Re: Tecsun AN-200 = Sutekus

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!

Hi Peter
Yes, that is impressive. I found this one:
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.
