The first thing I built, basically to see if I could, was the USB synthesizer.
The Si570 is labelled

CAC000141G

D088Y814+

Am I right in thinking this one is locked

Hi Gang,
Can anyone tell me if this is a hi speed part please.

SI570
CA00001416
D07B5808

Just might build a sig gen if it is the high speed part.

thanks, Jim WY4R

Hi Mike,

Great news!!! This calls for champagne :-)

I will keep this Si570 for the UHFSDR project then :-)))))

Actually I may have another one hiding in my built SR v8.3.  I shall take a look
and extract it with my hot air gun, and then I can put two items on sale:

(1)  unlocked LVDS Si570
(2)  built and tested SR v8.3 without the Si570 chip

:-))))

Hi Alex,

That one is no good, send it to me !!!

Actually from my notes on the Si570 I have had, that one is probably unlocked !!

The last 3 digits are YR and week code.  Think the transition was around 813 or
so.  Might be off a few weeks.  I have some 742's that are unlocked and a 808
that is unlocked.  My 814's seem locked.

Those were the good days, sure wish I had more unlocked ones :))

Hi Cecil et al,

I have one Si570 bought way back when we first started to use them.

It is a BBC000141G, and the small print below it is something like (not 100%
sure as the markings are rather faint and tiny):

D0609804

Could this be an "unlocked" chip?

Thanks for any clues.

It was only when I saw the "control by usbsoftrock" button in CFG, I
decided to look again at Edson's sdr-shell docs. You get the impression
that it should all happen using the mouse.
http://ewpereira.info/sdr-shell/ for keyboard and mouse operation.

That's interesting to know for the beagleboard and using usb audio. I
need wxWidgets and wxPython for quisk to run, both proving stubborn to
build on the beagleboard, it's also missing jack_connect which I am

Great work all round and thanks to Edson, Andrew, Rob and all who have

An xp virtual machine with no virtual network interface would have only shared flash drives as a disease vector. If the win 7 or vista was secure, then nothing could wreck your xp vm and even if it did you could keep it from getting out. Additionally if your vm had only ham sw and no banking web site usage, there's nothing to steal...

As there is so much old software for amateur radio does it not make a case
to run a dedicated computer with XP?
I'm afraid Linux and Virtual Machines are not too easy to cope with. Then
anything secure and entertainment oriented may be left to Win7.

One work around with this is to use an outboard audio interface with its
own codec. The Henry Engineering Match Box II is such a device but is
relatively, very expensive. I used this with a Softrock V6.2 during the
recent SSB Sweeps and received 20 reports/19 sections on 40 meters in
less than  five hours of play total. I did not work very hard at it!
Really surprised at what the Softrock is capable of at average peaks of
500-600 Mv. The plus side of these devices is that they are not
dependent on any other drivers other than the one within.

I have seen a similar item in the recent QST that someone is marketing.
It looks like it might work the same but the article did not give any
specs with regard to sampling rates, bit size, cost etc. Will have to
research that one a little more. Supposedly these units will work with
all versions of Windows as well as Linux, though I have only used it
with Win XP..

Hi All,

I have received 10 orders for uhf-sdr kits, so the Group Buy will proceed!!

A couple of you are interested in ordering 2 kits....this is ok, but
please be aware that these kits are technically not in production and
might still have bugs.

The new uhf-sdrkits mailing list has been established, all are
welcome to join. However, to join you must make some sort of
appropriate comment or have your callsign in your email address. This
is purely an antispam tactic, I hate spammers.

The uhf-sdr mailing list will be the primary means of distributing
information about the progress of the development and the distribution of kits.

Group is at:

http://groups.google.com/group/uhf-sdrkits

Regards,

Art

Sometimes libraries a programmer chooses to use are found to have issues such as
not being threadsafe, or the developer dies/retires. If such a library was a
backbone in the application and a potential replacement forces a rearchitecting
of accomodate, that can bea daunting task for something given away free. Perhaps
certain methods used aren't amenable to managed code (.net)
In any case, gratitude is the right attitude.

The solution would be to focus on making it work in a virtual machine and
running it in the required os, or trying to run it through emulator in Linux.

Well, Brian, you have composed a 'keeper'! Thanks for the review of
Windows 7. It sounds as comprehensive as one might be able to construct
at this point in the release and I am happy to hear of the benefits you
outline.

On 'Rocky': The author, Alex, made a pretty firm statement nearly two
years ago that 'Rocky' would, "never be ported to Vista." So I think
that is that. He gave no particular reason but has reiterated the
comment a couple of times to my knowledge. I have no idea if he might
consider the possibilities with Windows 7 but at this point in time with
so many open source, voluntary software offerings, I suspect he may have
to consider a whole new application if he were to put time into a
revision. Perhaps there is enough such software in the wings already.

In any case I am in agreement with your complements for Alex's work and
free offerings to the SDR community. He has created a very nice ensemble
of amateur applications over the years. I have personally benefited from
most of them.

Again thanks for the Win 7 critique...

What seperates a developer from signed or unsigned code is a certificate that costs around $200 a year.

Of course, once an app is signed if the developer quits updating the app, the old version will still continue to run and install fine.

Are there specific pieces of software people would like to approach a developer about getting signed?

This is a big deal every 5-7 years for me. I run a medium sized IT department, and upgrading operating systems is a lot of work. The question is always - when? We skipped the first release of Vista, but began limited rollouts when SP1 was released. Once they got over the first few days of confusion about changes, most users really liked Vista. We've fully tested Windows 7 now, and it is now our standard OS for all new machines.

