The problem is not on the Si5351 XTAL, but on the Audio XTAL.
The Si5351 is perfectly trimmed with a PartsPerBillion parameter.
Mine is trimmed to set 900MHz on Synthesis Stage 1 output PLLA or PLLB.
This can be demonstrated by align a CLK output onto an existing signal like DCF77.
Of course, the multisynth parameters a,b,c and r_div must be as precise as possible.
The CLK output delivers a signal of 77500.000019709390Hz (a=1451, b=642674, c=1048574, r_div=8).
This is easy to check that CLK output is aligned onto DCF77.
Another step is to produce the IQ frequency, 4*(77500Hz+12kHz)=358kHz (a=1256, b=1030949, c=1048522, r_div=2).
The CLK ouput si 358000.000001516542Hz and after divide by 4 and substract 12kHz, f=77500.000000379310Hz.
Onto the SDR# display, the misalignment is about positive 0.1Hz as displayed at -12kHz. It is twice at -24kHz. It is negative at +12k or +24kHz.
This is an audio problem which needs another ajustable parameter in SDR#.
The misalignment is proportional to the delta frequency relative to the IQ frequency, 77500Hz+12kHz in this example.

After brainstorming, it's appear that this misalignment is the audio card sampling rate, about 10 ppm, probably the intern quartz or the PC quartz ?
My audio card is a Sound BlasterX G6.
The IQ Local oscillator is as printed: 12kHz of the desired frequency.
Searching in SDR# config file, I haven't found a parameter to set the audio ppm. Is it correct ?  

Another request: It could be appreciable if the negative frequency be printed in the top line, not only the positive frequency.

Best regards and many thanks for this beautiful software.

IQ from Sound Card - missing ppm @elektor_sdr_shield #arduino

Hi all,

Yes I agree with Guido. It would be a huge benefit to FM Band dxers to have this lock implemented. It has been very frustrating in the past to tune the band while dx has been coming in and accidently drag the span.

No problem. I understand what you are trying to achieve. I have the following complete already: frequency lock, audio gain lock, bandwidth lock, detector lock. i am working on getting the displayed bandwidth lock functioning properly. Once completed tonight or tomorrow, i will post a link where the beta can be downloaded.

Hello Ed,

 

Thanks for putting effort in this.

 

It is indeed a Span Lock like Joe called it I am looking for.  Most other SDR software do this automatically when in IQ recording mode.

 

In SDR# when recording you can still drag the span or click near the border which results in a shift.  When playing back the recording the frequency read out will not be correct anymore beyond the time you were dragging.

 

73 and thanks again.

 

Guido.

Guido I think I understand what you are looking for...

 

Tune the LO and and the marker is restricted to only move in the displayed bandwidth. Is this correct?

 

If so I could make you a plugin to do this very easily.

Hi Airspy.US team,

We are working to expand shipping, but we have to make certain that we do not open our website up for shipping other Airspy product outside those areas we are authorized to ship. On top of that, there is a higher-than-normal workload for a smaller-than-normal staff. This will be magnified many times when the next batches of YouLoop are received, as the current plan is to *not* bring in extra packers due to the current COVID matter. As of this moment, we are still shipping and we expect YouLoop inventory any day now. Shipping routes that have always taken two days over the past several years are currently estimated at a full week. The first two batches of YouLoop also took two days, so that is on par with the normal expedited shipping and may be similarly affected.
Currently, we have about two to three times the number of back-orders we have ever had. The upside to this is that the YouLoop will not need firmware updates, ESN registration, or calibration, so packing should proceed quicker than with previous back-order situations.
As for right now, we would recommend anyone in Europe, Asia, Africa, or Australia place your order with RTL-SDR, as they likely have had global shipping established for many years. We did not anticipate the new distribution setup for the YouLoop and certainly did not anticipate the changes COVID-19 made necessary. For customers in North or South America, or any USA addresses, our current system can handle those orders.

I can add my voice to the pleased new users of the YouLoop. Mine came in the mail yesterday (thanks for the quick shipping, AirSpy US!).

I initially was disappointed with what I thought was a faulty YouLoop antenna..I had tried multiple receivers including the HF+ Discovery and different lengths of coax lead-in, and wasn't getting ANY signals, even my local medium wave stations. One of them is as strong as -21 to -13 dBM, depending on which active loop antenna I'm using at the time; I figured at least this station should show up on the YouLoop.

Well, I had jumped to conclusions. After further investigations today I discovered a bad SMA Male to BNC Male adapter! My other two such adapters on hand proved to be just fine and the YouLoop came to life! I'm impressed with this AirSpy antenna considering its passive nature and reasonable cost. This will be a fun antenna to use while traveling and camping, as it is so compact and can be deployed quickly. You can even just drape it over a convenient shrub or branch and it will work well.

So, may my experience be a reminder to others--don't automatically point your finger at an antenna if at first it doesn't seem to work right (or at all). There are other links in the receiving chain, and in my case this small adapter was actually the bad link. The YouLoop itself is fine, and I know others who have bought this antenna will be pleased.

I can add my voice to the pleased new users of the YouLoop. Mine came in the mail yesterday (thanks for the quick shipping, AirSpy US!).

I initially was disappointed with what I thought was a faulty YouLoop antenna..I had tried multiple receivers including the HF+ Discovery and different lengths of coax lead-in, and wasn't getting ANY signals, even my local medium wave stations. One of them is as strong as -21 to -13 dBM, depending on which active loop antenna I'm using at the time; I figured at least this station should show up on the YouLoop.

