AV681TX-Kit, Rev B Page 1 © Nov-03-2008 AV681TX 5.8GHZ A/V TRANSMITTER KIT Rev-B Hardware INTRODUCTION This 5.8Ghz 100mW A/V transmitter kit provides a custom printed circuit board set and quality electronic components. All you need to add is an antenna of your choice and about three hours of your time. NOTICE: This kit involves precision SMD soldering and it is NOT intended for beginners to assemble. It is suitable for amateur radio hobbyists and RF technicians. The builder must have good quality soldering tools, an anti-static work environment, and electronic assembly experience. Note: This transmitter will require a ham radio license for hobby applications. Some countries may prohibit use. Please consult your government’s spectrum regulations before using this device.
