RNS-510 AM Radio not working

[alexperkins]

Thats quite odd pete, as my AM reception is fine aswell using that adapter

What aerial have you got - sharkfin or beesting?

^ I know dude, agreed.

It's definitely my environment, as such. I ran the wires without the adaptor on the RNS for a good 9 months or so, therefore perhaps it damaged them at some point then?

Beesting btw. It sits too high though, I need to crunch the screw length

Hmm maybe try a new Polo aerial - they apparently give much better signal than stock in any case

Just to revisit this one.

I ordered and fitted this adaptor (£11):

Now, AM works perfectly.

This is exactly what I purchased CP.

Didn't make any positive difference so clearly some wires are lose or damaged somewhere else. Tad strange  

I upgraded to the RNS 510 (from RCD 500) about 3 months ago. While changing over I noticed that there were no plastic connectors on the 2 aerial wires. I then remembered that the previous owner mentioned he did have the RNS 510 in there so must have removed the plastic connectors.

Therefore the previous owner must have had them connected without the adaptor and I currently have them connected without the adaptor and work fine. So it sounds like your AM cable is damaged or disconnected somewhere along the line.
