Stereo Tool

Nothing here guys,just black magic,hocus pocus. the Omnia video was not scientific.It should have been a A/B comparison all on the same ride, not done one day and then the next.DUH? Just Omnia trying to sell a processor..

Yup! But the fact remains that we do not see this everyday

The newest FM receiver chips can't handle SSB anymore, they use tricks to reduce multipath (!) which cannot be used together with SSB. I visited the manufacturer yesterday and we've tested it. So I would hereby declare SSB to be dead...... Only the version that starts SSB at about 12 kHz ("Probably optimal" mode in Stereo Tool) was kinda ok.

Hi Hans what I want to ask real quick is am Asymmetrical DSB Filtering. So more bandwidth can be used in a stereo transmission.

You mean to protect the RDS signal and still be able to go above 16 kHz?

1. Most people won't notice it at all
2. Most radio's will filter out these frequencies (if they didn't you would hear the RDS signal as well)
3. Many radio's including the latest generation car radio's can't handle it and will switch (at least partially) to mono even if reception is perfect.

So.... not a good idea.

You could try it out using one of the SSB modes and a higher maximum frequency if you want.

That is what i am doing right now. SSB steep mode and higher filter...

And do you hear more highs with that on any receiver?

70% no difference
20% yes there is a difference
10% not a difference from 14khz and above (bad/low freq filtering)
