    Nice

    How effective is it in real life testing? and which antenna are you using?

    First, sorry for the double post.

    @pierrotm777
    I can only use windows antennas. That's not perfekt. Now i have two antennas and audio out is switching automatically to the receiver with best reception (similar antenna diversity). I hope the reception is now better.

    @ibf
    I will insert the modul in my car end of June. Then I can say more. I have two Blaupunkt DAB Autofun A-D G 01-E antennas.

    OK thanks, will wait for your report. I have seen someone made a dual Silab USB FM tuner a while back but Im not sure what the end result was.

    If the improvement is significant I may go through the trouble doing the same with 2 Verona DAB modules.

    Good luck

    Hi sater, really nice work there. I think this would really work in fringe areas. I'm in one, signals can momentary drop and return over the length of the car as it moves along the road. With an aerial at each end of the vehicle (or as close a practical) I feel this may stop that annoying flutter affect. When I'm under 30klm from the Major city I have perfect reception from my amplified roof top aerial. I live over 45klm from the transmitters and depending on the weather, reception can get quite choppy out here in some parts.

    BTW, I had to modify my DAB SW to AUTO hide slideshow images at night when the dash-light brightness is turned down below a certain level (this also dims the LED backlight in the 8" display via PWM.) Some stations transmit a white background and even with the backlight almost off and auto brightness/contrast driven way down, it was still annoying in dark unlit road conditions

    Hi Mickz, i live in Wiesbaden - Germany. Here are tree transmit antennas in my region. We have small hills and valleys. On my way to work I always dropouts. Currently I use a NOXON DAB Stick. Even with a trip to Berlin I do not have the best reception. Currently I use only one antenna. The Antennas are on the right and left site of the cargo compartment. The original Volvo antennas are in the cargo windows and rear bumper. The FM reception is perfect. I'm very excited.
    I have removed the slideshow images and BBQ in my modified frontend. Images are not supported by my modules (to old :-( ), BBQ is not compatibel with tune the last sender automatically (I have not inserted this in the PIC firmware).

    @pierrotm777
    This is not a problem. But it is necessary that Mickz and JP from MonkeyBoard say that's ok. But I think the compiled dll and PIC firmware is not a problem.

    Mickz,
    I'm trying out your app to add a radio to my Kitchen PC, but I can't seem to find the "Minimize" button and the app overlays my main background (iOS / Android inspired) application, hiding the launch icons.

    What's the odds of adding the functionality when "Window Frame" is On?

    Hi, just had a big operation on my Sinus 4 days ago so I may not be around for about 2 weeks or so (wish I was dead at the moment)

    Made a quick mod and uploaded on Page One - Latest EXE File only - DabFmSa1.zip, hope nothing broke and it works.
