I just found an article in an old magazine today about this sort of antenna... from 1970 😁. I also wonder why not so many people use it. And the results are fantastic, plus that I only have 5W to play with so a nice antenna helps a lot. 73, YO6DXE

Those are even better. Or even a 2N2219. Those are bigger and they don't seam to heat up as much as the little 2N2222. If it fits on the board is great 😁. 73, YO6DXE

Cam asa ar trebui da. Apoi majoritatea componentelor sunt recuperate asa ca folosesc ce imi pica la mana ( hi ). Intre timp am cumparat si eu o gramada de componente pana sa aflu ca in RF e un pic altfel si na, acum daca le am musai sa le folosesc.

Ecranata 100% nu as spune. Dar am lipit pe interior peste tot acea folie de aluminiu de o folosesc instalatorii. Este ca o banda de autocolant. Nu e mare lucru comparat cu o cutie metalica in adevaratul sens, insa vad va isi face treaba. Ma rog... isi facea. Acum Pititico asta este la YO6TJJ cadou asa de amintire 😁. 73, YO6DXE. P.S. Vreau sa fac la fel acum cu Pititico II... varianta de aici de pe canal la care i-am pus si amplificator audio.

Yep. Pretty much that's it. Keeping things simple is the best. I just wanted to ad those adjustable "tips" to help me adjust the SWR easier. Works like a charm. And I am re-installing it as we speak on the camper 😅😅. I was just drilling the holes for the cable earlier. 73, YO6DXE

In this video ? I can't remember I must watch it again.

Thank you so much. Still learning new things about this antenna. 73, YO6DXE

Have a look in the video description. I have a link to the blog article and I have the schematic posted in there. Is based on the Lidia Direct Conversion Receiver. Nearly the same circuit.

roWaves used to sell the kit but is no longer available. I had a spare one but I just mailed it to Miami some while ago as a present. Indeed it could be used as part of a transceiver. 73, YO6DXE

Ohh great. I guess now you will just have to put it in the band properly. If you don't have a frequency counter, just listen to the online SDR in Holland and adjust the receiver until you hear nearly the same thing on the 40m band. That is how I used to do it before when I had no frequency counter. It takes a little time, but it works. Also make sure the antenna has at least 6-8 meters minimum as is meant to work with a proper antenna and shorter wires may work if the propagation is great, but you won't receive much in the days with poor propagation. Let me know if you need help. 73, YO6DXE.

Ohhh mükemmel. Bu şekilde ayarlamak çok daha kolaydır. 73. İletişimi sürdürüyoruz.

@@dxexplorer Sputnik'i yaparken 470pf seramik kapasitör yerine 470pf multilayer kapasitör takmıştım ama bir kaç gündür radyo üzerinde çalışıyordum bir türlü ses alamadım bugün 470pf seramik kapasitör taktım ve Sputnik'i çalıştırdım sonuç olumlu.🙂

Ohhhh the 470pF in the oscillator circuit ? Glad it works now. Congrats hehehe. I am happy it finally works. I get these days too when things don't always work and usually is something you don't think it will affect the circuit much.

There will be a few changes to make, but it should work yes. I know a few VFO projects online that are using a similar oscillator circuit and the lower the voltage the better the frequency stability. I wouldn't go lower than 6v though. As for the audio amplifier, there are many schematics online based on transistors that run on 6v as well. 73, YO6DXE.

@@dxexplorer Thanks, I think I'd have to get some low voltage varactor, so the receiver would not have to have a variable capacitor.

@dolnoslaski345 Yes that too. I usually adjust the circuit to the varactors I have available, so in your case you must do the opposite 😁. I'm not so good in what may work on lower voltages when it comes to varactors.

​@@dxexplorerand circuit too. I am going to play with potentiometer values and possibly capacitor so it would work fine.

@dolnoslaski345 i don't have the time now with all the work building the new house... but later on I also want to try a version powered at 3v. But I doubt that it will be with varactors, unless is just to cover one band only.

