After building our test stereo FM transmitter with RDS based on the RDVV 300mW, I received mails from several people suggesting why not let the PC to do all the signal processing and use a simple FM transmitter. This surely had to be tried and we have build a single pcb "back to basic" version of the the RDVV 300mW without display.

The RDS stream is generated with a trial version of the very nice program Airomate.
