I must have missed it - When did someone from Radenso indicate Theia can transmit?

I looked for the post and I misread it... It would need a radar front end... it’s when we were talking about jammers.
Post automatically merged:

Any SDR with a radar front end has the potential to jam radar if someone writes software for it to do so, just like any computer can be used to run a botnet or for other illegal purposes. A SDR is just a computer hooked up to a receiver. Obviously we will not touch that with a 10 foot pole from a corporate standpoint.
Post automatically merged:

SDR’s can transmit signals though... but just the same with a regular detector.

but think about that... could you do that with a regular radar detector?

A receiver is a receiver is a receiver. Once you pick from one of several basic concepts (TRF, superhet, direct conversion, etc) you optimize the front end for the bands of interest and you optimize the displays / detectors / data presentation system for the signals of interest. A communications receiver and a radar receiver typically have the same basic blocks in them, with tailored capabilities. Remember that for later.
This is correct.

For the majority of the recent radar detector life cycle a superhetrodyne receiver appears to have been the norm. The RF is converted to IF and some kind of detection of the desired signals are done at the IF level. 20 years ago that detection was done with dedicated hardware circuits. In recent years some kind of DSP may have been applied to the IF or possibly the detected video. It could be argued that since that time detectors have been using “SDR”, although much less capable than Theia appears to be. This description and progression also applies to almost all receivers, not just radar detectors. For quite a while now, DSPs of one type or another have been replacing traditional hardware detectors or discriminators at the IF or AF level.
I see what you are saying, but that's not really how the term SDR seems to be used. If we relax the definition of SDR to anything that used DSP, ever, then pretty much everything that ever did a FFT could be considered a SDR. Obviously that's not the case.

The way SDR seems to be defined nowadays has to do with flexibility and modularity. The way that an Escort Max 360C is designed, you couldn't just put different firmware on it and have it demodulate wifi. There are numerous reasons for this, but just a few:

1. Antenna isn't suitable
2. Analog filter passbands aren't suitable
3. Tuning of the front end isn't designed for wifi since it has multiple mixing stages designed specifically for radar
4. etc, etc, etc

In comparison, Theia is a true SDR because you actually can do that just be switching antennas. By leveraging the power of DSP, we don't have as many hard analog filters that limit applications on the digitizer side. We don't have multiple mixing stages that limits frequency - besides the LMX2592 synthesizer built into the RF front end, we actually have a separate monolithic RFIC built into the digitizer that is a fully functioning and accessible I/Q tuner and demodulator. You could literally throw a DVB-S antenna on it and directly sample it!

I think it is important to keep in mind that we built the Theia digitizer to be multi-function from day one. Including a separate IPEX input where you can inject a signal, and other injection points where you can bypass the main radar-specific filter if you desire.

On top of the hardware flexibility, we have built Theia to be a Universal Software Radio Peripheral. What this means is that it is fully compatible with National Instruments and Ettus Research's IP. We actually have gnuradio running inside the FPGA on it, which means that it is indeed a fully standalone radio that can run any DSP block built for Gnuradio. This likely won't mean much to all but the most hardcore RF guys here, but I cannot overstate how powerful this is. We have actually had a couple of prime defense contractors reach out to us specifically because of this.

SDR comes in many flavors. Of them there are two common forms, you can have direct digital conversion (DDC), the ADC samples the RF directly and there are no traditional receiver sections, or you can have hybrid, a combination of traditional receiver techniques combined with SDR techniques. DDC tends to be the more expensive route, while hybrid brings good performance at more modest price points.
Theia can do either, depending on the signal you're looking to sample and what front end you have attached.

Remember what I said before? “A communications receiver and a radar receiver typically have the same basic blocks in them, with tailored capabilities.” In the past those tailored capabilities took the form of dedicated hardware circuits in the final stages, the IF or after. Today those tailored capabilities are in the software of the digitizer / processor instead of unchanging hardware. Outside the software receivers can start to look very similar, in fact they can be identical and you can change the function by changing the software.

Greatly simplified, I would not say they are “designing a communications radio and lobbing detector features on it”, as much as I might say they are designing a fairly standard modern receiver architecture, not done this way before in this specific market segment, optimized for the bands of interest (as all receiver designs are). And then they are applying some very unique signal identification techniques to the otherwise unremarkably processed signal.

Or, not trying to minimize the efforts here, just breaking it down into basic chunks, they are shifting radar detector hardware into the 21st century, using apparently high end but not particularly unique (outside the detector world) hardware, and then getting nicely creative with how the resulting signals are manipulated and identified.

