Almost yes. I have half of it written and I was working on the drawings and details. I will finish it once I get home as I will also make a new video as well since I am planning to build one more that weights less.

I go home this Friday. I come back but not sure when. Maybe the end of the month.

I tested that in the part two of the series.. a video or two back. It didn't perform as great as this time. Maybe the propagation was not the best also.

The location for me is more like heaven on earth. Sadly I must return home at the end of this week after three weeks spent here. But... I will return 😅😅😅

@@dxexplorer I really like place. free from everyone and everything. from civilization 🤣😁. good luck buddy

@4L1LAT only me and the bear here 😅😅😅

I hear them all the time especially on the 40m band. Maybe some of them but there are many still on air. I am also exited to get home and build the final version with the PCB boards I just received 😁😁. 73, YO6DXE

I really have to try building a loop as well. I never tried one.

When we finish the radio room here, I have a feeling you will see a lot of QSO's from here 😁. About the rain and the conditions on propagation... ohhh no I was not joking at all. I think is because in here is like I am in a pot all shrouded by mountains or something, because when it rains even the phone signal is extremely bad. One network dissapears completely. The EFHW barely receives something as well. Not sure why but it is what it is. Maybe the radio waves are scared of the bears we have around here haha. I will be back in Brasov at the end of this week and stay home for a while so maybe we get to meet. We keep in touch. Have a fantastic rest of the week. I get back to work here so we finish the roof before I leave. 73, YO6DXE

Perfect for this place as we must hide it in the attic to keep the place same as it was but still have a bit of radio fun 😅😅😅.

If you understand propagation and the fact that technically with the conditions I had I expected to hear nothing... indeed it was interesting results to me. The hiss was mostly on the 40m band... on 20m it was full of signals.

Stop hateing....

🙏🙏 thanks so much for watching. I can't wait to build the final "fancy" version. 73, YO6DXE

Indeed. I switched to the EFHW really quick after I stopped filming and it was nearly equal. I did not expect that at all considering that I am surrounded by mountains.

I didn't had the chance to film as we were rushing to the city so I can edit and upload the video but I listened on the EFHW as well for a bit and the Mini Whip was nearly equal. I was not expecting that 😁😁😅😅. 73 and have a fantastic week Jason.

Thanks so much. Amazing place indeed in here. I found a website that sells both transistors before I left home, so I will order a few once I get home. 73 buddy.

@@dxexplorer i don’t think it’ll make a lot of a difference. But now I’m curious.

I am also curious. On the JFET I think it won't be such a difference as J310 can be replaced easily with other similar ones, but the NPN I have a feeling it will perform better because the antenna should resonate better on lower frequencies as well. We will see )))

Ohhhh thank you so much. I very much appreciate the advice. I will do it this way on the final instalation once we finish building the radio room. I will still have to hide it in the attic, but with a good ground I have a feeling it will work way better than now. Even though I am happy even the way it works now. I was not expecting it to work so well. Luckily here on top of the mountains there is not much interference from anything as besides the lights and the phone chargers there is nothing else here. 73, YO6DXE

Hi friend, yes this could improve receipton very much. If you want to compare sigs you can listen to WEB SDR Station operating with Mini Whip. If you listen to the WEB SDR Radio from University in Twente (Netherlands). (Google) They are operating with Mini Whip as you surely know? Another way to get more gain of the Transistor could be to connect two of them in Parallel. That should increase the Signal Strength also.... vy 55, Heinz, DE0RST

@heinzriedl6868 Ohhhhh the trick with the tranzistor i didn't know. Is it the JFET or the NPN ? I guess the JFET since the NPN is there just to lower the impedance. And yes if course I know about the SDR in Holland. Is the one I use for most of my tests as reference 😁😁.

Its the JFET which could be parallel connected. If you have no success with that please send me a note and I will send you J310 for experiments 😀 @@dxexplorer

@heinzriedl6868 Thank you so much. Ohh I will order the transistors when I get home. I found a store that has them in stock still. I really appreciate the help. Time to experiment a little more when I get home hahaha. 73, YO6DXE. Bed time here as in the morning, back on roofing work to finish here 😅😅😅

The schematic in the video was the original one I downloaded. I made a new one that is on the same page where you found the PCB board you ordered somewhere on the bottom of the page. That one should correspond to the PCB board. Let me know if its all good.

​@@dxexplorer Thank you! I've found it. Now I can tinker. I'll let you know how it works!

