Volvo radio frequency interference
When out operating HF mobile, I noticed that certain models of Volvo trucks and some high-end Volvo SUVs were radiating significant amounts of radio frequency interference. Many other operators are noticing this. This video demonstrates the interference as I drive past a Volvo truck.

MFJ 1026 demo
มุมมอง 4.7Kปีที่แล้ว
The MFJ-1026 is a radio frequency noise cancellation device. Your main station antenna passes through the device, and it also has an auxiliary 'noise' antenna input. The noise antenna is deliberately sited to pick up the man-made noise from nearby sources. By careful adjustments it is possible to phase out at least some of the noise element, leaving the wanted signal which then passes to the ra...
Falklands invasion contact reconstructed
มุมมอง 471ปีที่แล้ว
On 2nd April 1982, Argentina invaded the Falkland Islands. One of the first ways that the UK found out about this was through a chance amateur radio contact between Bob VP8LP (in the Falklands) and Laurie G3UML who was operating the BBC amateur radio station in London. Exactly forty years on, on 2nd April 2022 in the BBC's centenary year, the BBC Amateur Radio Group used the special callsign GB...

    I appreciate the time you took to make this video. I know you have the very best intentions. I have looked at this item and it is costly. It's expensive. 'In my opinion' it isn't worth it. I understand you could now hear people speaking because of the drop in noise. But, you won't be able to communicate with them because, no doubt, they have approximately as much noise as you. 'In my opinion', for the $400 CDN this is going to cost me, this is not worth it, at all. Turning down your receive gain will get you further because, at very least, you'll be able to communicate with the person you're hearing.

    Thank you very much for this presentation! I am contemplating the same antenna. But I'm also contemplating the DX commander vertical antenna. So a critical question I would have from you - is if you had a choice between the loop antenna and a DX commander vertical - which one would you choose - and why? Sincere thanks!!!

    Steve, at 5:20 min you are talking about the height the antenna should be above the ground. As an absolute newbie, I would like to know if this antenna is supposed to be mount more or less close to the ground (like in your garden), or if it is also OK to mount higher up, like for example on the fence of a balcony ~10 above the ground.

    Well done Steve, a very detailed demo with some very good tips. I have a baby loop and a midi loop here. I did some trial tests on the baby loop over a 2 week period and was happy with the results. I used the keypad to alter frequencies and found the forward and reverse directions to be very similar in signal strength. I did some tests on the 40m band on our local radio club net and found the baby loop to be omnidirectional and and rotating the loop had very little effect. I assume that was because the radio club boys were within 40 Km of my location so I guess that means the 40m band NVIS propagation is omnidirectional and DX propagation or more directional. I added Fair-Rite mix 31 suppression torroids on all cables - the coax, the rotator cables and the DC motor cables. Those ferrites were added at both ends of each cable to ensure they were all adequately choked. I'm using the same rotor as you and I would be delighted if it would rotate at double the speed to get to the target direction quicker. Thanks again, 73, Jamie VK2YCJ

If the antenna is in fully automatic mode and I scan the frequency for stations on the Icom with the VFO, the tuning of the antenna is also fully automatic, did I understand that correctly? Sorry if I'm asking such a stupid question?😢

    Hi Steve. I was parked in a layby activating a bunker the other day and noticed a similar noise. I had activated from that layby before with no issue, but this time I had S7 noise across all of 40m. The only difference was that there was an Artic right behind me. I moved a bit further along the layby and the noise decreased. The noise disappeared when the truck left the layby. I didn't think to check the make of the artic, but Rob G7RFO suggested it could have been a Volvo and pointed me in direction of this video. Many Thanks G8XDD/P

    Hm! Petty the gamma is heavily welded , trimming that would put you SWR in place. I dont know if that paste is good or bad , I would put it together fluss, and then protect it from outside with silicone grease , and then service it from time to time. How is the loop reacting to heavy rain and snow with the non protected capacitor? How are the "nills" in and out of the plane? and are they also offset like the beam heading? Would be nice if the loop was offered as a raw loop , and then you could put together your own controller , eg arduino Just a thought, Tnx es gl

    Good day Steve, thanks for the nice review. Due to the high Q of the antenna, I tend to tune the frequency of the antenna 1 kHz higher than the radio, when I'm in USB and tune the antenna 1 kHz lower when I use LSB. (I have the MIDI-Loop). I noticed that this gets my reading of the SWR exactly the same on the Loop-tuner and my TRX. On the part of issues with the tuning box of the loop, I recently got many times the fault: "Motor fail - no load". Initially, I checked all connections on the tuner, on my radio and on the antenna itself. I found some moist inside the tuning motor cable connection box, at the base of the antenna. It also partially corroded the wires of the connections there. I ended up getting rid of the terminal blocks there and soldered the wires together of the incoming and outgoing side of the RF choke that is housed inside that box. But it didn't solve the issue with getting "Motor fail - no load". Only after I swapped the + and - connection of the tuning motor, on the side of the "tiny little" plug that goes into the back of the tuning unit, it was solved. To this day (3 months later) the fault hasn't returned and I can enjoy the antenna again. 73 from Holland de PC7H - Roy

    Hello Steve, as mentioned by many other enthusiasts you have made indeed a very comprehensive and informative video. Well done! I am a former user of the babyloop antenna and I used it intensely for many years with success. Later on I sold it to a very good friend of mine which I regret till this day. However it is my intention to buy the loop again since this is the most ideal antenna in my space limited situation. The most remarkable fact of your findings was, at least for me, that the babyloop in your situation was more sensitive for DX signals in the opposite direction in comparison what is explained in the antenna instruction manual, i.e. not in the direction of the gamma match but the other side. At the time I used the babyloop I was not aware of this property or behaviour I simply followed the instructions give by Cirro Mazzoni. I would like to you see, and with me many other radio amateurs I presume, If this also is also the case on your transmissions. Could you do some other experiments for us and share these with us? I would recommend you to make use of the Reverse Beacon Network or RBN for short. You do not need any additional equipment connected to your transceiver. You just use your computer to monitor your results. You only have to give CQ in { CW / RTTY / PSK31 or PSK63 } on a certain frequency repeatedly by sending the following sentence "TEST de G4HPE TEST". Make it last for a few minutes or so and observe your results on the RBN main page. Turn the babyloop in exactly the opposite direction and repeat the same procedure again. I am looking forward to you reaction ( and your findings of course! ) Sincerely Erwin, best 73 de PA3FCB

    This video has the best illustration on the importance on how to ensure approximating the input levels between the signal to noise antennas. So many MFJ-1026 owners over the years didn't know about this fact and ended up saying things like this was a piece of junk, and etc. Most of them do not know the tuning process but starting by wildly spinning their knobs in search for a null. Little that they know that would not have worked. 😂😂😂😂