T!
I very much agree with what you are saying about how the receiver design isn't novel. It's just novel in this industry. What we are doing has been done in the defense and communications world for a decade plus now from a receiver design standpoint. This is why I laugh when people attack me for saying that current radar detectors are archaic from a design standpoint.

I beg to differ since Theia can transmit as well and from the sounds of it transmit where and when it wants to. Not to mention take a signal and analyze it by looking at quadrature.
I see nothing in the so far demonstrated / imaged / videoed hardware that would allow Theia to transmit. Look at the digitizer board, it has an ADC, meaning it can sample, but cannot generate signals in any significant or adaptable way.


Almost any SDR based receiver, and that means most newer receiver designs outside the radar detector market (what I meant by “shifting radar detector hardware into the 21st century”), could look at the I/Q. Look at what I said in my post, this is what I meant by “getting nicely creative about how the resulting signals are manipulated and identified”.

Current detectors cannot pickup signals beyond radar bands. Theia can... and can be purposed for other things... I cannot use a V1G2 for anything else other than a detector.


Theia can also ingest or view all of the spectrum it is programmed to all at once and no other detector can do that as well.
Current detectors are limited by their front ends to police radar bands or small segments outside those bands. Theia will be similarly limited by its front end (antennas, band pass filters, LNA's, local oscillators, etc). Theia might have a bit more instantaneous bandwidth (that number is not out yet) but the front end will decide the tuning range. Unless the LO’s can be tuned across a wide range (and I have not heard that indicated yet) Theia will be similarly limited to the recognized radar bands or a bit more. And even if the LO's support wider operation the antenna probably will not. Designing a detector with a front end that works DC to daylight would be prohibitively expensive, and probably impact the detectors primary tasking, receiving and detecting police radars.

Can Theia be repurposed for other things? That has been discussed, but probably NOT without both hardware and software changes. If you think Theia, out of the box, can be repurposed to receive / detect police radio, for example, I expect you are going to be disappointed. I am quite sure the SDR and processor could be used for other things, but the front end looks pretty specific, as it should be to bring an outstanding radar detector to market.

As for you not being able to use the V1G2 for anything but a detector, I don’t know, I have not looked at the V1G2 architecture. But you appeared to miss what I said. Many modern receiver designs use SDR techniques. Theia may be the first radar detector to implement it, particularly to this level, but the techniques used (other than the classification techniques) are not unique to Theia outside the detector world.

“Theia can also ingest or view all of the spectrum it is programmed to all at once and no other detector can do that as well” is kind of a blind statement. Theia will have some maximum instantaneous bandwidth, as yet that is not known. I think the digitizer it uses has a 500 MHz bandwidth at the 3 dB points. A simplistic view would say that may define Theia’s IBW, but I suspect the sample rate will play a greater part in that.

Could a future version of Theia be broader banded and detect / classify / use many different signals? If that is a goal then yes, I think the hardware could be expanded to that easily. But I think the initial Theia releases are going to be radar detector specific, and may have some limited potential ability to detect other signals to the extent the front ends limit their tuning. Since it is an SDR the TYPE of signal it can detect and respond to is not limited by the hardware delivered, only by the software, but the specific signals it can detect will be hardware limited.

You apparently think I am bad mouthing Theia, or minimizing it. And that is simply not the case. I am looking forward to seeing what it can really deliver and unless the initial reviews are junk (no reason to suspect that) I am sure I will be throwing my money at it. You said (of Radenso) “You’re more or less designing a communications receiver and lobbing detector features on it” and my comment was, no, they are designing a 21st century receiver as the core of a detector, for the first time that I am aware of. Everyone else is further behind the curve, sticking with updated older designs instead of embracing what other fields have flocked to over the last 15+ years. But more important than the receiver design is the processing they are doing, that is the real departure.

I am guessing you probably posted this before reading my reply, but you will see that Theia also has a separate receiver in the digitizer.

The LO built in the front end can be tuned from 20-9800mhz plus a multiplier, but the usefulness of this would be limited because it is located inside the antenna housing (so you're stuck with a radar-centric antenna).

That limitation doesn't apply to the I/Q receiver located inside the digitizer, which we use to sample the IF. Instead of sampling the IF, it could be used for broadcast television for example. It can also be used for pretty much anything in the 9xxmhz ISM band without any hardware changes.

If you wanted to use Theia for something else outside of that receivers tuning band (off the top of my head, about 2.3ghz) then you can just either pipe in a signal to the IPEX connector that has already been down-converted to an IF in between 925mhz and 2.3ghz or plug in a new front end to the samtech connector.