Over the next 2 years, we'll be aggressively trying to rid ourselves of XP. Yes, XP works fine, and new OS's don't provide significant performance or user enhancements. But - the driver models in XP, and the complete lack of priviledge escalation controls, make XP nearly untenable for us now. Despite running multiple virus and spyware scanners, and operating the latest Ironport malware intercept proxies, we still end up rebuilding several machines a week from virus infections, and XP is so vulnerable to them, it's just impossible to prevent contamination now. We have yet to rebuild a Vista machine as a result of virus or trojan problems. The VAC controls and driver signing in Vista make it a lot harder for a trojan to take hold in Vista or 7.

Over the past few years, I have seen precious few home machines running XP that weren't compromised. There are so many vectors to get into the machines now, it's impossible to block them all, and the scanning software lost the race to keep up years ago. A huge percentage of identity theft cases can now be traced directly to Windows XP.

With respect to Rocky, the author gives it away for free, and I can well understand why he might be reluctant to re-write the code to support the new driver model. Perhaps the libraries he uses haven't been upgraded, or it's just a ton of work. He's probably wise to put his emphasis on software that brings him a return. I just bought an external soundcard, which works fine in Winders 7. A small price to pay, to prevent the russian or chinese hackers from getting my credit card data (I do shop online).

As one of the many beneficiaries of VE3NEA's largesse, I can only say "Thanks a million" for supporting us with free software, and if he never gets around to writing for the new driver models, it won't diminish my gratitude to him one iota. I hope he does, but his status as "benefactor" is secured, in my book.

I doubt the cut points were intentionally just short of the ham band. The grading probably has to do with the upper and lower tuning limits on the 5ghz vco and/or partial defects in the dividers. It would be a way of maximizing yield by selling everyone parts that will meet their needs.
It could be supply problems related to C grade parts are a result of an increasing percentage of parts meeting A or B grade.

The point in enabling a range around 303-346 is that it covers 2X a 155mhz atm/sonet clock. For clock recovery on a bit stream some circuits require a clock at 2x or 4x data rate.

Does anyone know if they work around 606-692 mhz range? 1200 mhz range?

What seperates a developer from signed or unsigned code is a certificate that costs around $200 a year.

Of course, once an app is signed if the developer quits updating the app, the old version will still continue to run and install fine.

Are there specific pieces of software people would like to approach a developer about getting signed?

Hi Sid, Glenn, Rob et al,

Finally SDR-Shell works with usbsoftrock -d -a !!!! :-)


Sid's "arrow" trick did it !!!

Thanks for all the tips.  I needed -n3 -s with jackd to reduce the xrun so that
the audio does not break.  (Found out from some jackd documentation that
recommends -n3 for USB audio.  I'm using my USB sound card - SoundBlaster Life!
24-bit external USB.)

After setting the "initial" freq in the CFG box, I can tune up and down with the
left and right arrow keys.

The offset of frequency displayed in SDR-Shell is 12 khz from the "center"
frequency of the Si570.  (I know exactly what the center frequency, ie the Si570
frequency divided by 4, which is clocking the QSD stage in the SR v6.3 RxTx, as
I am using the Mobo v4.3 with the LCD display.)

So this is like the constant IF method of tuning, which is fine with me.

Thanks to all for your tips, and to Rob for writing the SDR-Shell branch!

73's

This is a big deal every 5-7 years for me.  I run a medium sized IT department,
and upgrading operating systems is a lot of work.  The question is always -
when?  We skipped the first release of Vista, but began limited rollouts when
SP1 was released.  Once they got over the first few days of confusion about
changes, most users really liked Vista.  We've fully tested Windows 7 now, and
it is now our standard OS for all new machines.

Over the next 2 years, we'll be aggressively trying to rid ourselves of XP. 
Yes, XP works fine, and new OS's don't provide significant performance or user
enhancements.  But - the driver models in XP, and the complete lack of
priviledge escalation controls, make XP nearly untenable for us now.  Despite
running multiple virus and spyware scanners, and operating the latest Ironport
malware intercept proxies, we still end up rebuilding several machines a week
from virus infections, and XP is so vulnerable to them, it's just impossible to
prevent contamination now.  We have yet to rebuild a Vista machine as a result
of virus or trojan problems.  The VAC controls and driver signing in Vista make
it a lot harder for a trojan to take hold in Vista or 7.

Over the past few years, I have seen precious few home machines running XP that
weren't compromised.  There are so many vectors to get into the machines now,
it's impossible to block them all, and the scanning software lost the race to
keep up years ago.  A huge percentage of identity theft cases can now be traced
directly to Windows XP.

With respect to Rocky, the author gives it away for free, and I can well
understand why he might be reluctant to re-write the code to support the new
driver model.  Perhaps the libraries he uses haven't been upgraded, or it's just
a ton of work.  He's probably wise to put his emphasis on software that brings
him a return.  I just bought an external soundcard, which works fine in Winders
7.  A small price to pay, to prevent the russian or chinese hackers from getting
my credit card data (I do shop online).

As one of the many beneficiaries of VE3NEA's largesse, I can only say "Thanks a
million" for supporting us with free software, and if he never gets around to
writing for the new driver models, it won't diminish my gratitude to him one
iota.  I hope he does, but his status as "benefactor" is secured, in my book.

   That would allow monitoring of the VHF High public service band, but
not 2 meters with a C grade device on my UHFSDR.!

   Almost like they deliberately blocked 2X 144-148!  I would assume the
LVPECL would be the same as the only difference is the output interface.

I investigated this some time ago, Robby's or the group search does not find
the thread.

A quick check on a later "C" LVDS shows it to stop at 269.42MHz and work
between 303.12 and 346.32MHz.
I seem to remember that I worked out that the on/off points related to
switch points in the chip showing various ranges had been disabled
internally.
Anyone having early LVDS is sitting on a fortune, I have 6 "C" grades which
seem to cover the whole range.
