The S350DL may look like a digital radio, but it’s actually analog inside and tuning is prone to drift.<\/p><\/div>\n

Many thanks to SWLing Post<\/em> contributor, Ed, who noted my comments about the Grundig S350DL’s tuning drift yesterday<\/a>, and shared the following fix found on Jeff McMahon’s Herculodge blog.<\/a><\/p>\n

[…]The drift on AM was terrible! After 10 minutes, it is jumping all over the place – if you touch the radio, the sound mutes and the display goes nuts. I pack it up to take it back but then I decide to google the problem and find this:<\/p>\n

I do exactly what he says – I pull off the cover after unscrewing all of the screws (including the 2 in the battery compartment).<\/p>\n

Only the speaker is attached to the front. I remove the three screws from the display and then tighten the two screws on the tuning wheels. They were barely loose – almost not noticeable – so I was not too optimistic. I carefully got it all back together (the plastic pieces that hold the fabric handle on only go back on one certain way and were sort of a pain!). I cross my fingers, plug it in, and wow – a brand new radio. The tuning is perfect. Zero drift on FM and AM. AM sounds excellent.[…]<\/p>\n

I have an earlier Grundig S350 that I bought at a hamfest years ago which had an easily-fixed power problem. For $20 it makes a nice bathroom radio and it sounds great, especially on FM.<\/p>\n

BTW, I found schematics for it on radiomuseum.org<\/a>, which is a great resource for radio schematics.<\/p><\/blockquote>\n

Thanks for the tip, Ed! I think I’ll crack open my S350DL later today and give this a try!<\/p>\n","protected":false},"excerpt":{"rendered":"
