Re: Softrock Image rejection build 277

Hi Simon et al...

Apologies been out of contact as leaving current job soon and daytime access is now severely restricted.
I'll be on Skype in shack tonight and tomorrow night.

I am melting solder on a MOBO V4.3 and Si570/SR V6.3 setup, with 4x20 LCD etc for you and will have that with me when visit just before Friedrishafen 2010 so you'll have that for Softrock TX development end June.

The image rejection issue...
As you know Rocky software etc does this as an 'in band' calculation sampling all the strong stations in the current IQ bandwidth so the image rejection gets better the longer the SDR is on the air. Which is what was implemented in the link you mention. By altering the phase and amplitude with SDR-Radio you can deal with image rejection for one specific hardware set up as we have already tested and that will reduce by 30dB any images but this is not always consistent when frequency changes (especially to another band). The same effect occurs with Rocky if you change frequency as well. The Genesis SDR radios have an interesting image rejection method that balances the I & Q signals through the RX op amps.

As the problem is Softrock specific it might be worth suggesting this is worth studying:
http://www.wb5rvz.com/sdr/RXTX_V6_3/image_rejection_hints.htm

A lot of image problems can be attributed to poor connections/constructions resulting in an imbalance in the IQ, poor leads and sockets can also be an issue. I have a couple audio leads with a 'ring' where the sockets have scored them.

The loosing USB connection during the process I have not seen yet. Loosing connection to a Softrock V9.0 seems to be an issue with the libusb driver & AVR Softrocks all seem to 'do this' from time to time if using Vista but not with XP, especially if anything changes on the USB bus (e.g. plug in a USB pen, or a USB drive goes to sleep). The radio will seem to work, then change bands and the radio carries on but the frequency hasn't changed.... I had not looked at this exhaustively yet so time to test needed. This does happen more often if the USB port is not a powered hub or a direct connection. I will have V9.0 and an Ensemble RXTX up on 40m and 80m.

Hi Alan,

I haven't really got the soundcard image rejection working too
well. I'll be working with Dom M1KTA very soon and together we'll get it sorted
out. I now have a SoftRock v9.0 and the Cross Country Wireless SDR so have all
I need for testing.

I am surprised that you lose USB control - I assume this is the
Si570 chip? I can test this myself, let me know if this is what you mean by USB
control please.

There's some excellent theory in Rocky http://www.dxatlas. com/Rocky/ Advanced. asp >which I must implement.

Simon,

Yes, I mean USB control of the Si570, it works until I open the image rejection panel and then is lost.
Perhaps you should leave that until others comment, I do lose this control occasionally with other software but it seems to go every time I close the SDR-Console image reject panel.

The actual image rejection seems to work well. The automatic in Rocky is excellent!

Thanks 73 Alan G4ZFQ

Simon,

I'm not sure how far you are with this. I've only just put v 277 on.

I find that image settings do not get stored.
After bringing up the image adjustment I lose USB control and have to
restart.

I presume these settings will also be relevant to the Server? I've been
running it for quite a while, showing Softrocks in a bad light, only the
basic hardware rejection.

Hi Doug,

I am aware that most people have managed to get the program to run with XP, but on the other hand I have been contacted by two others who have exactly the same problem as I experienced.

The only reason for trying to run it was to have the information to hand for providing support for the SoftRock firmware should any questions arise.

Like you I have my own preferences on what SDR programs I use, but do like to test the hardware with all available options for completeness.

Looks like you are low on CPU power, running PSDR on my 2.6GHz P4 (Win2000), it was about the same as you see, but the latest version on the 2.8GHz dual core (XP)it loafs along around 15 - 30%, so plenty of power left to run WSPR, internet access and email quite happily.

Hi Chris,

Both of Tony's designs you mention use exactly the same USB interface and v15.12 version of the AVR firmware from Fred PE0FKO that has already been proven with Simon's program using the SoftRock v9.0 RX.

I have both Ensemble boards here, and was involved in the original beta testing of the hardware for Tony, but sadly have been unable to prove either with Simon's program, as I have been unable to get it to work on either my Win2000 or Win XP PC's.

Win2000 fails to identify any sound card present.

WinXP recognised the Delta 44 sound card correctly but does nothing when the 'Start' button is pressed except report 'the radio is not runnig, press start'! The strange thing is the previous release did work before the USB / Si570 support was added.

It would be really nice if the Image Rejection parameters were retained across invocations of the program. (Unless, of course, they do already and I've missed something.) Thanks.

Help Me Understand

davidjmessing
 

With the Memorial Day Holiday, I have been spending time with SDR-Console and note taking.

I noticed the Frequency Spectrum Display preceeds the audio heard from speakers.

The Gray Bar of frequencies on bottom screen is shifted +100 kHz to the display of the Frequency Spectrum. Example, Frequency Spectrum is showing 3.7 to 3.9 with the Gray Bar indicating 3.8 to 4.0.

Water Fall Graphic appears to be about 2 kHz to the right of the cursor.

With LSB signals being received, it would seem the Water Fall and the Frequency Spectrum Display should show an asymmetrical image to the left of the cursor. It is like the Frequency Spectrum and Water Fall dislays are symmetrial as one would see in double sideband.

I may be not understanding the concept, and don't mind being told to re-think the process.

Thank you Simon for developing a fun product. You certainly deserve the honors from Dayton.