@uli_6830 Always a pleasure. Excellent then... let me know how it works. I am up in the mountains now but I was told my package has arrived so I will also build a final version when I get home. Meanwhile I will try to also find the original transistors. I just installed the one I made in the older videos here in the scouts camp. Seems to work like a charm so far. I will upload a video later on this evening if internet helps me 😅😅. 73, YO6DXE

Good idea. That I didn't try. But meanwhile I managed to change my phone number to some other network and I finally have internet. No too fast, but its better than nothing. 😅

I must ask the bear haha. I managed to change phone numbers. Using another network now and I finally have internet. Not too good but its better than nothing. You are right... let me try programing it in frequency mode. That may be the issue. 73 Nigel and greetings from Cioclovina. P.S. it only took me two days to upload this video 😅

It reminds me of the simplicity of the Baofeng, except that this one is WAY better 😃😃😃. 73 my friend.

It's mind's me of the baofang uv3r

@matthewt-ty33 I never had that one. I like it because it's really simple a kind of straight to the point. Easy to set up and use. And the most is that it actually has the power as per the technical description and on harmonics suppression it's perfect.

Woaaaaaa. Those are nice to bring back to life for sure.

@@dxexplorer Yes, it's great because all yjese old tranceivers are good systems. I have so many CB tranceivers like xtals 6 channels, and a very old tranceiver headkit with its external power supply, non fonctionnal bot able tu be restored. I love this old tranceivers. New items are not so good...

@francksylene1560 i also love old school stuff... all analogical. The new equipment its nice too... but it feels like I don't have so much joy as using an older one.

@@dxexplorer I'm ok for that, all my tranceivers are vintage ans analogic... And alwais a pleasure to use it. I dislike strongly new CB tranceivers with digital electronic circuits as tje SDR. Old CB are ok after 50 years, but in the future, digital tranceivers wont be ok after 20 25 years... This is the problem of digital technology and low cost components used in the new tranceivers...

@francksylene1560 I totally agree with you. That is why I am so much into older stuff. I always say... old is gold 😁

I don't really understand the company type part 😁😁. A picture of ? The receiver ? I have a few on the blog article about the receiver.

ممتاز

Indeed it is Russ. I also thought about building one that I could use either for 40m or 20m. Work in progress postponed for when I have a little free time. Love it so far. 73, YO6DXE

What kind of file ? I am a little confused 😁😁

Hi my friend. Have a look on the blog article about the Sputnik receiver on the blog ( dxexplorer.com ) you have all the details there. 73, YO6DXE

Sorry for the late reply. I have no phone connection here so I only have internet when someone else in other network shares a little with me haha. The 3 turns I picked by trial on error. I wanted to be sensitive but also not too much to avoid overloading it. Yes I made a version for 20m as well. I cand remember the turns number though. But I didn't changed anything in the circuit. Maybe just the value of the capacitor that is in parallel with the main coil. I think I used 14 turns if I remember well ( but I may be wrong ). 73, YO6DXE

@@dxexplorer Ciprian, thank you for your response. Don't worry if you weren't able to reply quickly. I finally made the modification with a yellow T50-6 toroid, with 3 turns for L1 and 16 turns for L2, and the Sputnik receiver is working across the entire 20-meter band. It’s an excellent regen radio, which has really surprised me. I uploaded a video with a test to my channel, 73!

Nothing as simple as I want so far. I am also still searching. This one also works but not yet perfect. Maybe this autumn I will have a little time to make it work as I wish it would. 73, YO6DXE

Thank you so much as well for watching. Indeed I also love it a lot. Really good sound to be honest. I was not expecting that. 73, YO6DXE

Thank you as well for watching. Really good tools. Happy to have them and what I have extra I like making gifts to friends so they are happy too 😁😁. 73, YO6DXE

I am sure is not exactly perfect. I am also still in the learning process to make more precise measurements. So far all I know is what I have learned from other fellow RU-vid creators that made videos on this subject. But this is the beauty of the hobby.. always learning more and better ways to do things. 😁😁 73, YO6DXE

@@dxexplorer 783 / 5.000 Hi, physics and electronics in particular, should be studied with books to be sure not to acquire wrong information unless you choose well-known names e.g. W2AEW who, thanks to his past jobs, also knows how to explain very well (suggested to all my students). The situation about videos in italian is dramatic due to a very low level of the youngest Italian OMs and also, despite this, they make and publish videos with the claim to explain what they have not studied. This is how myths and legends are born and spread: this is the reason why I have written several articles with the aim of fighting them. The links are on my QRZ page; sorry, they are still only in Italian: I hope Google can help you, if you are interested. 73s

I don't know to be honest. I have a really bad phone signal here and I am happy I can reply here. Nothing else really loads for me now. Usually you can go on their website on the product page and down low in the product description you should have a link to take you to the firmware page and it will tell you what is the latest one. 73, YO6DXE

I am also really happy about the way it works. Not as sensitive as the end fed half wave but they seem to work differently. The mini whip seems really good on picking up DX stations. I am also still experimenting with it but considering that the original design was experimented on by the creator for sure... I kind of trying to stick to the original design. I will also try to order the original transistors as I am sure that it will perform a lot better. Tomorrow I hope to make the part three of the video on this one as I am curious how it performs here in the mountains in the scouts camp I am currently in. 73, YO6DXE

@@dxexplorer Thank you! I have just replaced the capacitors mentioned. The reception seems better to me. Especially on the upper bands. Let's see what happens next. Have fun trying it out!

