The mk1 and mk2's RDS data separation is performed in the DSP (onboard the empeg) - the mk2 tuner feeds FM MPX data into the main box.

Hence, the RDS stack is the same on both. There have been improvements with the 1.1 tuner, but I can't promise that auto-tuning will be spectacularly good on the mk1 due to hardware limitations (tuner settle time, noise on the signal strength line). Currently, 1.1 does not do auto tuning, but this is going to be added, along with TP/TA support.

We will try to make the mk1 as fully featured as possible in this department - TP/TA whilst listening to MP3s should be very possible, as we can retune & play with the tuner without disturbing the audio. The mk2's tuner is better at this though.

There have been improvements to the tuner in the last year (the late betas before 1.0 had many improvements) but 1.1 has a lot more stuff in that area. John's been working hard :)
