cheap-mans in-car DAB

right then ladies, gentlemen & children of all ages, this is the problem:
i love listening to planet rock & talksport (some would say i'm addicted) on my pocket dab receiver, but since i no longer walk to work (i have finally pass my driving test & got myself a little run-a-round) i now cannot listen to planet rock (cos it's not am/fm) & talksports reception is crap. i have tryed a tape to external headphone jack, but the reception kept going off due to the radio moving round, so i was thinking, would one of those cheap transmitters do a half decent job?

i was going to get a new radio, but atm there out my price range

any advice would be grateful

Cheers

You could go back to walking to work, thus reducing your carbon footprint back to what it was

That said an Ipod transmitter that uses the earphone jack should do it - I can't see why not

Dad bought a REVO to listen to planet rock in his saab. It uses an aux in port. Your tape adaper would work fine.

Saturday morning is only 6 days away!

Whenever I've tried to do this on a radio with separate telescopic aerial, the DAB signal strength immediately drops and affects reception, presumably due to the FM transmitter creating interference.

A device which doesn't have its own aerial and uses the headphone aerial lead as one will surely be even less likely to work since that same headphone aerial cable is typically used the FM transmitter to broadcast the transmitted signal, so will be injecting interference directly into the radio?

The best solution is surely to use a DAB radio with its own telescopic aerial, then use the tape adaptor or AUX input, otherwise you'll end up with poor DAB reception if relying on the headphone cable to act as aerial.

If the headphone lead is indeed used as the aerial then plugging a FM transmitter into the headphone jack could well cause problems. No headphones means no aerial means no DAB reception.

A couple of solutions spring to mind. The off the wall one is to buy both an FM transmitter and a mini jack splitter. Plug the splitter into the DAB radio and the FM transmitter into one oulet on the splitter. Plug the headphones into the other outlet on the splitter. if it works then the headphones will act as the aerial again.

A slightly more expensive solution might be the Pure Highway. Portable DAb receiver with built in FM transmitter.

I tried this the other day, pluged the spliter in then pluged a 2m headphone extention cable into that, great so far, I was getting a full strength signal. As soon as I pluged the FM transmitter in the signal died.
Tried it with one of those cassete connectors and it works great, but for some strange reason the transmiter kill the DAB signal.

I don't see that it's all that strange; you are basically transmitting an FM signal straight into the DAB receiver through the headphone cable and probably overloading it.

right now peeps, i've had a sensible look at your posts and had a costwise thought about it.

1. buy a revo/new radio altogether - would love to, but the minimum wage just about covers the cost of runnin the car so thats out the question

2. splitter - tryed that and the signal died (as with eeean)

3. tape converter (one of those fake tapes with the wire hangin off) - i tryed this a couple of weeks ago when i first got the car and it didn't work.

But while out and about in the pub the othernite (i was on coke before i get the drink-drive speech) my work collegue (he looks like dexter from dexters lab) advised me to take the tape converter and put a knot in the wire about half way, so i did it and i now only get a signal error of about 20 (rough average). he also advised it might make a stronger signal if i put the radio on its side (headphone socket facing upwards) in the glove box - might try that one later.

thanks for the advice peeps

Kenny