Maybe Google is not translating well... but I can't really understand the comments. What do you mean by remote reception ?

Is there a way to contact you for more information about this?

Still learning on how to make better measurements on anything related to amateur radio. The best part of the hobby is that there is always something new to learn for better results. So far I do things as I learned from 99% of the people doing measurements either here on RU-vid or in real life. As long as I am "close" and I have an idea how a certain thing may work or how effective it is... I am happy. But I never say no when it comes to doing it better. 73, YO6DXE

Ohhh cool that I didn't know hehehe. Thanks so much for the tip. 73, YO6DXE

Ohhhh thank you so much. Now I understand even better. I was close but now I am closer 😁😅. I just wonder as I see diferent opinions online... some say its better to ground the ground of the mini whip it self right there on the spot... others to ground the coax before going inside the house ( camper in my case )... and others to actually ground the coax right before it goes into the Bias-T. At the moment for my convenience I grounded the entire Bias-T box since is all aluminum and it was easier. The antenna is about 5-6 meters high at this point as as ground I use the entire camper since is all covered in aluminum... and I also have a bit of copper sheet underground with a wire connected to the aluminum sheet that covers the camper. So it should have decend grounding as it is ? Still it doesn't seem so sensitive as I expected it to be. Maybe something is not yet quite right. Trying to figure that out haha. Thanks so much one more time. 73, YO6DXE

@@dxexplorer Thanks for your kind words. If you mount the whip a few meters above your camper like you wrote with the camper being all metal that sounds like a good setup. The sensitivity of this antenna isn’t super good. I think the goal for this antenna design was a good compromise between sensitivity, signal to noise ratio and not being overloaded by nearby broadcast stations. I did see in your video that the gap between the copper pad and the ground plans in your PCB is rather narrow. I have it a little wider. The stray capacitance between the pad and the ground plane shorts the signal to ground and limits the sensitivity. Best to keep this stray capacitance as low as possible. All in all this is a nice antenna for a lot of experimentation and for sure everybody’s mileage will vary! Have fun with your build, looking forward to part 3. With regards to where to best ground the mini whip - with the outer shield of the coax being part of the antenna system - the further away from the mini whip PCB you ground the coax, the bigger the influence of the coax becomes as part of the antenna. I can’t tell upfront if this is good or bad. I used mine in the yard on top of 2.5mtr of PVC pipe on a tripod with the coax partially laying on the ground. I took no other grounding measures. Far enough away from the house the noise was low and although a little weaker the ham radio signals were clearly audible.

@robertvandersanden Ohhhhh I thought about the gap between the pad and the rest of the stuff. Ohhhh one more thank you then 😁😁. Yes indeed it looks like a compromise antenna... but I like it even just as it is. Is nice that it can cover so much and I don't have to keep switing antennas when testing all sort of receiver projects hahaha. Thank you so much one more time. And yes I will do the final install here on top of the camper when the PCB boards for the Mini Whip arrive and I do the final version. 73, YO6DXE

Yes of course you can. It will only be harder to tune so either use a really big diameter button or in case you have a reduction drive then that would be great too. I used regular potentiometers too until I discovered the multi turn ones 😁😁. 73, YO6DXE

@@dxexplorer Thanks!

@Mini-xi1wt Always a pleasure. 73

Thank you so much. Yes it should be a 1:1 common mode choke. But it only becomes effective is the pole of where the antenna is installed is metalic and grounded and the ground of the antenna connected to the pole. Mine is on a plastic tube so a 1:1 choke is ineffective. At least in the tests I made I see no difference. But on the other side, I am lucky because I am in the middle of corn fields with my camper and I do not have interferences. The noise level on the transceiver is down to S2... compared to the S4 I get if I use the EFHW antenna. The only problem I have is that the Mini Whip doesn't seem so sensitive even if at the moment is up 5m in the air. I know it becomes more and more sensitive the higher is installed, but I was expecting it would still work great even if its a little lower 😁. We will see now when I will also do the final install in the kids camp to see if I get better results. My grounding here is not exactly perfect either and I do not use the original transistors so maybe that may be one other reason. Still in testing mode now. I just finished designing the PCB board. I must offer a set to test it and see how that works too. 73, YO6DXE.

The coax was just simple RG-58... but I tried to buy one that was more flexible and also I left it out in the sun to warm up and become even more flexible when making the turns on the toroid. The toroids are both FT140-43 yes. Its better to use 240-43 or 240-31 even better. I used what I had available. The insulated cover wire is 0.5mm no insulation / 1mm measured with the insulation.
