    Mickz your app works perfectly here but I get no dab stations, only FM. Looks like the Canadian government dropped Dab here mid 2010 and has now opened up the spectrum for HD if any broadcasters want to invest in that after investing in dab before. Oh well, the board is for development anyways. Thanks again Mickz

    Thanks SNO. They implemented it in the higher frequency L band 1452-1492 MHz whereas EU, AU and GB are in VHF Band III (174-230 MHz) anyway it failed for whatever reasons, and thanks again for trying the APP.

    I added response to Send-Keys for an FE or other calling application - Untested!

    Keyboard M - Mute
    Keyboard U - Un-Mute
    Keyboard UP - Previous Preset
    Keyboard Down - Next Preset

    Cheers.

    Hi mate,

    Attached is a schematic for implementing L-band on the DAB development board. You can thank JP from Monkeyboard for this, he's a very good chap. The attached circuit traces off pin 41 of the keystone module. JP also advised that the supplied software will drive it. I do hope you give it a go.

    Hi SNO, that circuit was obtained by mspw, however I assume you are trying it for somewhere other than Canada as they have no DAB on any band from the last info I looked up.

    Sorry mate, didn't realise DAB was a bust in Canada. Probably not worth the effort unless you have a grant with S.E.T.I.

    Thanks guys for your help. Yes I have come to the conclusion that dab is dead in Canada. I bought these units to actually implement into Driveline so that peeps could use Driveline in other parts of the world, as it's geared to mostly NA with the addition of HD and XM radio. Once development starts I am sure there will be a few more questions. Thanks again for your help SNO

    Hi Mickz,

    Just want to say thanks for the source you posted :-) I'm still waiting for my DAB unit (sometime next week) but I'm coding a plugin up for FreeICE. I noticed you save the list to a txt file. Just wondering why this is done as I have just been grabbing the saved list from the dab unit on start up. Unless it's the presets your saving..

    I think it would be good if the dll wrote the last FM and last DAB channel used rather than just the last station played. I might be using an out of date DLL mind. Also on the one I'm using I can't seem to get a stereo indication on the FM side of things.. DAB works fine.

    O.. btw I'm testing my app via VNC to someone who has got a unit :-)

    Great work fella :-) keep it up

    Steve
