[IRCA] New "Pest Control" 4.25 inch FSL Tecsun PL-380-- "Heathkit-like" Construction Article

[d1028gary@xxxxxxxxxxx]

Hello All, 
 
A second FSL-powered Tecsun PL-380 model has been developed with sensitivity and selectivity comparable to the original 3" Bar FSL model introduced in December-- but with a greatly superior nulling capability added as well. This model has been specifically designed to cut pest stations down to size-- and does so with breakthrough effectiveness. 
 
Using the commonly available 62mm Russian surplus ferrite bars, the model features both an isolated FSL coil and a shielded ground for the Litz wires. Breakthrough FSL sensitivity is augmented by the PL-380's Si4734 DSP chip, providing the triple advantage of superior weak signal performance, razor-sharp selectivity and exceptional nulling function. As with the original hard-wired FSL PL-380 model, the radio's internalÂSi4734 DSP chip tunes the FSL antenna for maximum sensitivity, so there is no need for the DXer to peak a variable capacitor. Each frequency tuned in on the PL-380 is already peaked for maximum sensitivity from 521-1701 kHz. A photo of this new model is posted at https://app.box.com/s/5r95oxc9v24vm9hbpe2w1g800lbt4d3b 
 
The full 15-page "Heathkit-like" construction article has been uploaded to http://www.mediafire.com/view/je2v6xorlnjmmbo/4.25inchFSLPL-380.doc 
 
Good luck to all who take up the challenge! 
 
73 and Good DX,
