Hear that ELV, our Mr Caldeira may translate more of your manuals. So we hope you send more candytronics to him. As for me, I only ask for the KT-200 to be sent to me for a review 😂😂 Thank you Mr. Caldeira for being impartial and critical about the unit. We appreciate knowing your opinions prior purchase. You are a stand up person 👍
adafruit has a module for about twenty bucks that uses the Si4713 family of chips. The ELV is nicely packaged, the adafruit module requires some "getting your hands dirty" with arduino
Thanks for the video. Looks like a really cool bit of kit. I have the same concerns you mentioned plus one more. The output is labeled 75 Ω whereas most of what I would be using it on would be 50 Ω.
most of the “modern” receivers have a 75 ohm antenna, which is why this unit has that impedance. Most of what I do uses 300 ohm, so i’m going to have to use an L-pad to match.
That's a good bit of kit, I was looking for something to do the same thing myself. I ended up picking up a HP 8647A and refreshing the power supply on it. Works great but no stereo FM. I don't know how hard it would be to get this from Germany (to Canada) but I will look into it soon. Cheers,
@@electronicsoldandnew - There's a clown on ebay that will sell you a board for an DN Gen., but doesn't supply the parts or PIC, only the board! That just doesn't make since!!!!
Will be interesting to see what you use for impedance matching from 75 unbalanced to 300 balanced. Or 75 to 230. I built a device with minicircuits transformers. Works really well.
Looks like a nice kit, and easy to build for sure. My first thought was that it came with a bag of components and a empty PCB. Kind of odd that the signal comes out on a RCA connector and not a BNC or SMA connector. But what chip does this use? It's not a dedicated FM stereo encoder chip is it, it's a SOC or FPGA or something like that isn't it? Hope the Firmware is updateable. So e.g. they can "fix" the output level... And it would be so cool if they offered it also in a version with al those GUI controls as buttons and knobs on a box with LEDs and a larger display. Guess ELV just got another customer :-) Thanks for the thorough review.
The actual chip used for the generation is an fm transmitter chip, the Si4711. The output is one of those TV sockets (not RCA), which is inconvenient, so I may change it to BNC. As for the levels, I also think it is lacking there, but I’ll see how it turns out in actual use. I may need to build an L-Pad for the impedance conversion and even a further attenuator. I’m not sure the level can actually be further reduced via software. I don’t know the chip well enough to be able to answer that.
Looks good Manuel, I am interested to see it work, I probably wouldn't use one but very interesting nevertheless. Looks like they don't ship outside the EU 🤔
The RF output levels are MUCH to high for any FM stereo alignments. In order to test and adjust most vintage FM receivers/tuners the level would need to go down as low as 15 dBuV. Even the lowest level possible on this unit is too high to align an IF section. This would be a great alternative to some other FM generators if the output levels were proper for the designed use. As it is now, it’s mostly useless.
A couple of things . Saying its simple is pointless it may be simple for you but you saying "its simple " doesn't make it so and a demo in operation would have been more useful than showing how to check boxes on a GUI .
I dont see the benefit of this thing over a PLL stereo FM transmitter you can get from china for a few bucks. Oh yes, they dont have nifty app control and you have to pay for them. Freebee here freebee there, sponsored by this and that company... This channel is not what it used to be
Nor are some of the viewers, it seems. As regards sponsorships, you must really have a really low opinion of a channel if you believe the opinions will be compromised by the fact that someone offered me a device that I was going to buy anyway. I think I have a solution: don’t watch this channel any more. bye
Don't bother trying to order one of these as elv won't supply any country outside Europe Won't supply UK either, their excuse is something to do with taxation. (Read, bull...) It's funny how thousands of other countries manage ok!
Thank you for presenting the ELV SUP3. Thanks to this device, I will save a lot of money when equipping my hobby radio workshop.
👍

Nice! I will add it to my tools-to-buy list. Looking forward to you showing it in action and how you deal with the 75 ohm to 50 ohm conversion.
👍

This device is intended to be used on FM receivers in the 88 to 108 Mhz range and they typical have 300 balanced or 75 ohm coxial inputs.
What about a Silicon Labs Stereo Encoder chip which just needs a few extra components.
That's a good bit of kit, I was looking for something to do the same thing myself.

Cheers,
I was told they ship worldwide.
I would appreciate it if you could tell me the connector specifications of the cable connected to the RF output connector.
It’s called an IEC connector
Is there anyway to get this in the US?
I’m afraid not. They only sell within the EU.

Looks to be a good piece of kit, such a shame that we're no longer in the EU. Look forward to seeing you use it, regards, Tim
👍
Looks interesting and looks the part. For someone that does it for a hobby it is ideal.
👍

As I’ve actually got more than enough output level to spare (I may actually need an attenuator), I’ll probably build a resistive L-pad.
Can it output an MPX signal to align decoders? Typically the Saba ones I’m working on need about 1v p-p input.
The MPX signal, if I’m not mistaken, is at the IF frequency. This one emits a signal at the FM frequency itself.
Looks like a nice kit, and easy to build for sure. My first thought was that it came with a bag of components and a empty PCB.

@@electronicsoldandnew Not that easy to order from ELV.
Seems they only ship to mainland Europe. Contries in Scandinavia is not on their list. Bummer.
Any idea of the distortion level from this?
No, but it’s definitely lower than any distortion the receiving circuit will introduce.
Is the ‘crawler on the oled something you did, or did ELV do it for you? I would find that annoying. The screen is busy enough without it.
No, I did that 😃
How do I get this in USA?
I can only think that you should contact the company and see if they ship there.
Very very interesting
👍
Looks good Manuel, I am interested to see it work, I probably wouldn't use one but very interesting nevertheless. Looks like they don't ship outside the EU 🤔
I’ll be using to real soon. I actually spoke to them and they apparently do shop worldwide.
@@electronicsoldandnew OK, thanks Manuel 👍

They give you a 99% populated board but the battery compartment you'll have build yourself :-) That must be the German sense of humor.
😃
X-ray Tony, gave you a nice cameo
Yes, It’s quite a thrill to get one of my personal gurus doing what he did 😊
For £70 it looks like a bargin thanks for the video.
pleasure
Interesting device...
👍
elv is amaing
👍
Excellent product for FM alignment but no go with Australia delivery unfortunately. Shucks!

I will be demonstrating its use in actual alignments, as I mentioned in my video.
