Astra 19 Radio Stations

hi i have just set up a fta box on astra 19 primarly for the german radio stations but i have noticed if i listen to it through my headphones it has that really bad internet quality stream bubbly sound could a better lnb, cable etc improve this, i am using a 65cm sky dish with a good signal on 19 and the box is linked through rca into my stereo, any help would be great thanks

Unlikely.

LNB & cable will have no effect.

65cm may be too small for some stations and you may have a high BER. Can you check the QUALITY (not signal level which is fairly meaningless) on the Bubbly channels?

Berlin Jazz and Dutch pop Stations sound fine here.

my signal quality is 77% which i reckon is more then ok but perhaps im wrong its jus mainly when i listen with headphones that i can hear it, my box is telling me 100% but i know thats rubbish the meter tells me 77%

Maybe it's just that they're heavily compressed? They might be broadcasting at 'good enough' quality?

Are all radio channels as bad or just some?

If you give some examples, we could compare.

jus goin off topic here a bit the box i have is old and very slow on channel change was thinking of upgrading to a technomate 5200d and an external harddrive for recording my fav radio stations would this be a good system, my current is a manhatten starlight5800

Each station will have a different Quality reading.

You have a professional meter that measures BER, not just Signal Level?

100% quality on all stations is not possible on 65cm dish from 19.2E in Ireland. I doubt many even 77% Quality.

Once a digital signal has reached a certain threshold, any further increases in signal strength will make no improvement to the quality of video or audio.

The problem is not at your end, but at the broadcasters end. Some of the stations are transmitted at lower bitrates. Fun radio and Contact Fm are on the same transponder, so the reception signal strength/quality is the same, but they are transmitted at different bitrates , nominally 192 kbps vs 128kbps.

128k MP1 stereo = terrible, same as DAB 128k, not MP3 128K
256k = great
192k = bearable
