I wonder what is going on, most people who write to me stating that
they don't see their entries or they have not been updated to new
quantities, but when I look they are in there with the correct
quantities. But then I hit the refresh button every time I go to the page.

This page is changing multiple times a day, if you don't refresh your
browser you will be looking at an old page stored in your PC instead
of the updated page from my site, that is how browsers work. My
browser is set to refresh pages older than one hour and even then I
have to hit the refresh button or I will be looking at old data, most
browsers the default is 24 hours so you might be looking at a page
that is a day old.

I just looked, your call letters and quantities match what you just
mentioned, so have you refreshed your browser?

Cecil,

I.ve refreshed my browser every time I've looked at the website. Up
'til just now, it kept showing me status effective the morning of the
29th, with 771 page views. Now I'm seeing status effective
03-01-2008 21:30 CST with 833 reads, but I don't see my name or call.
Are you still working through the spam-filed emails?

I mentioned last  night that while we figured out the buy someone
bought all the LP2985 chips from Mouser so they went from 1000 to 0 in stock.

I've spent most of the morning looking for a solution because they
have 500 on order, we need over 600 and they won't be in until the
middle of May, so waiting is not much of a solution. I have looked at
alternative sources and everyone is twice as expensive or they are
more expensive and don't have the qty on hand available. Mouser  has
the part in stock at a good price but in Qty 3000 reels and they
won't break them so that is out.

So I have been looking for a substitute and I have found one, that
has a reasonable cost (cheaper) and is available for shipping, it
also has compatible pinouts. For 99% of us there is no difference to
the other part but some may object so speak now or I will order these babies.

Company Analog Tech
Part number AAT3221IGV-3.3-2-T1
SOT23-5 with the same pinouts.
LDO 150ma 3.3V voltage regulator
http://www.mouser.com/Search/ProductDetail.aspx?qs=icbinUxoJoc47K5LmaaBHA%3d%3d

Strangely enough the 100 Ohm 1% metal film resistor is also a problem
since we have exceeded the available quantity and there is a very
long lead time (10 weeks), but I'm confident that I can find an
alternative source.

Send feedback only if you object to the voltage regulator
substitution to my personal email .

k5nwa @ sbcglobal.net make sure you remove the spaces or as an alternative
cecil.bayona @ sbcglobal.net

The other parts will be ordered  today.

Hi Ray,

I've received a pile of emails on this, here is the run down:

My setup is pretty simple.  I was using my 4 band softrock (2 rigs
combined); described in the files section under my call KF4BQ.  SW was
PowerSDR-sr40 (modified by Guido, PE1NNZ).
Keyline control thu parallel port (with transistor to invert with sw
closure to gnd).  Freq control thru serial port to radios Si570 and
PICAXE.  Sound card is EMU1212M PCI and on motherboard RelTEK HD.  Mic
is Icom SM8 that was already interfaced to computer for main ham
station thru a Rigblaster from West Mountain Radio.

All of these items are described in the file section.  Let me know if
you need more info on anything.

Hi All,
Is anyone successfully using an M-Audio Transit under Windows for SDR work?

Last year I purchased an M-Audio Transit for some SoftRock
experiments. Until this weekend I had only used it under Mac OS X with
DO8SEM's SDR application, and it works well there. At this point,
however, DO8SEM's program is receive-only. So this weekend I attempted
to use the M-Audio Transit on two different Windows systems with no
success. On a Win2K system I could not get the unit to work at all
after installing the driver. On a WinXP system the Transit works as a
regular sound interface but will not work with either Rocky or M0KGK's
software. Under Rocky I get a full scale display on the spectrum
display (solid green) with loud screeching noise from the speaker.
Under KGKSDR I get a memory access violation when attempting to use
the Transit. Much fiddling with settings never produced a working
configuration.

I am prepared to buy a proper sound card (maybe a Delta44 or EMU 1212
since these are known to work) but before I do I just wanted to check
and see if anyone has had any success with the Transit. I could not
find anything definitive in the archives other than the fact that
M-Audio used weasel wording when advertising the card's capabilities.

73,
Doug, K4DSP

Cecil,

 

We will need 10UF capacitors (2) at least should they be smt and also some decoupling capacitors. .1 is ok.

