High level Amplitude Modulated 430MHz video transmitter for the 70cm Amateur band, built on a 71x100mm PC board. The design uses a sync stretcher and high level modulation to overcome the linearity requirements when transmitting TV signals, and produces up to 100mW, ( +20dBm ) output. For Audio the optional 5.5MHz EME158 Audio sub-carrier Kit can be used.
