S3 Update


Paul Jones
 

S3 News from the factory, I've been authorized to leak this to you,

 

Production should start very soon, the delay is also because there is an optional board that is being worked on that is not complete yet, that will offer 50Mhz to 2GHz Frequency range, you heard it here first.... No price on the optional board yet...so S3 10kHz-2GHz at max of 24Mhz Bandwidth...

 

Have a Radiolutionary Day!

Thanks Paul... so what is the coverage without the board? is it just HF only?

Thanks Paul.

Might be too late for the bulk of this summer season though I guess.

Nice perspective Paul.  Is the optional board needed for the 24 MHz Bandwidth or has this only to do with the freq range ?

73,

Guido.


Paul Jones
 

Just the Frequency Range, has same Bandwidth settings as the S2/Duo/Duor with the addition of 12Mhz and 24Mhz

The S2 has coverage of the FM broadcast band by undersampling IIRC, I know of a few FM-DXers that use it that say it requires a pre-amp to achieve maximum sensitivity because without it it's a bit deaf at Band II frequencies. Is the S3 using the same method for VHF coverage, I don't have an issue with fitting a pre-amp but am curious about the design of the receiver.

What is the interface for the S3, USB or ethernet? The latter is notoriously noisy at low VHF frequencies so a well chosen fully screened ethernet cable will be required if it uses ethernet, hopefully something of quality has been selected by Elad should it ship with one.

Looking forward to the release, and the possibility of seeing all of FM broadcast in 16 bit!

Paul

Paul;

 

The S3 has a hardware pre-amp (so Franco tells me) built into the software (FDM-SW2). In quiet locations it definitely is needed. In high RF areas it is not needed. And yes, I agree both the S2 and S3 do very well with a big outdoor antenna but in some cases can be a bit weak without a pre-amp. So the S3 pre-amp is very welcome! In the screen shot below notice there is also a 10, 20, 30dB attenuator for the opposite problem (upper right corner marked ATT 0dB in the drop down menu). I have been lucky to alpha test an S3 and I can tell you that it performs very well for weak Meteor Scatter, weak Tropo and all kinds of Eskip and local conditions. I haven’t done any extensive A/B testing against S2 or an analog tuner but I’d agree that both the S2 and S3 seem just a small bit less sensitive than my best analog FM tuners (Yamaha T85 and a Denon TU800). Given that you can capture 24MHz at a time I am more than ok with this and actually no longer own an analog FM tuner, sold one of my S2’s and the other S2 has been loaned to a friend.

 

On your other question about the interface. USB3.1 (works on 3.0 ports, has the wider two level USB end). No Ethernet. Other things you may want to know are that it requires a 12VDC regulated power supply. This was a little disappointing to me as much of my FM captures are done in the car or on top of a mountain and S2 was perfect being USB powered. I have adapted and found there are some laptop battery replacement bricks that work well as a remote power supply for S3. Even a bunch of D batteries correctly wired works fine and make it through the airport without scrutiny.

 

My FM DX hobby has been completely transformed by the S3 (works great on MW too). In the past I had to run 4 serial captures with S2. With S3 Eskip across the full 20MHz is amazing! Meteor Scatter is just amazing to watch when it hits – sometimes you see the whole band light up, sometimes only select frequencies. The only downside is the hours and hours and hours that I have spent DXing from captures when I should have been doing something more family friendly….

 

One thing everyone should know about recording at 12MHz or 24MHz – you MUST have an SSD drive to record to. At 6MHz FDM-SW2 writes at about 50MB/sec. at 12MHz it’s 100MB/sec. That can usually be handled by most big 4, 8, 10TB “SATA” drives you can find most anywhere for under $200. However at 24MHz you need at least 200MB/sec and SSD is the only option for that (most SSD go to 500MB/sec). The first 2TB SSD I bought was over $500 a year ago. They are now under $300 although I’ve had mixed results with Micron SSD’s (skipping, what else?) and prefer this Sandisk which is now $240 and both of mine have been reliable. Disk space is also a concern – 8GB per minute at 24MHz!

 

And finally, if anyone is interested I can upload some S3 captures. I have some amazing Meteor Scatter I captured in super quiet Prince Edward Island and full dial Eskip from quiet North Dakota last summer. I could even upload a local dial capture and you will see why I never DX at home any more. As long as you have FDM-SW2 version 3.00 or later and an SSD drive you should be able to play these files. Just ask and I’ll upload sometime soon.

