Radio reception
Permalink  

My old coaster had a wis bang radio with all sorts of connectivity but would only pick up one fm station. It was always a good reception even in isolated areas where my radios normal struggle. Spent nearly a full day removing the old aerial (had to pull dash as whoever fitted it thought it was a good idea to wrap up all the wiring with it). Reassemble the dash and still only had one fm station no am. Replaced the radio today and bingo, about 20 channels. I just put this up because I have never seen this happen before, be interested if it is indeed common and what is the cause

cheers

Have you been able to pick up any AM stations? Their signals seem to travel further than FM.

the original radio would pick up one fm station from fm1,2 3 and no am stations on am1 and 2. Put the new radio in and received about 20 channels on fm1 and a few on am 1 without moving the coaster which is parked in a colorbond clad shed

Could have been a faulty antenna cable/plug/connection.

Radios differ in receive "sensitivity" and car radios are often deliberately made a bit "deaf" in order they don't pick up too much noise and distort the wanted signal.

Also check whether the "bad" radio has a switch or menu setting marked "DX/Local" or similar - DX setting makes the receiver more sensitive whilst Local makes it less so.

Hi Mike
Changing th arial was the first thing I did, no dx switch. Had a reasonable amount to do with radios over my time, hf, unf, cb and common old radios and never seen any thing like this
cheers

I'm curious. Sounds a lot like the programming has somehow locked up. What is the make and model of the radio you pulled out ?

Is the Coaster or radio an import with different frequency ? If it was this fixes your issue . FM Frequency extender https://rover.ebay.com/rover/0/0/0?mpre=https%3A%2F%2Fwww.ebay.com.au%2Fulk%2Fitm%2F123878107515

When scanning for stations it scanned all the normal Australian station numbers, would stop sometimes where it should have picked up something but nothing auditable, when scanning am it picked up the normal crackle but nothing strong enough to pick up a voice. Its in the bin now so it doesn't matter, just seems weird.
cheers

ps normally the strongest station locally is RN (radio national), the only one this would pick up was Christian FM which is not a strong station normally
Maybe its telling me something biggrin

Components die or become less sensitive. I would guess that the rf amplifier was faulty.
Fixing would be expensive if you found someone capable and they could get the replacement parts.
Basically it is a non-repairable item.