Well, I had jumped to conclusions. After further investigations today I discovered a bad SMA Male to BNC Male adapter! My other two such adapters on hand proved to be just fine and the YouLoop came to life! I'm impressed with this AirSpy antenna considering its passive nature and reasonable cost. This will be a fun antenna to use while traveling and camping, as it is so compact and can be deployed quickly. You can even just drape it over a convenient shrub or branch and it will work well.

So, may my experience be a reminder to others--don't automatically point your finger at an antenna if at first it doesn't seem to work right (or at all). There are other links in the receiving chain, and in my case this small adapter was actually the bad link. The YouLoop itself is fine, and I know others who have bought this antenna will be pleased.

Hi folks,

I hope you're all keeping safe and healthy during this madness.
I've had no direct replies to the below email, reposting in case it was missed by any retailers.

Thank you to any retailer who is able to reply.

If any retailers on this list are able to send to Australia and require an expression of interest to be eligible to order please let me know and I'll contact you direct.
Looking forward to one of these antenna's, perfect for use in my little upstairs unit during the COVID19 lockdown!

Gary, (and note there is general info for everyone below the first paragraph)

You are very early on Batch 3. We will be reaching out to some in the first two batches (about a dozen) who "pre-ordered" (sent emails expressing interest) and have not yet placed an order. If those units are not ordered/claimed, we will fill pending orders in order and you may be early enough to receive one of those antennas. Aside from that dozen or so, batches 1 and 2 are sold out and shipped. Batch 3 is sold out and awaiting inventory replenishment.

We are currently working on Batch 4 and have about 52 units left in that batch. We will fulfill orders as inventory is received. As most everyone knows, international shipping is not running on a normal schedule currently. But we hope to receive batch 3 (and maybe batch 4) in the next week or two. We will likely order batch 5 very soon.

The run on the YouLoop has been perhaps the largest demand over all previous product releases.

To address a few recurring questions:
* We do not know when the preamplifier will be available.
* We do not know the price of the preamplifier.
* The loop diameter is approximately two feet.

Also please keep in mind the current climate of minimal staff available to process and pack orders. We are not calling in extra help at this time given the desire to keep everyone safe and minimize the chances of exposure to COVID-19 even though we are still in a modestly hit zone (only a few cases in our area with the closest about 10 miles or so away). On the other hand, it's not as if there are a lot of "regular off-hours activities" to take time away from packing orders. But I do not plan on the 20-hour days that we had with the Black Friday blitz either. Our current strategy is to limit contact to only incoming inventory (with a preference that items are left outside using visual approvals), and with the post office clerk when orders are shipped. We MAY limit shipping to three days each week (Monday, Wednesday, and Friday) to further reduce that contact. But if we have enough orders to justify shipping, we will ship that day even if it is on a Tuesday or Thursday.

We have been looking into UPS as an option for larger orders, but that is in a holding pattern currently.
We are also looking at other options as we all deal with this pandemic.

We expect to be shipping as long as USPS is available, as we have emails from more than one US Federal Government agency who have placed orders stating that they are in "urgent need" of the ordered products. Since there is no time difference to scan one package or one hundred (they are all scanned on a single consolidated shipping form), we see no impact of adding other orders to that delivery. We also fall into more than one category authorized to remain open under current Pennsylvania business closure mandates.

For Airspy SDR stock, we are still looking good for now with the exception of the HF+ Dual Port which is out of stock. We have a pending order of Airspy inventory that we expect soon, but again delivery time is uncertain. All accessories are also in good supply. When things started hitting the fan, we ordered extra stock in anticipation of uncertain availability. Our goal was to get to 200% of normal stock, and we got a good way there on the best sellers.

In case not everyone has heard, the Dayton Hamvention is cancelled this year so we will not be in attendance.

Stay safe everyone. This is a good time to enjoy using Airspy SDRs while we practice social distancing and avoid social activities.

Re: IF Spectrum Display ?

EB4APL
 

Hi Bob,

This is controlled by a plugin named Zoom FFT. It allows to use new displays with the IF Spectrum, Audio Spectrum and MPX Spectrum.

The IF Spectrum shows a zoom of the spectrum around the frequency that the radio us tuned to. It s possible to see the filter position and it is a good thing to change the filter width, just dragging its borders, so you don't need to zoom the main display to do it. It also allows to change the width asymmetrically.

The Audio Spectrum shows what its name implies in another display. You can control the width of the audio filter in the same way.

The MPX Spectrum is intended to monitor the full bandwidth of a broadcast FM stereo station, showing the audio,  stereo subcarrier and the data one if any. It only appears when the radio mode is WFM.

Every spectrum window can be switched on or off with the tick boxes on the Zoom FTT plugin. If you don't want any, you can remove the plugin in the "Plugins.xml" file, but I don't recommend it, it is better to have all IF displays off and turn them on when you want, because then to use the plugin you need to edit the plugins file and reload the program .

Regards,

Ignacio   EB4APL

Hello,

In SDR# I have the normal Spectrum Display, and the Waterfall showing.

I also have on the bottom, a small display called: IF Spectrum.

How is this utilized ?

And, how would i remove it:  can't seem to find the option that controls it, and don't recall ever
pulling it up (from somewhere) ?

Thanks,
Bob
