Does this software display the RDS phase (relative to the 19kHz pilot)? If so I am interested in purchasing it. I need to set RDS phase on several radio stations. My current method is to use an o’ scope at the composite output of a broadcast processor. The problem is that this must be measured without audio present to see only the pilot and the RDS signal on the scope at the same time. That means that I have to take each processor off air to measure and set RDS phase. This can be a problem and is always an inconvenience. Also one gets different RDS phase readings between different models of audio processor because of differences in the timing of the pilot reference signal that is supplied to the RDS generator. So anytime I change to a back-up processor I have to set the RDS phase on the RDS generator again. I have an RDS monitor and several modulation monitors but none of them will display RDS phase.
It doesn’t, but that’s a good idea for an upgrade. Thanks for the idea. Definitely could always use some more statistics.
That being said, in any testing I’ve seen… the tuner doesn’t rely on the pilot at all for RDS, which is why RDS still works when doing things like AutoPilot… Leif’s true-mono detection that fades out the pilot, for noise reduction purposes. 🙂 I’m not sure if that was part of the testing of the Omnia.9 @ NPR Labs, but I would guess it was, since it’s always on, and they would have noticed. Hehehe.

Audemat, the manufacturer of our 5 RDS generators, explains a procedure to adjust the RDS phase in the absence of a scope by monitoring the RDS data error rate on the fringe of the coverage area and adjusting the RDS phase for the lowest error rate. So the RDS may work in the absence of a 19 kHz pilot but I don’t expect it will work as good as it would with the pilot up and in phase.
I haven’t read about Leif’s AutoPilot. It sounds interesting. I’d certainly like to learn more. Do you have any links?

They’re portable…work best (obviously) when connected directly to a tap off the transmission line to minimize error resulting from multipath.
MPX Tool is amazing, Microgren is more expensive and gives a much deeper look at everything: l-r…longterm average carrier deviation…rds…rds errors, for an upgrade, it’ll even read crap HD, too.
