Whether the problems are due to the radio, or the cars antenna system has not yet been decided, but we'll get there in the end.

Note to Mark:-

If you are thinking along the lines of reproducing these for the masses, you can get those components for pence. There is nothing critical about the layout of the PCB, so maybe you could do without it and assemble 'dead bug' style? Just solder the correct component leads together and pot it in epoxy.

Harry,

Wasn't thinking about a mass production , but if someone wanted one I would put it together..

If enough people wanted them then maybe we can look at something along the lines you are suggesting...

But first things first..need to see if it works !!

Harry,it seems hit and miss to me whether the radio reception/TMC is of an acceptable standard on the current batch of DD's.I use both FM and AM,and with my present headset it works perfectly.I fully intend to order from Sean at some point this year but not untill i can be sure the new DD offers at least the same or better quality radio reception than that i already have.I also need fully functioning TMC to aid the navigation.

OK guys,

I installed the unit today and it WORKS !...

Had ZERO reception on AM with it OFF and then 5 or 6 stations with it turned ON...Still not what I would call great reception but it wasn't bad at all at least for AM.

Similar for FM, however I will need to test next week over the M62 and then again in Scotland to be 100% sure of the FM difference but the signs are good...

As soon as I can get my addy verified at You Tube I will upload the vids so you can see for yourselves... !!!

Lets wait until I have tested more on the M62 & up in Scotland / NE of England madone and then I will make it available for people should the wish me to make one for them...

At the moment they come it at just under £18, buying in bulk I can get that down to about £13 for the kit or £15 with the amp pre assembled..
( Which would cut down on the timescales ! )

Add on a couple of quid postage and can get them in for say £18.00

I don't mind putting them together free of charge but if you wanted to make it £20 per unit I would be fine with that..

There's always the suggested option of sourcing the parts and just soldering together and sticking into epoxy but I would be happier using the proper boards..

1st things 1st..let me give this a proper test over the next couple of weeks and then see what's what ...

Cheers

Hi Mark,

Your experiment compared the pre-amp unpowered versus powered, with it in the antenna feed in both instances. In the antenna feed, but unpowered there is bound to be some signal loss compared to direct feed.

Despite this, your AM sounded very much better than mine, which suffers a kind of repetitive digital rasping noise.

Well done Mark,looking and sounding good.

Hope the mobile testing gos well.
