I use SDRC with the LimeSDR.

 

Re-visiting my calibration settings today I have a question. When I add a ppm correction to the main oscillator using a known received signal (in my case -0.25ppm) it appears only to affect the receiver. Transmit frequencies are then offset with respect to indicated frequency by an amount proportional to the frequency and the ppm. Is this correct, or have I missed a setting so that the correction applies to both?

Simon,
Thank you so much. Your attention to detail and response to users requests is extraordinary. SDR Console is a fantastic program because of your efforts. You set an example to all programmers for how it should be done. Very much appreciated. Time for everyone to hit the donate box. Cheers!

Hi,

 

Looking at the SDRplay support in SDR Console I see old code from the first version with 100ms buffering, the more recent SDRplay APIs (V3) have very, very low latency so I’ve just removed the need for this buffering.

 

This change will be in the next update to v3.1.

Totally unscientific measurement:

SDR-duo to SDR Console 3.1 to WSJY gave average DT of 800 ms

RX-888 to SDR-console to WSJT gave average DT of 300 ms.

Console 3.1 was showing audio of 55ms

Computer time from local university SNTP server and Dimention 4.

 

Both these are more than usual . Last time I looked it I saw less than 100ms for RX-888 path and 300 for SDR-Duo path. Of course one is from USB2 port  and one from USB3.

Sorry to hear of your woes. Condolences and I dare say things feel a good deal harder than you let on in your post. Hats off to you and hope things become a little easier as time goes on. Hopefully messing about with radios keeps the mind occupied. I've got huge sympathy as my other half has long term disability (20 years+) so I've got some idea of the difficulties it all presents on a daily basis. Easy jobs become huge jobs. Radio is a good mental distracter from daily difficulties. Even if for short periods it's a break.

As Simon says, there's been a huge surge in vegetarian and particularly vegan foods in the supermarket in the last couple of years. They finally realised there is money to be made and that's when it all kicked in, thanks no doubt to the much larger number of veggies and vegans in the younger generations. Unfortunately (as with all packaged foods) one has to keep an eye on ingredients. Vegan or veggie sadly does not necessarily always mean healthy. For example, many veggies resort to eating large numbers of meals with cheese to get flavour and that's not necessarily a great thing for fat intake!

There are plenty of meat substitutes out there. One brand you might try is "Like Meat". Some of their breaded chicken style items are very hard to tell from the real thing. Processed of course but not bad ingredients. Tescos do their on range of vegan foods and specifically a range called "Wicked" which have quite a few nice and tasty lines. One of the hardest things I found to give up was milk, and switching to soya milk. There are some great soya milks and some awful ones. Alpro are one of the better ones. I much prefer the unsweetened varieties. What I found is that having made the switch, if I now ever taste cow's milk in tea or on cereal it tastes incredibly (and unpleasantly) sweet. Basically I find in life one can often find the change the difficult part, but persevere and the body gets used to the new way in a couple of weeks and it becomes the new "normal" for you. Many people give up after a day or so without giving it a real chance.

Anyway, good luck with it, and there's always "flexitarian" where you just cut down on the meat and maybe have it twice a week and veggie/vegan for the rest of the time. Can be a good transition option on the way to full veg!

Re: Latency with RSPduo #rspduo

I'm feeling picky today.

That's MHz ( Mega Hertz) not mHz (milli Hertz ).

Then note that sound is a indeed remarkably light load on a computer. A 16x16 audio matrix with a simple equalizer and adjustable levels and delays on each channel and each matrix cross point is well within a rather old single core processor. The system I am thinking of uses one AudioScience audio card and an Advantech GPIO card for control. It used ASIO audio. It has a 7ms latency end to end WITH all that processing.

If you think about it you MUST be able to perform all the audio processing for a buffer of samples within the time period between received buffers. Otherwise you start running behind. Multiple cores can buy you something if processing can be broken up into independent enough chunks that they can work in parallel. But all the processing still must take only the time between samples. You can buy a little by using larger buffers. Buffer size (64 samples in the case cited) is what sets your latency, The same issue exists with SDRs. And some SDRs use large buffers chiefly in support of the filtering techniques used. When a filter is manufactured by running the signal through an FFT, filtering the results setting frequencies outside the filter's passband to zero, and then using a second FFT to convert back to the time domain you see this trade off directly. If you want to generate a 100 Hz filter you need to collect on the order of 10 ms to 20 ms of data before you can run the FFT. Overlapped FFT is used to reduce that latency a bit. But that latency then becomes a minimum that is supported, Then if you are feeding audio buffers that are large you have that large time delay added to the SDR processing.