EDIT: I want to be clear that I am not saying Theia can be used for ANYTHING with zero changes - that's not true.

1. It can be used without hardware changes for radar
2. It can be used without hardware changes for anything between 925mhz and 2.3ghz (such as DVB-S, ISM band, etc). This only requires a new antenna to be plugged into the the IPEX connector.
3. It can be used for anything that can deliver an IF between 925mhz and 2.3ghz from a separate front end.

That is huge level of flexibility, especially because when I say "used for" you have all that plus a FPGA on a handheld device.

Yes, I did. As soon as I saw your response I understood a few things better.

The LO built in the front end can be tuned from 20-9800mhz plus a multiplier, but the usefulness of this would be limited because it is located inside the antenna housing (so you're stuck with a radar-centric antenna).

So out of the box your limitations are going to be the bandpass of the antenna. That makes sense.


Are you going to be able to access the LO / mixer combination in any kind of bypass configuration? I suspect not as that is probably part of the cavity / assembly of the antenna. I understand the optional connector that will bypass the front end, but what if I wanted to leverage your LO and front end behind the antenna?


What you are describing is more or less what I had in my mind from the videos and pictures, however without the specific freqs and limits. It sounds exceptionally flexible with a lot of potential. I suppose that as a company you will not explore very many of the potential configurations, but it might be very neat to see what develops outside the company in the way of “after market” or as hacks.

I see what you are saying, but that's not really how the term SDR seems to be used. If we relax the definition of SDR to anything that used DSP, ever, then pretty much everything that ever did a FFT could be considered a SDR. Obviously that's not the case.
Yeah, I don’t mean to say anything with DSP in the IF or AF is SDR, although that has been used that way in marketing in the past.

I corrected myself after I misread a post... but Theia as Jon has alluded to has much more functionality than you think.

Not really. I have a fair understanding of the potential of the platform in a general way. I understand what is possible using an SDR, I have used SDRs, professionally and as a hobby, for years. However, out of the box as delivered it will be a radar detector and little more, potentially a game changing detector, true, maybe THE detector, but still a detector. It will take hardware changes to be seriously much more than that, changing the input to the digitizer / SDR. The core electronics are capable of more, the processor and digitizer, but the front end optimizes it to a specific task with limited applications beyond that. Software changes, the adaptability of the system from the IF back, cannot change the limitations of the front end.

The core Theia hardware could be used to detect and receive police radio, if you change or eliminate the front end hardware. The core Theia hardware could be used to track ADSB from police aircraft and warn you of proximity, if you changed the front end hardware. Actually, that last one, the antenna / front end would significantly limit performance on ADSB, but I wonder if enough signal would still be usable to warn of close ADSB sources since those are all you would care about? That might be a question for Jon, have you guys, in playing around, tried to put something like a 1 GHz signal into the detector front end and seen what the losses were? From Jon's previous post the mixer and LO would be fine for the task, but the antenna is probably going to be extremely lossy, which may not matter much for detection of close sources.

Beyond it looking like it has the potential to be a great detector, there is potential for this to be a hackers dream. There is potential for Radenso to really expand on Theia beyond a radar detector, but I doubt there will be a large market for that effort.

By the way, I think what was being said in the post you read about transmitting is that some SDRs can transmit, however it looks to me like the hardware selected does not. And that makes sense, Radenso probably does not want to get caught up in any of those legal pitfalls, and transceive capable SDRs would increase cost, complexity, size, etc. No sense in including factors that will decrease your market share while increasing your corporate expose, coincidentally resulting in hardware that would be illegal to operate even if you could find some way to market it.

Yes and no.

I think some people might be taking my comments out of context. When you refer to "out of the box," you are correct if you take out of the box quite literally. The key to remember with almost any SDR is that it can only run one front end at a time. The included Theia front end will be a radar front end. You're not going to be detecting KA band plus broadcast TV at the same time. People aren't going to be buying Theia and using it to watch OTA TV without investing some effort.

But really, there are two "front ends" in Theia. The high frequency RF front end and the lower frequency front end built into the digitizer. 99.999% of people here on this forum will be using the RF front end and that's the end of it.

But, if you are a technical person and a RF hobbyist, you don't have to. You could unplug the RF front end from the samtec connector and simply plug a different antenna into the IPEX connector (after you enable it by jumping it on the Digitizer) and "out of the box" the hardware could receive ADS B, broadcast TV, etc. I say that with the caveat that we will not be supporting this from the software standpoint from day one (we are manpower limited and need to focus on radar), but the hardware could absolutely do that. And if you know what you're doing, the device would work "out of the box" with gnuradio to do so.

