Do the dongles from RTL-SDR not work?
They seem to support FM and RDS as well?

Assume the issue with these is the PI has to do all the work?

The Sundtek devices appear to be back in stock..
Not sure if anyone has received one yet to confirm if you can save station lists and RDS etc works.

Hello there,

I'm using the following board for a very long time now, it's a bit pricey but its reception in DAB and FM is very good (quite superior to siXXXX and SDR-RTL in my hands). I'm not affiliated at all with anyone :-)

I purchased 2 there:
https://www.cartft.com/catalog/il/1618

It is based on a Keystone T2_L4A_8650C DAB+/FM module.

Control and power is through USB, and audio through a 3.5mm jack (so no conflict with HifiBerry - although I'm using a Dragonfly on USB), but for 6 months I'm using the I2S directly on a Pi 3 GPIO with excellent results:

It would be great if they could make a Pi Hat of it: that could reduce their cogs and make it smaller :-)

but I strongly recommend it.

Cheers

@Elvis thanks for the idea, but price almost 100 Euro... hmm it is a lot for DAB/FM receiver. Recently, we have made survey, and asked about price. The result was that users expect something cheap around 20-30 dollars, max 50$. In 100 Euro/piece you can develop exactly what we need. On the other hand we have calculated cost for our prototype and we know how it looks like with the price...

Nevertheless, in few days we will try to collect and sum-up all ideas here. Then we should get overview, and hopefully some good solution.
