Re: Tecsun PL-360 7.5" Plug-in Loopstick-- Locking System


Gary - The PL-360 photo you gave the link to, and one or two previous ones come up as huge on my screen, and there is no tool bar to move the part of the photo I can see to center it over the radio. I can only see one edge of the '360. Maybe no one else is having this problem. I use firefox. But if there is an other way I could either see the whole photo in a screen size, or move it around so I can view what you are trying to show, then I could see what you have accomplished. Thanks very much for all your efforts. - FARMERIK

Hello All,

For those interested in this experimental project, the final design
challenge with the PL-360 7.5" plug-in loopsticks was to provide a rubber-based
system to secure the relatively large antenna and frame in place, to avoid
rotation in the antenna jack. Hopefully the same system would provide some
additional shock resistance for both the 7.5" loopstick and frame, and
reduce stress in the plug-in jack.

All objectives were accomplished by gluing a short section of 3/8" I.D.
rubber hose to the loopstick frame, carefully positioned so that the PL-360
whip antenna tip plugs into the rubber hose, whenever the custom loopstick
is plugged into the PL-360. Not only does this stop loopstick rotation, but
the system provides additional shock protection for both the loopstick and
frame, while dividing the loopstick weight between the whip antenna and
plug-in jack. The entire 7.5" plug-in loopstick system now feels very secure,
and well-protected against minor bumps and scrapes (a photo is attached
below, which is also posted at _
( ).

The PL-360's AM-DXing personality changes dramatically with these 3" and
7.5" plug-in loopsticks, which are great fun to play around with. For those
who have ordered new PL-360's and would like to try them, I plan to start
some "production runs" shortly (as time allows), and also post detailed
instructions for those DXers who wish to build their own. It's a very rare
opportunity to get a huge, self-contained AM sensitivity boost without voiding
the warranty :-)