If folks want to play with SDRs, you can get basic ones for $20~$30, install some free software and away you go. In the old days (like 2013 or something) you could get RTL-SDRs for like $10, that's what brought SDR to the hobbyist masses. Theia is using significantly higher quality hardware, but the concepts are the same.

You corrected yourself only after you were asked to provide proof Radenso said Theia would transmit.

Jon has done much more than allude to Theia's functionality. Almost every post and video by Jon and, other members of the Radenso team, give examples of how Theia will work at general availability and what their architecture could support. Anyone who has watched/read them and commented indicate they are very well aware of Theia's potential.

And if you know what you're doing, the device would work "out of the box" with gnuradio to do so.
(My bold added.)

And that was all I was trying to say in that part of my discussion of the capability of Theia (which was a small part of what I originally said, but seems to have become a focus). Some people seem to be under the impression that if they load different software to Theia they can turn it into a police radio detector, or a ADSB detector, or whatever, plop it up on their dashboard in its original, as delivered, configuration and away they go. And that it will potentially be able to do both radar detector work and this other work, all at the same time, just because the software was changed.

I don't deny that it has the potential to receive all those things, an SDR doesn't care what the RF is doing, as long as the signal is in its band or can be shifted into its band you can do what you want with it. And by including that other input you guys have made it potentially very easy to do and the system should be a lot of fun to play with. But, it is not going to do most of those things as delivered without some work, it will not just be a software change or a firmware push that allows that operation. That was what I was trying to dispel. Except I still wonder what the efficiency of the device would be, as delivered, if you tried to tune ADSB. Sure, I know, way down in gain (and no longer have the same directional properties), but might it be sensitive enough to detect near ADSB sources?

I look forward to the product, both as a detector and I really want to see what happens in the "lets play with it" space. I have a couple ideas, and you introduced me to DS Instruments. We were building, in house, a compact downconverter for a test rig, and ended up going with a DS product as easier and lower cost after one of your videos.

And that was all I was trying to say in that part of my discussion of the capability of Theia (which was a small part of what I originally said, but seems to have become a focus). Some people seem to be under the impression that if they load different software to Theia they can turn it into a police radio detector, or a ADSB detector, or whatever, plop it up on their dashboard in its original, as delivered, configuration and away they go. And that it will potentially be able to do both radar detector work and this other work, all at the same time, just because the software was changed.

I don't deny that it has the potential to receive all those things, an SDR doesn't care what the RF is doing, as long as the signal is in its band or can be shifted into its band you can do what you want with it. And by including that other input you guys have made it potentially very easy to do and the system should be a lot of fun to play with. But, it is not going to do most of those things as delivered without some work, it will not just be a software change or a firmware push that allows that operation. That was what I was trying to dispel. Except I still wonder what the efficiency of the device would be, as delivered, if you tried to tune ADSB. Sure, I know, way down in gain (and no longer have the same directional properties), but might it be sensitive enough to detect near ADSB sources?

I look forward to the product, both as a detector and I really want to see what happens in the "lets play with it" space. I have a couple ideas, and you introduced me to DS Instruments. We were building, in house, a compact downconverter for a test rig, and ended up going with a DS product as easier and lower cost after one of your videos.

T!
DS Instruments makes AMAZING stuff. I can honestly say that we would be totally screwed in development without their stuff, and that if I found him earlier it would have saved me $10k+ trying to build our own downconverters. I can't believe how intuitive to use his products are as well.

As for the ADS-B, that also depends. When we ran the prototype front end with some SPI control wires that went outside of the shielding I know we could detect ISM band signals loud and clear through the wires. When everything is internally shielded inside the enclosure that doesn't happen as much.

You corrected yourself only after you were asked to provide proof Radenso said Theia would transmit.


Jon has done much more than allude to Theia's functionality. Almost every post and video by Jon and, other members of the Radenso team, give examples of how Theia will work at general availability and what their architecture could support. Anyone who has watched/read them and commented indicate they are very well aware of Theia's potential.
Oh excuse me for mis-reading and or remembering a post made weeks ago wrongly and correcting it/admitting I’m wrong. I’m a human... are you?

All hail mighty MikePA who’s never made a mistake in his life... we should worship him.

Alright guys, come on.

@MikePA , there's no need to constantly and officiously defend Radenso in every thread. They can do that themselves when and IF it's ever needed.

@CobawLT2010 , I can see how Mikes post could get under your skin but there's no need for retaliation.

Let's all get back to the interesting SDR conversation that I've been enjoying myself.
