My father just recently handed a Sattelit 2100 down to me that he bought in 1979. It is in the final configuration with silver knobs, has never been mistreated in any way and is still working flawlessly on all frequencies. The number of stations one can receive with jus the build in Antenna and the FM-sound is remarkble. AM-radio unfortunately has made quite a decline here in germany because more or less all stations have been shut down by the authorities, options to listen to it are therefore limited to night hours and some foreign stations. I consider myself very lucky and I feel like beeing back in my teenage years again, listening to the radio that was always playing in our kitchen when I was a child.
I was cursing watching the RUclips adverts for an unknown video that had started as soon as I switched over the TV, then suddenly I was in heaven as I saw it was another Satellit 2100 series from Mr Caldeira .....I got my first 2100 last week and thankyou, your previous series was so helpful! Can't wait to see what this one turns up!
Hi Manuel I am very grateful to you for having done such thorough work on restoring these old radios. I have little electronic experience but with your guidance have made progress on several old receivers and recently radios. I bought a Grundig Concert Boy 1100 and was impressed with the quality of the sound. It was as filthy as your 2100 but was very cheap (£10) and much to my surprise was working when I tested it. In fact the only thing that needed doing was using dioxit on the push buttons and giving it a good clean. I saw your work on the Satellite 2100 and that encouraged me to seek one out. I just bought one which was again very cheap but was minus a switch top and was again filthy. It arrived this morning and I have given the buttons a good clean and used Deoxit on the switches. I suspected that some of the radio might work and after a bit of work all but the long wave were coaxed back into life. The Short wave does not have many stations until the evening but they are all working and now it is 7.00pm there are plenty to tune into. Medium wave is good but FM is spectacularly good. I heard you saying that you were getting some decals done. Do you by any chance have a set left over that you might be persuaded to part with? I can see that the dark grey paint is scratched in places and I would like either to remove all the grey and go to silver or reprint the grey. Thanks again for the encouragement you have given us all. John
It’s good to know that my videos served as encouragement for you. That’s the main purpose of the channel. I have to confess that I haven’t done the decals at all. I got so used to using it as is that I simply forgot to go that extra step. It’s quite simple however. Just reproduce the texts on the radio onto a drawing program, get the spacing correct and try to use the font that best matches the original. Then simply print that onto a water slide decal sheet that you should find at your local stationery supplier, and you’re good to go. Best of luck with your journey. It’s a catchy bug, so I’m sure you’ll find more radios to work on.
Another Satellit Manuel, you will be the Satellite guru. I wonder if the radio had been knocked to dislodge the tumbler cards, they seemed pretty secure.
6:22 is exactly why I resist the urge to operate any rotary switches / band selectors on anything that I haven't opened up and given a good inspection on first. I've found quite a few items I could have damaged worse if I didn't take a good look before hand. I've also found loose hardware wedged onto PCB's, a broken AC power terminal strip from a transformer that dismounted itself, all sorts of things that could have been a lot worse if I tried to plug it in and started to twiddle with everything. I hope all goes well in the restoral, but I am sure it's in good hands.
hello friend, I have exactly that model all black. I have found the selenium rectifier and the electrolytic shorted, I have changed for current rectifier bridge and new filter. something happened, that the voltage (+) is lost along the way and 3v arrives at fi am. I will follow your videos to see if I solve it. thanks for sharing experiences.
Hi Manuel ! Thank You for the interesting video like always :-) I believe that the broken part belongs to the body at the bottom right side, You can see there the white plastic behind. Good luck and go on ! :-)
These Satellites are nice collectables. Its also fun to do some DXing while walking in the woods with a simple long wire antenna :D By the way, since you are using the "SUP3 HQ Generator" i bought one too. Its such a great tool! Oh and another tech-question for ya: I've got some old radios with "repair attempts" already "done". Thing is, the VHF Band is all over the place. I have the full manual for alignment and stuff. I already did the 10,7 MHz Part and now i am stuck with the 94 MHz (mid); 89 MHz low end and 100 MHz top end. The problem is... all the trimmers and coils are misaligned. Every single one of them. So it seems there is "no chance" to tune to 94 MHz if 89 MHz and 100 MHz ar misaligned already. The manual starts with "Tuner IF Alignment - 94 MHz" which wont work. So... do i need to do it... backwards? Starting with 89 MHz -> 100 MHz till both of these fit and then 94 MHz? And yes, the string and stuff is set correctly. Its "just" the coils and trimmers are all messed up. I have all kinds of generators and oscilloscopes if needed. Best wishes from germany!
