- Hello fellow techno-junkies!,
-
- I have a NAD 4225 tuner. I've had it for about 8 months and have been
- mostly happy with it. I've had a annoying "fuzz" over the top of several
- weaker FM stations for some time now.
-
- I put this down to just bad luck and poor signal, since move the indoor
- dipole antenna around didn't help and using the external UHF ( Yes that
- IS supposed to be a "U" ) made things FAR worse. ( Dont worry - Ive had
- THAT discussion )
-
- Then about a week ago I switched on the cassette deck, which is DIRECTLY
- below it ( when I've got the $3000 the carpenter wants to constuct my
- "idea" hi-fi/video unit ( with NO glass doors ) - they will have plenty
- of room between them ), I got a very distinct interfrence !?
-
- I thought "but isn't the tuner grounded" - answer - NO! It only had a 2-pin
- plug. However, on the back of the tuner there was a _ground_ connector
- beside the AM antenna connector. So I hastily grabbed a bit of wire and
- connected this to the ground connector on the back of the amplifier.
-
- It worked IMMEDIATELY - No interference - no annoying "fuzz", even on the
- weakest FM stations!
-
- I poured thru the NAD manual looking for some reference on this, to no
- evale. It only talked about the _ground_ signal in respect to poor AM
- reception ( who listens to AM any more ? ).
-
- Has anybody else had a similar experience with FM tuners or is this a NAD
- feature? If it is they should at least tell us about it in the manual!