Do you have Instagram by any chance ? I could send you a quick video. But it doesn't get stuck in L mode ( low power ) ... at least not mine. But you can change that from the settings or while programing the radio. Let me know if you can't figure it out. 73, YO6DXE.

I didn't got to test this but I was told in the past that usually thicker insulation on the wire helps in getting better results... so I guess is true. Thanks for this. Is good info to write it down. 73, YO6DXE

Excellent 👏. 73, YO6DXE

True... but those I already have since I am an amateur radio operator. So is nice to have something for the "broadcast bands". Technically and traditionally some of those should still broadcast... or at least some with like... emergency messages. I do hope I will not need this radio for that though 😅😅. I really prefer it for entertaining purposes 😅. 73, YO6DXE.

Salut Marian. Ehh in poza nu, dar in clip da 😁. Doar ca nu aveam antena aia traditionala si impamantare cum trebuie. Am folosit practic antena de la statia radio, iar in loc de impamantare am legat tresa de la cablul coaxial. Si totusi merge si asa. Ma gandesc totusi ca daca as folosi o antena cum trebuie si o priza de pamant bine facuta, receptia ar fi mult mai ok. 73, YO6DXE

Никогда не знаешь, когда эта штука станет полезной )). Ох, да, ты прав. Я тоже посмотрел и увидел много других интересных радиоприемников от них.

@@dxexplorer к стати, лично по моему мнению, на каналах подобных вашему, такие обзоры приемников полезны но должны заканчиваться полной разборкой и обзором его схемотехники)))))))

@@piterstein9625 Это неплохая идея. Но когда я вижу их такими красивыми, мне, честно говоря, не хочется их разбирать 😅😅.

@@dxexplorer да так всегда, но как правило любопытство и "мне надо знать как оно устроено", "может можно сделать что то лутше", пересиливает😆😆

Ха-ха-ха... я так делал, когда был маленьким. Теперь, когда я стал старше и увидел, как сложно заставить их работать правильно... если всё получится... Я говорю любопытству, чтобы оно позаботилось о себе, потому что я не собираюсь его разбирать 😅😅 😅

True 😅. My iPhone is in the trash since 2019 😅. Thanks Nigel. Already awake... back to work at the kitchen floor today. Have an amazing weekend.

Very nice radio indeed. I was honestly impressed by the quality for the price. 73, YO6DXE

The download folder is a zip folder ( compressed ) but is meant for computers mostly not so much for phones. There are apps that you can use to unzip that if you want still. But inside you may have PDF, TXT and JPG files. The ordering link seems to work perfectly as I just checked now: www.pcbway.com/project/shareproject/Sputnik_Regenerative_Receiver_0edb19a9.html

I have one for 7000kHz that I also want to test ( ceramic resonator ). The crystals I buy from roWaves as I know they order them from Mouser so it's easier for me to order from the boys instead 😁. I am really curious how well it works on 40m and 20m. 73, YO6DXE

@@dxexplorer with the resonator, I guess you could make a tuned amp frequency doubler to get onto 14MHz with it. Rowaves are local for you. Good to support local :-)

@MidlifeRenaissanceMan Yes.. I always prefer to support smaller businesses, local or not 😁. Not a bad idea at all about the frequency doubler. Is all new to me so is very fun because I have new stuff to play with and experiment 😅.

I only noticed that now 🤦🏻‍♂️. That was not supposed to be kHz 😅. Thanks for this. 73, YO6DXE

Hehehe.. nu nu... ma sti doar... fara digital pe cat se poate de mult 😅😅😅. E mai fain asa "la ureche" ... e palpitant 😅😅.

Classic is what I love the most. Indeed it works, way better than I was expecting. Love it. 73, YO6DXE

Ohhhh I really love that feature as well 😁😁😁. Piece of cake to replicate a radio already programed. 73, YO6DXE

Old school is my nickname hahaha. I also love these simple analog circuits. I want to stat away from all this modern "digital" stuff. Old school feels more interesting and entertaining. Sometimes it gives you headaches until all goes well... but then it works like forever 😁. 73, YO6DXE. P.S. And it doesn't need constant firmware updates either 😅🤦🏻‍♂️.

