I bought a new aerial as my bodged fix to snapped aerial was only getting me classic fm. with a new mazda £35 aerial I get no better, thought would be getting better reception than this!! Any clue why?

I am using genuine mazda aerial for bongo just fitted
Beat 600 double din radio (£350)
aerial fully up
Live in North Wales?

Is it an original Japanese radio?

They are on a different band to the UK broadcasts. They do overlap a wee bit - hence the Classic FM reception.

You need to either fit a "band expander" which is actually a "band shifter" to allow the Jap tuner to receive the UK frequencies, or chuck it out and fit a UK spec radio.

Hi
You lucky ol' sausage!!!!!!....That's the only station i'd listen to in the UK...over here you just get radio stations playing stuff called Chalga...it's a miserable cross between Turkish and Gypsy folk pop ....and every song sounds the same...to cap it all, every flipping TV channel plays the same, and the populace sits staring at Chalga Videos while they eat mind-numbingly AWFUL food
I'd kill for Classic FM :cry: :cry: :cry: :cry:
Cheers

Hi Paulinwales,

Very classy unit that you have,

Make sure that the extension connector hasnt come adrift on the cable from the areal to the unit,or is it a tuning fault.

Cheers

Sounds like you are very near a Classic FM transmitter and as Rita suggests there is a break or non connection in the aerial lead so only a stromg signal is getting in.

Ah, so a Beat 600 isn't an old Japanese double-DIN unit then.

In that case, indeed sounds like a duff connection from new antenna to head unit somewhere.

I'm told but haven't checked myself, that there is a connector in the co-ax aerial cable on the drivers side as the cable starts to rise from the dashboard up the side of the window screen, it can allegedly come apart if the co-ax gets pulled. As I say its been reported but I haven't been able to spot the connector from a brief look whilst doing other work under the dashboard.

With the aerial cable un-plugged from the radio itself, you could check that the resistance between the aerial itself and the inner core of the co-ax at the radio end is zero resistance, also that there is zero resistance between the screen of the co-ax and chassis of the van, finally check between aerial and chassis and that should have infinite resistance or very high (above 100KOhms) as a minimum. If all three are correct then it is unlikely that there is a fault with the aerial. If you can run the radio out of the dash itself you could check to see what reception you get if you connect the probe of a meter into the aerial inner plug and leave the other end free you ought to be able to get reception using that provided your not draping the meter wires over too much metal work.

the end cap comes off the dash so you may be able to get into to see there.

Ooh, that's interesting - I must check my join is OK. I have always had fairly crap reception.

Any idea what the bits in -6A01 are?

Found the connector (by pulling the end off drivers side panel) was fine.
Problem was there were 2 aerial leads and i had plugged into the most obvious one that had a bit of circuit board attached (band expander?) and some fenale adapter thingy comming off. By tracing the wires and running a bleep (circuit tester) test off the voltmeter tool ,connected the other aerial into the radio unit and all works well

Cheets all :)
