Re: 3 Inch FSL Tecsun PL-380 Model

Upon closer inspection, the 2 wires coming out from the radio case, that are both inside the shrink tube,
were used. The 2 wires are still soldered to the circuit board,inside the case, a friend did this for me.
I believe there are more than 36 total turns of the Litz wire that have been wound around the bar assembly, my windings. The 8 ferrite bars are lined up as close as I could get them to perfect.
I'd say it  looks like the Litz/ferrite assemble need redone, and soldered to the wire
from the shrink tube again.

Jerry,

From an eyesight point of view, the most challenging part of that project was to solder the two 250/46 Litz wires onto the two PL-380 circuit board terminals. Possible problems in that process include cold solder joints, solder bridges to adjacent connections, fried components and/ or separation of the connecting foil from the circuit board. I can't really tell you how much it would cost to repair (or even if a repair is practical) without looking at the exact problem. If some components are fried or if the foil has separated from the circuit board, it may be necessary to order another PL-380 to correct the problem-- which isn't a very practical solution. Cold solder joints and solder bridges are easy to correct (as long as the original circuit board terminals are intact, and no parts are fried), and the rest of the antenna is fairly straightforward to work on, as long as the recommended parts were used. But before any repair is attempted (or repair cost estimated) a visual inspection is necessary to diagnose the problem.
