Hi Zacharias
Many thanks for info and links. I had a good look at the close-up shots of your antenna, and I could not see any marks similar to the ones in my two photos above, do you think mine is damaged please?

You could better turn the antenna to the maximum possibly signal by first finding the zero point in your radio Then turn by 90degs and doing the same on the loop

Thanks for that Kevin, all grist to the mill! I particularly liked the screwdriver idea, simple but easy, great!

In addition to using the loop completely standalone next to the radio (coupled to the internal antenna or passive), you can also connect an external wire antenna and ground/earth to what is normally the connection to the radio (1/8"-3.5mm jack). Space permitting, you will enjoy the benefit of a larger signal capture area with the longer wire and ground as well as using the loop as a preselector and inductively passing the frequency of interest off to the radio. i have done this with my Terk Advantage which is similar to the Tecsun/Kaito/etc. It works but does remove a bit of the indoor portability but is another avenue to explore. 
For temporary installs i have tied a ground connection to.a screwdriver into the soil and a wire tossed on a fence or tree. For more permanent installations, proper static discharge and good grounding rules apply.
i like using these commercial type loops as i can throw it in my luggage without worry about the loop wire snagging on something and coming apart.
Similar ideas like this are presented on crystal radio sites. A number of radios shown on these sites are definitely not in the ultralight category!

Allright Paul. Looks good. I look forward to this after the Nor-easter leaves the area.

Drifter, 

I have owned so many of these portables, but I remember the E5 well. I believe the one I had was a G5, and Grundig branded, but essentially the same radio.  Performance-wise you can expect it to be similar in performance to the Degen DE1103/Kaito KA1103.  I believe that they are very similar internally, but the E5/G5 ditched the odd slide-rule LCD setup.  You will enjoy it!

Portable Radio RXing Awards Program

Paul Blundell
 

Portable Radio RXing is an awards program for anybody interested in the radio hobby, which encourages portable operation in parks and similar areas.

 

Portable Radio RXing has been designed to make participation possible for anybody interested in the radio hobby. The rules are very simple, and the awards have been designed to be achievable. The purpose is to encourage portable operation in parks and other similar locations, making the radio hobby more public and allow radio hobbyists to enjoy the great outdoors.

 

How do I start?

Get out in a local park with your radios and log what you hear, it really is that simple. A log file is available for download on this site.

 

Rules:

These rules are simple and have been designed to enhance the enjoyment of this awards program and ensure fairness.

 

1) All Portable Radio RXing activity must take part in a public park, lookout, beach, mountain top or other such public location. All equipment must be portable and carried by the participant to their operating location.

 

2) No Portable Radio RXing activity is permitted on private property for award purposes.

 

3) 5/10/15 rule:

- You must walk a minimum of 5 metres from any motorised mode of transport for a valid Portable Radio RXing activity.

- You must log a minimum of 10 frequencies for a valid Portable Radio RXing activity.

- You must remain in your location for a minimum of 15 minutes for a valid Portable Radio RXing activity.

 

4) All frequencies must carry voice traffic. Data / paging frequencies are not permitted for award purposes.

 

5) All HF/VHF/UHF frequency bands are all permitted for award purposes.

 

6) Each location may only be counted once in a 48-hour period for award purposes.

 

7) Each frequency may only be counted once per location per Portable Radio RXing activity.

 

8) All decisions of the Portable Radio RXing administrator are final

 

 

Scoring:

Each activity counts for 1 point, bonus points are awarded for the first Portable Radio RXing activity at each location (to encourage Portable Radio RXing activity from different locations.) This adds 5 points to your tally.

 

Logging Process:

Below is an example of a valid log.

 

Awards:

Certificates will be emailed to all participants on the receipt of a valid log for the achievement levels below:

15 Activities

30 Activities

50 Activities

100 Activities

Actually CJBC 860 but yes 50 kw.

Re: First time am catch!

In addition to Zoomer you may be able to tune CHOQ (? ) at 860. They are 50 kw as well. It will be a zFrench language broadcast so you can ID pretty easily.  Comes in consistently here. Good luck. I’ve  tried to tune WOR in Boston with no results.

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

Re: Tecsun AN-200 = Sutekus

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 
Drifter

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.

Re: Tecsun AN-200 = Sutekus

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.

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.