Thank you Pieter for a great piece of hardware, I can not praise SDR-IQ enough. Much value offered for the price.

I offer this only as constructive criticism. Lord knows I don't have the skill set to develop it any where close to what it now is. Consider me as the driver, not the auto maker. SDR has revitalized my interest in ham radio. Thanks for everything being offered!

It’s too bad you haven’t gotten sponsorship from Yaesu in addition to RFspace (you start looking like a NASCAR with a dozen sponsor stickers pasted all over). 

Seriously, I know I purchased a FT-950 and IF-2000 because you were making the SDR-Radio.com software to work with this combination.  I know others have purchased the FT-950 and IF-2000 for the same reason.  Having high quality software that works with your brand name/model radio – sells radios.  It is very easy to justify why Yaesu should sponsor you (to some degree) – then again, it is usually the competitor that goes seeking the sponsorship, not the other way around.  The two following articles from the Racing Secrets Newsletter I find helpful (true they do refer to race car sponsorship, but the ideas transfer over to radios).  It is interesting that there is a special column in each newsletter on sponsorship (obtaining, maintaining, and improving).

 

10 tips to keep your sponsor (advertiser) happy

by Phil Veldheer

 

1. Keep all the promises you made.

 

2. Promote your sponsors product or service to the best of your ability and believe in them.

 

3. Make sure you use your sponsors products or services if at all possible.

 

4. Send a list of your racing results, displays, promotions and future races at least every three or four weeks during the racing season. I do it every two weeks.

 

5. Thank your sponsors (advertisers) for their support and mean it. Show sincere appreciation.

 

6. Keep all financial arrangements confidential.

 

7. Come up with new ideas or new customers for your sponsor. Make sure your sponsor knows when you either sent them a new prospect or a new customer.

 

8. Don't do anything to embarrass your sponsor. They want a good representative for their company. Not a loud mouth loser. When you lose take it like a man. Go shake the winner’s hand.

 

9. Make sure your race car, tow vehicle, trailer and uniforms are spotless, remember you represent your sponsor and you want them back next season.

 

10. Don't wait until racing starts in the spring to see if your sponsor is going to "re-up" for another season. Get that all handled when the racing season is over in the fall. That way if someone drops off you'll have all winter to get another replacement. Live by these three words, "Do it now."

 

 

10 tips to help market your sponsor (advertiser) and make sure they renew next year.

 

1. Go to www.racingsecrets.com/article_racing-5.html (the article printed above) read it, print it, read it again and live by the 10 tips to keep your sponsor (advertiser) happy.

 

2. If you have an advertiser already that sells a product, lets say, Auto Glass, make sure that all your OTHER advertisers know what Auto Glass Company to go to. Got it? I sent my Auto Glass advertiser to one of my BIG Trucking Company and it resulted in increased sales for the Auto Glass Company.

 

3. Let's talk about promoting your Auto Glass Company again (we could pick any kind of company here). Come up with ways to promote sales for you advertiser. I developed a 6 to a sheet of colored paper-coupons, then cut them to size and passed them out to everyone. We gave free wiper blades away with every windshield replacement. Plus I got them in a lot of other companies’ weekly paychecks, I got them at the banks and credit unions in the area. I SOLD WINDSHIELDS! Do the same thing for your racing parts "advertisers". I picked up the biggest account for one of my racing parts sponsors. I picked up the second largest account for another one of my "advertisers" on my race cars in the last six months, it was fun doing it.

 

4. You want more exposure for your "advertisers", get your race car(s) in the next Memorial Day Parade, 4th of July Parade or Pumpkin Parade. Typically more people will see it at the parade and tell your "advertiser" than people who go to the races.

 

5. Get a perfectly clear photo of your race car(s) either sitting or action and talk to your local newspaper sports editor. Take with you a complete history of your race team, look professional and ask him to run a story of your race team, make sure the photos show the "advertisers" on the car.

 

6. Make sure you plan on having your race car(s) at your advertisers during the year at least once for either a coming picnic, special event or a special sale. Even think church picnic, you'll be surprised where you can meet new "advertisers".

 

7. If at all possible get tickets for your "advertisers" from the race track. I know our local oval track gives each weekly regular racer 25 free tickets for the season. Our local drag strip has new owners so we'll see what happens there.

 

8. Make sure the announcers mention the "advertisers" at the track. I have 48 ADVERTISERS on my 5 race cars and trailers and I have 53 PRODUCT ADVERTISERS on my 5 race cars and trailers. There is no way they can mention them all, but if you know an ADVERTISER is going to be there that day, MAKE SURE THEY MENTION that "advertiser". Get it?

 

9. Links on your website, this is simple, make sure you do it. Go to www.fastpistons.com for a good example.  Read some of the articles.

 

10. If you are reading this and can't believe someone has over 100 companies that either giving a person CASH or PARTS, it’s the TRUTH!!! Go to www.fastpistons.com and click on the link new the SPONSORSHIP COACH. I have over a year in writing this, plus 3 1/2 hours of audio that tells ALL of my secrets. This is the BEST MONEY you WILL EVER spend on your race team. It even comes with a double your money back guarantee. I have been racing for free and making a profit for years and could have easily quit my full time job four years ago and raced for a living.

There are two modes of integration:



1) Bandscope - the console works as a bandscope for the external radio by
connecting to the IF output.



2) Synchronise - the external radio and console frequencies are kept in sync
with each other.



Once this is working I (we) can work on extending these features.