 

Also, it would be nice if someone draws a board for this parts  AAT3221IGV-33

 

I hope we can pay now.

 

Thanks for the group buy.

 

Regards. 

 

Jose Bonanca  (CT1aos)

 

I have the exact same problem you've described with the M-Audio Transit.  I
would like to use a USB soundcard so i can switch back and forth between the
Mac Mini and a Windows laptop, but I don't know what will work.

Looking at it after the fact I should have included the caps, the
volume versus 1 pricing is quite different.

10 uF radial capacitors at 25V which are quite useful in a lot of
things are $.04 in Qty 1000 that is dirt cheap.
.1 monolithic radial leads 50V is also $.04 at Qty 1000

I will buy buy some, keep a bunch for myself and make the others
available when I let the extra parts go on sale, but this is kind of
late in the game, still one would use  two pairs of each for each
voltage regulator and on extra set for the FIN1002.

I'm using a Creative Audigy NX-2 external USB and it handles 40M during this
weekend's contest ok.
Others reported that the Creative Sound Blaster Live! 24bit external USB
performs nearly as well as
the Delta 44 for about 1/3 the cost.

How much more is the LP2992 that was used on the SI570 board? It has
slightly higher current rating.

I have an 20M enhanced Softrock Lite listening on ~14000-14090 KHz with a
beta CW Skimmer program by VE3NEA that has Telnet capability.  From
1200-1400Z, beginning Monday, 3/3, if you wish to see if you are being
received at my QTH near Washington, DC, connect to 24.126.38.27:7300 with
your DX cluster client (any logging program should work), transmit your
callsign at least twice somewhere in that frequency range, preferably along
with a CQ or QRL?, and watch to see if you are spotted by the Skimmer.  It
looks for those "keywords" and for a callsign repeated at least twice, and
fading can prevent copy, so if it doesn't work the first time please try
again.  My stack of tribanders will be pointed toward Europe at that time,
but I should be able to hear most US stations as well.

This is an informal test of the reverse beacon idea.  It is likely, based
on CPU loading considerations, that a real reverse beacon capability
worldwide will depend on development of a web server capable of handling
multiple simultaneous user requests, but this is a first proof of concept.

Bill-

Quite well, but slower than expected.  I have it ported to AVR GCC now,
and it works on either parts that have dedicated I2C (TWI) hardware, or
parts that do not (i.e. bit-banging I2C).  It takes a different compile
to do either style.

The reason I needed to have it work on AVRs that do not have TWI
hardware is because the AT90USB parts typically do not have TWI.  I've
got most of the schematic done, and will be working on board layout
next.

Cost about 50% higher than the one I bought at Digi-Key but they only
have 270 and we needed over 600, Mouser does not carry them, they may
be cheaper somewhere but Mouser had an adequate substitute and they
are ordered.

The output current is not an issue, more current usage also means
better thermal sinking is needed which will be kind of hard for
something cobbled together.

It would be very nice to have this adapted for 6 metre beacon monitoring.  But
then distortion from aurora may be too difficult for software to decode.

Interesting work John.  I timed my AVR (8-bit) code today, and the
timings are always close to the same, regardless of frequency.  Using
32 bit floats for all calcuations, the total time to compute and set
frequency ranges between 5.8ms and 6.7ms.  This was calculated by
doing a 1 Mhz sweep, 1KHz at a time.  I'm not sure if your readings
including setting the freq on the device as well- I'd be interested
in hearing.

I too am pleased with the quick calculation times- it will make
interfacing with an encode quite a bit smoother (although not perfect-
  there will be hiccups as the encoder interrupt fires.)

I had the same problem some years ago in an encoder driven system
I used an stack to log the encoder interupt with an up/down marker
so the ISR became very short. The main routine then evaluates the

Hi Reid, very nice performance from your AVR. I toggle a port bit during
execution so I can measure times with a scope. So those measurements I
posted are measured with a scope. The load time is about 1.23ms at
400kbps. I am very impressed by your calculation speed. I suppose the
AVR is RISC running about 20 MHz where as the Freescale is CISC with an
8 MHz buss. I like AVR, and the only reason for trying Freescale is the
debugger. Thanks for your input :-)