In theory yes, but I guess that would be valid if I would be transmitting. Otherwise I guess there would be no common mode current. When it comes to placing the choke, that is what I also know, only that it doesn't always seem to do the job well ( on the EFHW, on the dipole is ok ). I have a feeling that maybe the toroid used and the material may have an influence on the SWR change. Is not much though. If with no choke I have a good 1:1 on 7.030MHz for example, with the choke it would be the same but on 7.060MHz. I am still studying this 😅😅. 73, YO6DXE.

Strange... maybe try to download it again. Who knows maybe there were errors when downloading. 73, YO6DXE

@@dxexplorer three times download today and is same. 😞

Nici nu am fost atent sa fiu sincer 😁. Nu prea ma uit la asa detalii hehe. O sa verific si revin. Acum sunt curios si eu hahaha.

Am revenit. Deci la mine pare totul uniform, poate doar un pic acolo in jurul tastei 8 sa fie lumina un pic mai slabuta dar abia ca bag de seama. In rest pare super ok.

@@dxexplorer Cel mai bine vezi pe întuneric. La mine 1,2,4,5 sunt un pic mai slabe, 7 și 8 și mai slabe. La alții am văzut rândul de jos mai slab iluminat. Aici mai au un pic de lucru. Mersi de răspuns!

@mihaidumbrava5498 da da pai noaptea am verificat si eu sa fiu sigur 😅. No... la mine par ok nu sunt diferente sesizabile majore. Trebuie doar trimis un email la ei la Tidradio sa stie de problema ca pana acum au s-au cam ocupat de orice recomandare primita de la noi. Asta e si motivul pentru care imi plac si I respect asa ca si companie. 73 si saptamana usoara cu spor la tot, YO6DXE

No no no... you just connect the coax to the BNC for example as normal... nothing unusual. You end up with one BNC in one side, and another one in the other side. One side goes to the transceiver and the other BNC to the antenna. Is just the one with the copper wire that you have to do the wire connections since you have two separate windings. One on the left one on the right. But there also you connect the BNC the same way as you would with a coax once you connected the wires together as in the video, because you end up the same with two in one side and two in the other side. I hope it makes sense, hard to explain I just woke up a little earlier 😅😅. 73, YO6DXE.

ох да, мои английский не очень хорош, но я вас смог понять))) в качестве balun 1:1 я бы советовал тот что мотается тремя проводами (ссылки тут размещать не получается) они у меня показали лучшие результаты чем такие из коаксиального кабеля или из двух проводов))) хотя в моем случае ферритовые кольца на которых я их мотал были далеко не лучшего качества)))

@piterstein9625 Хорошо, что вы поняли насколько. Про трехпроводной не знаю. Может быть, вы можете отправить мне электронное письмо со ссылкой, если у вас есть время. (это адрес электронной почты на странице контактов в блоге или в QRZ). Мне тоже интересно попробовать этот вариант. 😅😅

@@dxexplorer This balun can be easily found on Google by searching for “1:1 voltage balun” or “vk6ysf”. I took the design from the website of this radio amateur in the projects section. With the unnamed ferrite rings I have, this design showed very good results. )))

@@dxexplorer эту конструкцию можно найти на странице радиолюбителя VK6YSF в разделе проекты "BALUN 1:1 VOLTAGE".... надеюсь это сообщение модерация youtube все таки пропустит))))))

I think the first 1:1 RF choke I made was for my CB antenna... long time ago. It was made on a 15cm diameter PVC pipe and had a bunch of turns. It worked well but it looked like I have a pot hanging down from the antenna 😅😅.

@@dxexplorer imagine that 🤣. Yesterday I got my new transceiver yaesu ft-891. Now we can make contact whenever you will be ready 😁

@4L1LAT Ohhhh niiiiice.... maybe we can try this coming week. Not sure when I have the time but I will let you know in advance.

@@dxexplorer no problemo😄. Good luck my friend 73.

@4L1LAT excellent. We plan it and we try a QSO. I hope we are lucky with good propagation too. 73 my friend.

