Poor Radio Reception - possible solution

DJAndyB · 6th April 2009, 22:33

Hello,

Since fitting my new Alpine head unit the FM reception has not been as good as that of my previous head unit.

I have checked all the connections but the reception remains poor.

I believe my facelift ZTT does not have an aerial booster/filter fitted

(scrapped as part of project drive?).

On that basis would fitting one of these be a solution?

Many thanks

Andy

If it worked before ... it should work now. One possible place to look for is the continuity of the aerial element with the centre pin of the aerial plug (that goes into the radio)... Also check that you have no continuity between the inner and the outer part of the plug...

There could also be a problem with the receiver circuitry in the radio,,,,,,, WCS

Sounds like the Sensitivity and Capture ratio of new unit is not as good as one taken out.

Refitting removed items such as Diversity Amp etc not that straightforward
as you also had twin Aerial feeds from another section of rear screen etc.
The parts are not cheap unless sourced secondhand.

Make sure you are not picking up interference from the aerial lead and Heated Screen supply,
you may have to rerun or screen better.

Cannot comment on the unit you show to be honest,
quite often as in TV reception, Rubbish in Amplified means rubbish out. (but if signal is clean could well help, as not to expensive could be worth a punt).