Hi Bill,

Would love to see a "local dial capture" since your home (Farmington) is almost my home (Wolcott).

Also, anyone know if the S3 will be for sale at Hamvention next week?

Sounds amazing, Bill! Thanks for sharing.
 
The requirement on storage speed and size will be a real issue with these beasts. I have been able to manage with three S2s on a fast desktop with a stack of 10TB SATA drives. The SSD requirement will lead to continuous copying of recordings. Is it really so that you cannot even play the big files back from a normal hard disk?
 
A great innovation would be a way to set the bandwidth of a recording on the fly. Especially with Es, the MUF varies quite rapidly and a continuous recording at 24MHz will create a lot of waste.
 
It would be nice to see and hear some of your captures!

However at 24MHz you need at least 200MB/sec and SSD is the only option for that (most SSD go to 500MB/sec). The first 2TB SSD I bought was over $500 a year ago. They are now under $300 although I’ve had mixed results with Micron SSD’s (skipping, what else?) and prefer this Sandisk which is now $240 and both of mine have been reliable. Disk space is also a concern – 8GB per minute at 24MHz!

 

And finally, if anyone is interested I can upload some S3 captures. I have some amazing Meteor Scatter I captured in super quiet Prince Edward Island and full dial Eskip from quiet North Dakota last summer. I could even upload a local dial capture and you will see why I never DX at home any more. As long as you have FDM-SW2 version 3.00 or later and an SSD drive you should be able to play these files. Just ask and I’ll upload sometime soon.

The S2 has coverage of the FM broadcast band by undersampling IIRC, I know of a few FM-DXers that use it that say it requires a pre-amp to achieve maximum sensitivity because without it it's a bit deaf at Band II frequencies. Is the S3 using the same method for VHF coverage, I don't have an issue with fitting a pre-amp but am curious about the design of the receiver.

What is the interface for the S3, USB or ethernet? The latter is notoriously noisy at low VHF frequencies so a well chosen fully screened ethernet cable will be required if it uses ethernet, hopefully something of quality has been selected by Elad should it ship with one.

Looking forward to the release, and the possibility of seeing all of FM broadcast in 16 bit!

Thanks Bill. You may not remember me, but you gave me some excellent advice several years ago on FM dx and it has helped me a lot. I am almost finished with an attic FM dx setup.  Health issues keep me from going on dxpeditions.

The comments regarding your test of the S3 is great stuff. Thanks for a glimpse into  the FM dx future. I have many questions about software though. Will FDM-SW2 be the dx software that you will; use??? (sorry to put you on the spot with that question)

Paul;

 

The S3 has a hardware pre-amp (so Franco tells me) built into the software (FDM-SW2). In quiet locations it definitely is needed. In high RF areas it is not needed. And yes, I agree both the S2 and S3 do very well with a big outdoor antenna but in some cases can be a bit weak without a pre-amp. So the S3 pre-amp is very welcome! In the screen shot below notice there is also a 10, 20, 30dB attenuator for the opposite problem (upper right corner marked ATT 0dB in the drop down menu). I have been lucky to alpha test an S3 and I can tell you that it performs very well for weak Meteor Scatter, weak Tropo and all kinds of Eskip and local conditions. I haven’t done any extensive A/B testing against S2 or an analog tuner but I’d agree that both the S2 and S3 seem just a small bit less sensitive than my best analog FM tuners (Yamaha T85 and a Denon TU800). Given that you can capture 24MHz at a time I am more than ok with this and actually no longer own an analog FM tuner, sold one of my S2’s and the other S2 has been loaned to a friend.

 

On your other question about the interface. USB3.1 (works on 3.0 ports, has the wider two level USB end). No Ethernet. Other things you may want to know are that it requires a 12VDC regulated power supply. This was a little disappointing to me as much of my FM captures are done in the car or on top of a mountain and S2 was perfect being USB powered. I have adapted and found there are some laptop battery replacement bricks that work well as a remote power supply for S3. Even a bunch of D batteries correctly wired works fine and make it through the airport without scrutiny.

