio Cable and the guy sold a couple of hundred copies in a few days, he woke up, figured out the source for the sale, remembered me, and finally answered my emails. He offered to generously let me use the source code. If only I would be so kind as to send him $5000.00.

Alex has been extremely kind and has allowed us to use his WDM-KS Delphi code without charging $5000.00. ;-) Because we will need to continue to use PortAudio to support things like VAC that do not know WDM-KS, or WDM period for that matter, we have chosen to take this generous offer and to fix the broken, non functional WDM-KS module in PortAudio as pay back to that project.

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 them along via VAC (or some other channel) to auxiliary programs such as Rocky, SDRadio, Spectrum Lab etc. Then one could run both concurrently (assuming enough computer horsepower) Would also have to do a bit of work on some sort of control interface -- would need to tell Rocky or the other downstream programs what the current center frequency of the IQ stream is etc.

Bill (kd5tfd)

This is an easy change. We only need to say do it.

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!
I feel its performance is the same with my K2 and better
than my FT920. hi.

It's a wonderful small receiver for two bands.
And I will try to modify the front-end BPF suited for 80m
band later...

Updated revised Softrock-40 to my website as below;



Some audio files are there...

Thanks for Bruce.
72/73!

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 for a 20 KHz window.
Thanks!

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 also
shown on the schematic sheet.

With the SS test this weekend, the Rocky panadapter display is very
busy running the latest 20 meter v5.0 SoftRock. The little guy would
be a pretty decent contest receiver with Rocky doing the heavy lifting.
