Default Re: 'Proper' DAB conversion for valve radios

Indeed. Of course it ultimately needs to work. However, I am not surprised there are teething problems given that I am apparently the 1st customer in the UK.

I don't have any spectrum analyzer to hand, so it is difficult to know exactly how much DAB signal there is at home. Being digital of course, it either works or doesn't. My DAB radio indicates good strength, but that doesn't necessarily mean much.

I do think the issue is losses in the isolation transformer, and am just waiting for Herbert to get back to me after my most recent tests. Perhaps a proper outdoor, frequency matched DAB aerial would have worked straight away, but being used to telescopic aerials on portables, a wire aerial would be most convenient.
