The EME153 is a high performance 2.4GHz FM Video Television transmitter has a tuning range of around 2300 to 2600MHz, and is ideal for ATV. The design has an onboard Video Amplifier and Pre-emphasis, and uses an ERA MMIC as a buffer amplifier to give up to +5dBm output. An optional Phase Locked Loop Kit and Audio Sub carrier Kits are also available to built a complete FM ATV transmitter. The Kit is easy to construct and align, and a surplus FM Analogue Satellite receiver and 2.4GHz downconverter can be used for viewing the signal.

1/ There is a fault with the EME153-Rev1 PC boards. A wire link is needed on the 50kohm Trim-pot between the wiper and the pad that goes to pin 2 of IC1. The fault is that the video deviation cannot be adjusted.

The construction is quite straight forward and many of the components are easily fitted with tweezers. The Kit construction notes and overlay diagrams should be carefully followed when constructing. For larger pictures to check orientation of some components click the images below. Remember to fit the wire link to the deviation trim-pot under the board. BUY THIS PRODUCT
