I posted this in the Antenna forum but got no replies, so I thought I'd try posting it over here in Homebrew and see if anyone can help me. I have one of those white under-cabinet Sony kitchen radio / cd players. The radio uses a digital tuner. They have notoriously poor radio reception, and the internet is full of posts by people ranting about how Sony could sell such a poor radio. I thought I'd ask you experts if there's anything that can be done to improve the reception. I understand the power cord is used as the antenna. I've tried stringing-up an extension cord to the power cord, with no improved reception. Could I open it up and attach an external antenna? If so, how would I do this? Any ideas, or experience with this particular problem? Regards, In theory you should be able to do so -- you'd have to be able to identify the RF section of the thing and find the capacitors (or whatever) that are being used to couple to the power cord. In practice it may not be the antenna that's the limiting factor -- a crappy receiver is a crappy receiver, no matter what you do with the antenna. You might be able to go as far as putting in an external antenna with a preamp, but you may still not improve the receiver performance, and at that point you may have done enough work to have installed a _good_ receiver into a similar sized cabinet. -- Tim Wescott Wescott Design Services http://www.wescottdesign.com |