In theory SDRs should have the same real delays that analog radios have. Usually it is somewhat longer to several times longer depending on the priority the author places on end to end latency.

Now, if we are talking AirSpy (R2) and not an AirSpy HF+ (Discovery) model then, yes, you require a boatload more CPU. You also will very probably require a dedicated USB bus. An AirSpy at 10 Msps loads the USB bus to between about 3/4 capacity to full capacity. I solve THAT issue with one of the good PCIe plugin USB cards. I have a lot of "stuff" here so the computer currently features a pair of such cards with four USB ports and four USB controller chips onboard. That works a treat. You can tell if something like that is needed by running the AirSpy at one of its lower rates, which are lower bus loads. If there are no skips for that and there are at its full 10 Msps rate and its "packed" transfers option turned on then the separate bus card is needed.

This USB issue does not affect latency, however. It simply addresses data dropouts, clicks. Very often the USB bus CAN impose a practical minimum latency on your project. It works best for these applications for large bulk transfers. Large bulk transfers take time. So there is a trade off in there which is difficult to avoid. If ultra low latency is required you MAY have to find an SDR front end that is a PCIe card or uses Ethernet for transfers. The former is best. Ethernet still has "optimum size" transfer and bus congestion issues.

Your points regarding "turning off all the extraneous junk" is sound. You can sometimes (very often in my experience) gain performance on a given CPU by using task manager to increase priority to above normal or highest. Realtime makes a further improvement but must be used carefully after much testing. With 10 you also cannot get to realtime without administrator privileges, which is an annoying but good thing. (It took some serious clever thinking to get around this limitation for some theme park ride vehicle installations. The nature of the use actually made a clever work around practical.)

Steve, I think you diagnosed your own problem.
the pan adapter that works is “only” 192KHz bandwidth.
the sdr is up to 10mHz bandwidth!
2 channels (I/Q) or 192KHz is nothing to a modern cpu, it’s pro audio bandwidth stuff and with only 2 channels won’t need much processing, so, low latency. I fact it’s probably using fairly standard audio drivers to deliver the data to the pan adapter code.

but…
you start using an wide bandwidth SDR, it’s going to get real hungry, real fast. 10MHz display/decode bandwidth needs a big chunk of USB bandwidth to deliver it and a big chink of cpu power to make it meaningful, then you have to display it as it’s constantly changing depending on your spectrum/waterfall refresh rates and resolution and… you either drop samples somewhere or you have latency.

This is a common and much discussed issue in digital pro audio circles. Latency between the performers own voice and what they hear is devastating to the performance. Of the sound engineer adds more processing such as equalizers, compressors, etc. to the signal chain there’s more latency.  It wasn’t an issue before digital sound but there was still the delay due to the speed of sound and distance from the pa speakers (about 1ms per foot as a rough guide).

Purpose built software such as spectrum analyzers con concentrate on lower latency but general purpose signal processing software such as an SDR has the goal of ending up with recognizable and copyable signals and hence uses much more processing to achieve that goal, so, low latency isn’t a primary design goal, DSP is.

“Better sdr devoce” is a vague statement. If the device is moving a few MBytes/second of data through a USB port, your going to have latency right there. If the SDR software is any good, there’s more latency. I really doubt that your going to find a reasonable solution at any kind of reasonable cost. It’s just how they work.
Can you not use the built in nulling abilities of the Duo with SDRPlay to do the same thing as the touchy antenna phasing unit? 
The duo is phase coherent for both of its receivers so latency isn’t a factor between them. It’s not just two rap’s in the same box.