Thanks so much my friend. 73, YO6DXE

Yes.. but I only use this one for tests since the nanoVNA has the same connector, otherwise I use normal BNC connectors. 73, YO6DXE.

Reading the first words made me think I may have a too strange accent hahaha. Ohhh yes is a nice lovely place... not sure for how long as I guess more houses will be build here in the future... so I enjoy it as much as I can now. 73, YO6DXE

Thanks so much. I also enjoy that one as well. It seems way more simple and with the latest tests ( off camera ) it also seems that is not changing much the SWR of the antenna as it is with no RF choke. So I think I will also stick to coax. 73, YO6DXE

@@dxexplorer I think the isolation is better for choking RF the coax shield does a good work. So you consider put another one at the beginnig of the line to avoid SWR bounce back? cheers (Ruben LU8ARM)

@RA-Arg I tried having one at the beginning of the line as well... actually I have been playing with it in all sort of positions... the best results I had with the RF choke at the end of the line. When I tried it at the beginning of the line ( at least with the EFHW antenna ) it was messing the SWR on all bands. Basically it was shifting the SWR up in frequency comparing to what it was with no RF choke at all. When it comes to the shield of the coax... indeed that is usually enough if there is a lot of coax on the ground especially. But if the coax is shorter or not much on the ground, then the RF choke comes in handy. I remember I tried a vertical last year and I always had bad reports ( I was using only 3m of coax ). As soon as I put the RF choke at the end of the line... boom... good reports only hahaha. So clearly I was getting common mode curent coming back in the transceiver messing up everything. I am still learning about this but is fun. 73.

Less to worry about 😁. Especially when it comes to cheap ones that always have "surprises" 😅. 73, YO6DXE

1000:1 may not be a good idea 😁😁. 1:1 may help a bit to make sure we do not have the common mode curent that bothers a lot especially when transmitting CW with a metalic key... and we get surprises in the fingers 😅. Also the TRX is happy when there is no common mode curent coming back into the transceiver 😁. 73, YO6DXE

@@dxexplorer Try a 3dB 50 ohm attenuator between TX and ATU, this limits the range of SWR seen by the TX.

@FarleyHillBilly I don't use an ATU. But I have this written down for the future... you never know 😁.

@@dxexplorer Interesting book www.worldradiohistory.com/Archive-DX/QST/ARRL-Publications/ARRL%20Solid%20State%20Design%20for%20the%20Radio%20Amateur.pdf

Thanks so much Nigel. And good timing too. I was thinking earlier today to send you a TV show tomorrow instead of a radio show as usually hahaha. Yep... I just made a few more tests a little while ago and noticed that the coax version is influencing less the SWR that I have with no RF choke. So I guess I will do just the same. Less connectors to buy... more beers for me 😅. Summer in the camper is like on the boat with no wind 😅. 73, Nigel... happy Sunday my friend.

Haha... thanks so much Jason. Ohhh is not as good as it used to be. I left US in 2018 so I kinda "forget" how to speak now and then. Hard to find the right words I guess 😅. 73, YO6DXE

@@dxexplorer Bah… nonsense. I understand you. That’s what is important. Truly. Keep doing your thing! I like your excitement in what you are showing us!

@jstoltenburg Hehe... thanks so much for everything. Ohhh the excitement comes probably because I feel like a 10 years old kids when playing with these. Always takes me back into my childhood when I was just dreaming at what I do today... and now I am pretty much living my childhood dreams. Good feeling and I am lucky to be able to do this.

Yes indeed. Actually that is the main purpose.. the preamp thing is secondary. 73, YO6DXE.

The circuit would be diferent but I think yes you could make a transmitter with a mosfet too. Basically this is just an oscillator.

Not sure if he was... or maybe my truSDX is not exactly as it should be as sometimes I have this feeling. I need to get a proper transceiver ... still QRP but I am searching for something old school. Still saving for an FT818 from Yaesu... love it. 73, YO6DXE

2N2219 and BD139 work pretty well. Unfortunately for the entire process I have very little time now. Maybe a little later in the autumn time.
