FM test mono transmitter
Description:
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.

Zoom in on the homemade 4,5 winding inductor, with outlet after 1 winding. Make sure the inductor is as uniform as possible, otherwise the transmitter can get problems tuning properly.
