Re: Completion of 7.5" Loopstick Tecsun PL-380 Article

Guy Atkins

Hi Gary,

Your 7.5" PL-380 loopstick article is superbly detailed and clear. Hopefully it will inspire even the "DIY-challenged" Ultralight enthusiasts to give it a try.

If the Fine Tuning's "Proceedings" series of books was still in publication, I and the other editors would be clamoring to include your quality article! It's definitely up to the level of detail and information we were striving for in each article & review for the intermediate and advanced radio hobbyist.

Well done!

Hello All,

For those interested, the construction portion of the "Heathkit-like" Tecsun PL-380 Supercharging article has been completed, and is available for download at Before publication in the club bulletins, a short "testing and operation" section will be added (which is still being written).

Included in the 20-page article are detailed procedures to construct an install either a 7.5" Medium Wave or Longwave loopstick into the Tecsun PL-380 circuitry, as well as many Photoshop-enhanced construction photos to make each step as clear as possible. Both of these loopsticks have been successfully used by many DXers on both the Medium Wave and Longwave bands, and both of them provide a very major sensitivity boost over the stock PL-380 loopstick.

Although the detailed installation procedures apply for the Tecsun PL-380 model, these Si4734 DSP chip-optimized 7.5" loopsticks will work just as well with any of the Tecsun DSP models, such as the PL-310, PL-360, PL-606, PL-505, etc. The orange plastic loopstick frames may also be lengthened or shorted to fit the cabinet surfaces of these other models. Hopefully the article will motivate a few DXers to take up their soldering irons, and discover a new level of Ultralight radio DXing excitement!

73 and Good DX,
