Christos’ trusty Tecsun PL-390 started having a problem recently. He writes:

“My PL-390 can no longer shift from MW [mediumwave] to LW [longwave]. I left it without batteries for some hours in order to achieve a sort of reset, but nothing happened. If I press the MW/LW button longer than usual, then it start presetting stations.”

I suspect this could simply be a problem with the contact underneath the LW/MW button. Has anyone else experienced this problem or found a way to fix it? Please comment!