 

My FM DX hobby has been completely transformed by the S3 (works great on MW too). In the past I had to run 4 serial captures with S2. With S3 Eskip across the full 20MHz is amazing! Meteor Scatter is just amazing to watch when it hits – sometimes you see the whole band light up, sometimes only select frequencies. The only downside is the hours and hours and hours that I have spent DXing from captures when I should have been doing something more family friendly….

Barry, I do remember you and am glad to hear my advice was worth taking! FDM-SW2 version 3.000 and higher works with S3. Happy to answer any questions about the S3 that I can. I will admit 99% of my use has been for FM DX 88-108MHz and a little MW. So go easy on me. And no, I know nothing about release schedules and product plans. The 2GHz board that Paul revealed the other day was a surprise to me!

Otso,

 

Yes, storage media is a challenge. I have 3 – 2TB SSD’s primarily so that I can fill one (about 3:45 at 24MHz), pull it off the laptop and put it on a second laptop and copy to a 10TB drive while I record onto a second 2TB SSD. I wish bigger SSD’s were available to the consumer market (at work I sell 30TB SSD’s ;-)

 

Recording is much more finicky than playback. Below shows my I drive – reading at 150MB/s and writing (recording) at 227MB/s. The numbers jump around a lot but expect peaks well above 200MB/s for recording. For playing back some big SATA drives might work ok. I like to use ATTO Disk Benchmark (free) software to test my SSD’s - https://www.atto.com/disk-benchmark/  It is surprising how varied the results can be especially between older and newer SSD’s.

 

I will upload a few 1 minute 24MHz recordings. At 8GB each Dropbox take an hour or two per file.

The requirement on storage speed and size will be a real issue with these beasts. I have been able to manage with three S2s on a fast desktop with a stack of 10TB SATA drives. The SSD requirement will lead to continuous copying of recordings. Is it really so that you cannot even play the big files back from a normal hard disk?

 

A great innovation would be a way to set the bandwidth of a recording on the fly. Especially with Es, the MUF varies quite rapidly and a continuous recording at 24MHz will create a lot of waste.

 

It would be nice to see and hear some of your captures!

Bill, thank you for the detailed reply about the S3, it's very much appreciated, while I'm used to covering half the band with another brand of SDR it doesn't have the 16 bit performance of the Elad. I won't be in a postion to use an S3 for this years Es season but hopefully we'll be up and running by 2020.

Otso,

 

My laptop is a 4 year old Lenovo W540. It works almost flawlessly for recording and playback (are any SDR recordings 100% flawless ???). One thing I like about this model is that I can remove the DVD drive and insert a caddy that can hold the 2TB SSD internal to the laptop. The caddy comes out in seconds to swap the SSD as well. The W540 also has a removable external battery (I have 5 of them). This design makes it very flexible for remote recordings. Newer laptops will utilize one or more internal NVMe M.2 style flash drives and some laptops are still available with swappable batteries (Lenovo P series for example). Of course not everyone will need the battery feature and some laptops draw less power and can be used with laptop battery “bricks”.  Do also remember that the S3 requires a regulated 12VDC power supply which at home is simple but on the road is a bit more effort.

 

The W540 specs are here - https://www.lenovo.com/us/en/laptops/thinkpad/w-series/w540/

 

I don’t know if there are specs for the S3 but any decent i7 and maybe i5 should do. For 12MHz (100MB/sec write) and 24MHz (200MB/sec write) captures an SSD is required.

Otso,

 

Yes, storage media is a challenge. I have 3 – 2TB SSD’s primarily so that I can fill one (about 3:45 at 24MHz), pull it off the laptop and put it on a second laptop and copy to a 10TB drive while I record onto a second 2TB SSD. I wish bigger SSD’s were available to the consumer market (at work I sell 30TB SSD’s ;-)

 

Recording is much more finicky than playback. Below shows my I drive – reading at 150MB/s and writing (recording) at 227MB/s. The numbers jump around a lot but expect peaks well above 200MB/s for recording. For playing back some big SATA drives might work ok. I like to use ATTO Disk Benchmark (free) software to test my SSD’s - https://www.atto.com/disk-benchmark/  It is surprising how varied the results can be especially between older and newer SSD’s.

 

I will upload a few 1 minute 24MHz recordings. At 8GB each Dropbox take an hour or two per file.

Sounds amazing, Bill! Thanks for sharing.