Hi Kevka With the FM RF all over the place you need to try and find it somewhere on the dial. Set the tuning to mid-way (middle of the dial) and tune the SUP3 to try and find what frequency is being received there. Start at the lowest frequency and adjust all the way up to the end. If you don’t get it at all in the middle of the dial, tune the receiver to the left of the dial and try again. If you don’t get anything there, try it with the receiver times to the top end of the dial. You probably have to feed quite a strong signal. Once you “get something”, you can slowly try to move the frequency into the correct range. I had that before and ended up just adjusting all the tuning lugs almost randomly until I found the signal on the dial, then slowly started adjusting to move the range until I got it right. It’s rather a slow process if you don’t have some other equipment like a spectrum analyser (which I don’t have), but very satisfying when you finally get it right. Good luck 🤞
@@electronicsoldandnew Big, big thanks! Its an old sovjet radio and its going to be fun. :D Now with some sort of a plan. It doesnt matter if its a slow process, i just want this beauty running :D Big, big thanks!
The one I have is the black Grundig Satellit 2100. It is the best radio I've owned to date. Luckily the problems I've had were few. I have kept all your video series on this radio for future reference. I'm interested to see how you get on with this one.
Manuel, Jose a lucky Person getting the Caldeira wizard to repair his 2100. Your original series was brilliant, having a 2100 as control to compare to Jose set should make this project go quickly. Did Grundig market there sets with different mains plug for each market or did one use AC adapters?
😊 probably a great distortion effect 😊 The guitar is feeling neglected, I’m afraid. However, our daughter should arrive this week (she’s stuck in Oporto airport due to bad weather in Madeira) so the guitar may get some use when she asks me to play stuff that she can sing to 😊
my dad left me the 2000 version. is there much difference when it comes to doing the alignment? where can i download the workshop/repair manuals please?
I believe the 2000 is very similar to the 2100, with the exception of some of the tone control audio sections. The alignment should be the same. Try www.nvhr.nl for the service manual.
@@electronicsoldandnew Thanks for getting back to me. My Dutch is appalling, so emailed them In German as I couldn't find anything on their website. Is this where you downloaded the 2100 service manuals from?
Hello Manuel, I have this radio here also the 2100, and I have a function generator as well and later today a brandnew Hantek scoop; question: how can I transmit a signal from the generator to the radio on a safe way, without problems or do any harm to the radio or function generator? Thanks in advance.
Take the generator output and connect the signal line to a wire (a meter or so long). The simply place the wire half a meter or so parallel to the radio antena. Adjust the signal generator level until you hear the signal well on the radio. That’s the simplest way to transmit the signal. If you want to inject the signal into the radio circuitry itself, then you need to connect it via a small capacitor and use a much lower signal level.
@@electronicsoldandnew Thank you for your reaction, I prefer the way thru near the radio; and have now the scoop reicieved, Thanks again and i will try it by the way you did, a total new project for me, and is it always a good to replace the electrolitic caps on the audio board?, thank you
@@electronicsoldandnew It arrived. A black one. Its size surprised me! A bit crusty, but no missing button. After a quick inspection : Smell of burned varnish inside. Trace of case slightly smelt around the transformer ... Quick test on battery circuit with external 9V power supply and a big relief, it sings! So only the power supply seems completely fried.
Is the speaker a twin coil speaker? I noticed it has 3 connections to it. I didn't realise they had a twin coil speaker system in these :). Wish I could find one
The silver one is being run from the AC supply, and the black one from 9V from power supply. The former one is quite a bit higher voltage after rectification and filtering.
Quite different to how you normally do your videos. Enjoyed it, not that your usual way of doing these isn't enjoyable and if you were doing something you haven't done before I guess you would go about it much more methodically. This way is much more hands on without diagramatic explanation.
9:15 Amazing or amazingly finicky? This looks like putting separate radios on a switch rather than putting a switch in a radio! Also, I wonder how this came off in the first place: human intervention seems to be the most plausible assumption but could violent shock be ruled out completely? Speaking of which, I wonder what the reliability of this mechanism might be given that all the tuning circuits in it are subjected to a shock each time it is turned! Nope, not a fan🙂 If you think about it, even this kind of solution could have been better executed by simply keeping the tuning circuit boards stationary and have the selector sliders rotate around them (or just move laterally).
@@schorse1000 Thanks for this. Was that in black and white TVs? I've never seen one of these before this video so it struck me as a bit of an oddity/cost-cutting method.

The dislodged plates may have actually happened during shipping. Not sure. This radio was shipped from the IK to Madeira, so anything is possible.

It looks like it's clipping too low , on the silver one clipping was at 3,62Vrms , on the black one it seems you are about 1V lower. Am i missing sth?
