Here's a teaser screen shot of what I've been working on.
I'm not happy with the bit synchronization in the decoder function, so
I'm not releasing this yet. But here's a screenshot.
(And no, I'm not a fan of Country, but that station has a strong RDS
signal, so it lets me do more testing :-) ).
The other station on the *same* tower has a signal that's about 12dB
lower, and the RDS carrier is quite weak--according to the
registration data, they're both putting out 100kW, but the weaker
station is 100ft lower on the tower. Propagation, how it work? :-) :-)
Both stations I use are just over 100km away from me, and I'm using a TVRX2.