You could try throwing a much more powerful computer at the problem. Again, in the pro audio industry they are often purpose built desktop computers specifically put together for high speed computing with bags of memory, multiple very fast cpu’s, solid state disks, and high speed graphics cards with their own large amounts of memory.
All extra garbage is removed or shut down. Add on “virus and internet protection” is removed (the built in one from Microsoft for windows is just fine btw, the rest are just taking money from you and pretending to do something different). All background auto updates are stopped, basically anything that takes a cpu cycle and is t needed for the real job is destroyed with extreme prejudice.

I hate to suggest it on this forum, but, if you have an Nvidia graphics card that qualifies, give SDR-Console a try. It uses the graphics processing chip to offload much of the DSP from the main cpu and is extremely efficient when using the GPU in this manner.

it’s not, specifically, the hardware part of the  radio that’s “at fault” here. It’s a combination of things that have ganged up on you in your specific use. No single “fix” is going to be particularly effective, you have to look at the system as a whole, identify what’s the largest cause of latency and deal,with that. Then move on to the next largest  cause and so on. You also may have to accept that, after spending countless hours and loads of money, it will never be any good as there just too many factors, or there’s a factor that simply cannot be overcome without use specific coding that gives up something else that’s needed.

Re: frustrating

Tom Crosbie G6PZZ
 

Simon,

Unfortunately walking is not really an option for me. I had a massive stroke 14 years ago which has left me weak on the left side. I’d got to the point of walking with a stick and mobilising around the house etc. but after 10m or so I get exhausted. More recently my mobility has suffered and needed extra help to walk that far as I kept falling. Three months ago I had a nasty fall and couldn’t bear weight on the weak knee and was in a rehab centre for a month, followed by two months in a care home getting used to my new walking frame. My wife had been my full-time carer during those years but as the first lockdown kicked in, she was diagnosed with a rare and incurable cancer and she passed away last month.

 

When I get back to the gym at my stroke centre my mobility will improve again to the point where I can get back to using a stick again, sadly not one a dog would fetch! Does Millie also eat a vegan diet? Finally sent some dog food late last night.

Simon, Max and Simon,

 

You’ve almost convinced me to go veggie. Certainly in my current condition I could simplify my eating habits as I need to loose at least a stone to get my BMI down from borderline obese to just overweight. After all, I’m not going to grow six inches!

I’m not convinced that eating only meat and putting my body into ketosis to burn fat is a good option either. Did I mention that I am type two diabetic? Loosing weight could cure me of that, or reduce my dependency on medication.

 

Right. I’m going for it. I think I can become 80% veggie for the first month, starting today. I certainly don’t have the willpower for vegan but who knows what the future will bring. Salad for lunch today and steamed broccoli and cauliflower for dinner…

I’ve always been a minimal meat eater, nowadays it’s very easy to eat a vegan diet. Many, many farming / food start-ups are vegan and the quality is improving all the time. It’s the way of eating which has the lowest footprint, also arguably the healthiest.

I don't "bang on" about it because there is no point in trying to explain it to those who will never even make an attempt to understand another person's (or any living creature's) viewpoint, which is called empathy by the way. If invited to explain, it's my empathy for the animal that makes me vegan. And yes, I do understand that's not the reason all vegans choose that diet.

End of "banging on"!

Tom,

 

Go online to ASDA / Sainsbury’s / Tesco and look at what’s available by simply typing vegan into the search. You’ll be amazed.

 

A great way to lose weight is to get a dog and go walking.

Simon, Max and Simon,

 

You’ve almost convinced me to go veggie. Certainly in my current condition I could simplify my eating habits as I need to loose at least a stone to get my BMI down from borderline obese to just overweight. After all, I’m not going to grow six inches!

I’m not convinced that eating only meat and putting my body into ketosis to burn fat is a good option either. Did I mention that I am type two diabetic? Loosing weight could cure me of that, or reduce my dependency on medication.

 

Right. I’m going for it. I think I can become 80% veggie for the first month, starting today. I certainly don’t have the willpower for vegan but who knows what the future will bring. Salad for lunch today and steamed broccoli and cauliflower for dinner…

Max,

 

I’ve always been a minimal meat eater, nowadays it’s very easy to eat a vegan diet. Many, many farming / food start-ups are vegan and the quality is improving all the time. It’s the way of eating which has the lowest footprint, also arguably the healthiest.

 

When I was a student in the 70’s it was mainly lentils; fried, stewed, yuck 😊 .
