Sony p/s noise in adjacent am rcvr

Nov 09, 2007 8 Replies

KV27V26 with Bose Wave radio sitting on top... when Sony is off, in standby, Bose receives severe heterodynes on lower AM sigs. Interference is warbly, wandering, varies with small line voltage fluctuations, but generally is overbearing warble sound on top of am signal. Definitely the Sony, as unplugging it's power removes the problem.



Bad cap no doubt... but where?



May actually be fairly normal for this switchmode power circuit to interfere with a nearby AM radio. You may need to reposition or re-orient the radio.

As the award-winning Bose Wave Radio provides rich, room-filling sound anywhere... Why not just relocate it?

The effect that you are having from the TV set is normal. It's time to re-locate the radio. Make sure it is more than about 5 feet from the TV set.

I love it!

ROTFLMAO!

Thanks for your appreciation. I was, of course, poking at Bose, and to a lesser extent, at the people I'd recently had a flap with other Bose's marketing and advertising.

I assume you're not familiar with "The Lady from Philadelphia". This is a reference to Lucretia Peabody Hale's "Peterkin" stories of more than a century ago. The Peterkins were not very bright, and sometimes took their trivial problems to the (unnamed) "Lady from Philadelphia", whom they considered very intelligent. She invariably offered a simple solution that anyone with the least bit of common sense should have seen for themselves.

My favorite is "The Lady Who Put Salt in Her Coffee".

Don't get him going again.

I know, and Geoff is a friend of mine here on the group - but it was still quite funny.