 

The requirement on storage speed and size will be a real issue with these beasts. I have been able to manage with three S2s on a fast desktop with a stack of 10TB SATA drives. The SSD requirement will lead to continuous copying of recordings. Is it really so that you cannot even play the big files back from a normal hard disk?

 

A great innovation would be a way to set the bandwidth of a recording on the fly. Especially with Es, the MUF varies quite rapidly and a continuous recording at 24MHz will create a lot of waste.

 

It would be nice to see and hear some of your captures!

 

BR, Otso

Wow the embedded screen shot looks terrible. Here’s a link to download it - https://www.dropbox.com/s/d74xmaoldx6sciu/S3.JPG?dl=0

Paul;

 

The S3 has a hardware pre-amp (so Franco tells me) built into the software (FDM-SW2). In quiet locations it definitely is needed. In high RF areas it is not needed. And yes, I agree both the S2 and S3 do very well with a big outdoor antenna but in some cases can be a bit weak without a pre-amp. So the S3 pre-amp is very welcome! In the screen shot below notice there is also a 10, 20, 30dB attenuator for the opposite problem (upper right corner marked ATT 0dB in the drop down menu). I have been lucky to alpha test an S3 and I can tell you that it performs very well for weak Meteor Scatter, weak Tropo and all kinds of Eskip and local conditions. I haven’t done any extensive A/B testing against S2 or an analog tuner but I’d agree that both the S2 and S3 seem just a small bit less sensitive than my best analog FM tuners (Yamaha T85 and a Denon TU800). Given that you can capture 24MHz at a time I am more than ok with this and actually no longer own an analog FM tuner, sold one of my S2’s and the other S2 has been loaned to a friend.

 

On your other question about the interface. USB3.1 (works on 3.0 ports, has the wider two level USB end). No Ethernet. Other things you may want to know are that it requires a 12VDC regulated power supply. This was a little disappointing to me as much of my FM captures are done in the car or on top of a mountain and S2 was perfect being USB powered. I have adapted and found there are some laptop battery replacement bricks that work well as a remote power supply for S3. Even a bunch of D batteries correctly wired works fine and make it through the airport without scrutiny.

 

My FM DX hobby has been completely transformed by the S3 (works great on MW too). In the past I had to run 4 serial captures with S2. With S3 Eskip across the full 20MHz is amazing! Meteor Scatter is just amazing to watch when it hits – sometimes you see the whole band light up, sometimes only select frequencies. The only downside is the hours and hours and hours that I have spent DXing from captures when I should have been doing something more family friendly….

 

One thing everyone should know about recording at 12MHz or 24MHz – you MUST have an SSD drive to record to. At 6MHz FDM-SW2 writes at about 50MB/sec. at 12MHz it’s 100MB/sec. That can usually be handled by most big 4, 8, 10TB “SATA” drives you can find most anywhere for under $200. However at 24MHz you need at least 200MB/sec and SSD is the only option for that (most SSD go to 500MB/sec). The first 2TB SSD I bought was over $500 a year ago. They are now under $300 although I’ve had mixed results with Micron SSD’s (skipping, what else?) and prefer this Sandisk which is now $240 and both of mine have been reliable. Disk space is also a concern – 8GB per minute at 24MHz!

 

And finally, if anyone is interested I can upload some S3 captures. I have some amazing Meteor Scatter I captured in super quiet Prince Edward Island and full dial Eskip from quiet North Dakota last summer. I could even upload a local dial capture and you will see why I never DX at home any more. As long as you have FDM-SW2 version 3.00 or later and an SSD drive you should be able to play these files. Just ask and I’ll upload sometime soon.

The S2 has coverage of the FM broadcast band by undersampling IIRC, I know of a few FM-DXers that use it that say it requires a pre-amp to achieve maximum sensitivity because without it it's a bit deaf at Band II frequencies. Is the S3 using the same method for VHF coverage, I don't have an issue with fitting a pre-amp but am curious about the design of the receiver.

What is the interface for the S3, USB or ethernet? The latter is notoriously noisy at low VHF frequencies so a well chosen fully screened ethernet cable will be required if it uses ethernet, hopefully something of quality has been selected by Elad should it ship with one.

Looking forward to the release, and the possibility of seeing all of FM broadcast in 16 bit!
