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 FM transmitter pcb with all components mounted. We have decided to expand the transmitter frequency to include the Japanese FM Band, so it is now possible to tune the transmitter from 76,0 MHz to 108,0MHz, although you may have to squeeze or drag the transmitter coil if the transmitter won't lock the PLL. You tune the transmitter with the four jog wheels in increments of 50KHz. (EG 0, 2, 0, 5 = 102,05MHz), note that a frequency change require a power down of the transmitter.
