Re: Tecsun AN-200 = Sutekus

Hi Peter
Yes, that is impressive. I found this one: https://youtu.be/1VZAkDVPj_w
which shows a direct connection into a PL-330 having disconnected the internal ferrite rod. I tried this and was definitely able to tune a better signal, so maybe the two photos I posted earlier don’t show damage? I have to admit that I’d be a lot more confident about the whole affair if those ‘broken’ areas weren’t there! I’m toying withe idea of requesting a replacement.

Here's a video with an impressive signal boost using a Tecsun AN200!

I have similar experience to Jay Allen with the AN200. I wasn't impressed when I used it with a Tecsun DSP radio.
As Jay said there is an improvement but not spectacular. On the other hand, using an AN200 loop with an analogue portable or a PLL portable gave good results. It can certainly null noise and boost a weak signal. I had some good results with analogue pocket radios with the AN200. Unfortunately my AN200 and most of my portable radios are in the UK and I'm in Botswana so I can't make a comparison video. I have several videos on my YouTube channel showing use of the AN200 but I can't remember the titles. I'll try and find some. I have hundreds of videos!

Hi again Jay
Very many thanks for your input on this, it’s definitely appreciated. Not only your take, but additional info I wasn’t aware of. I do wonder if mine is damaged, as there appear to be two breaks (?) on opposite sides of the loop inside. I’m going to attach a couple of pics, and would very much like to know if they’re all like this or whether it is actually damaged. 

Thanks again

Hi again Peter
Thanks for the clarification! I also appreciate your take on this set, and as soon as I get mine I’ll update this thread.

Re: Etón E5

Peter 1956 <pe1etr@...>
 

Hello Drifter,
No, it means I'm from the UK and bought it there.
I do have some E5 videos.
The problem is I can't easily make comparisons with other radios, as I have to use a power supply with the E5, that does cause some problems to other radios.
It does lack a very narrow bandwidth, (just a narrow and wide switch for bandwidth), so it isn't as selective as my DSP portables.
The sensitivity is good, however, although the ergonomics are not good.

Yours is not an uncommon experience but it would help to understand some things about how these tuned passive loops work, and this will hep to explain why they seem not to work in some circumstances.

Except in the extremely unlikely event there is a broken connection in your loop, again, highly unlikely, they will indeed provide give a noticeable gain in signal strength, several db. So why does it seem it is not working for you?

The most common reason is that signal strength is not the limiting factor in your reception, but rather, signal to noise ratio. This is significant because in the later case the antenna will amplify the noise along with the signal, so the net result is no observable change. In the old days when radios had analog signal meters it was easier to see the signal meter jump when the antenna was peaked but with many radios with no meters or less obvious metering the gain may go unnoticed. But it is still there.

One other thing that happens with some DSP tuned radios like the PL-330 is that the DSP chip tunes the radios input to the ferrite rod and introducing an external antenna inductively may upset this tuning. I have experimented with my AN-200 and PL-330 and it is indeed trickier to see the improvement but it is there. You might try aiming the radio improperly to minimize the signal strength to peak the AN-200 more precisely, then re-orient the radio and you should see a higher signal level on the meter. Also try varying the distance between the radio and the antenna as you peak the antennas tuning ...you should hear a blip as you cross the proper tuning spot.

Re: Etón E5

Hi Peter
Does £50 mean you’re in the UK? Anyway, thanks for your reply. Mine doesn’t have the power supply, and I’m now hoping the battery drain is okay 🤔. I’ve just found a few videos on YouTube with one of them by an Englishman called Peter, that’s not you by any chance? How do you think it stacks up against current competition?
Drifter


Re: Etón E5

Peter 1956 <pe1etr@...>
 

Yes, I have one. Mine cost £50.
It is a bit quirky.
Mine is faulty. It continues to use power when the radio is switched off!
It works fine on the included power supply though, which doesn't cause too much interference.
You of course lose your settings when you switch it off.

Etón E5

FenDrifter
 

Hi all 
I just jumped on an Etón E5 on the infamous Bay. It was yet another impulse buy, but I’d been made aware of the reputation. Including postage it was £43.00 (app $58 US), which I was happy to gamble; can’t wait for it to arrive! Does any member have experience of this little beastie? Up until now the radio I enjoy using most is one I bought last week, a Panasonic RF-B11, fully analogue of course but sound quality, sensitivity and selectivity are wonderful, and hiss suppression is impressive. Not quite ultralight of course but worth mentioning I thought.

Thanks Isaac.
Yes, I prefer this method for logging. I don't really use an actual logbook.

Are these a good starter aerial for somebody who is only just starting out in the hobby?

Hi all
I just received today from Amazon a Sutekus loop antenna, thinking it appeared the same as the Tecsun AN-200. To my surprise it was both! See the below pics for explanation. In terms of effectiveness I am hugely disappointed. I was under the impression that it would enhance weak stations, but that wasn’t my experience. The first radio I tried it on was my Tecsun PL-330. I tried multiple positions all round the set, tuning the full sweep of the unit (not very great) in each position. The only effect I noticed was, in what I assume was the tuned position, was loud static. Next I tried a Philips AE-3405/01 with exactly the same result. I then tried a very cheap and nasty NT-999 which produced a minor level of enhancement and showing a surprisingly wide tuning range which separated on one occasion three stations within it’s sweep. So, I don’t feel I can send it back, because it does actually work although I’ll probably never use it again. If anyone else has a more positive experience with this I’d be interested to hear it. My own recommendation is to avoid it.

I love those videos, that is a really great method for logging and recording the stations you hear.

Hi Marc
What do you mean by a standard tuner please?

I have a "true" tecsun.

- It tunes very fine, so don't turn the wheel too fast.
- connect it to a standard tuner ...
