Working voltage 14 - 18 VDC

Current drawn 2.5 - 3.5 A

Output power 15 - 18 W

Operating frequency: 80 - 110 MHZ

CONNECTIONS

The connections to and from the circuit are few and simple to do. The power supply is connected across the two points marked (+) and (-) on the board, the AF signal from a mixer or a preamplifier is connected at the two points marked (IN) and the antenna is connected at the point marked (OUT 50 R)

ALIGNMENT

Connect first of all the antenna and then tune into your desired frequency. Adjust all the trimmers in the same order as they appear in the parts list for the best SWR reading in your instruments, while at the same time you get a good output power reading. Repeat the process two or three times to fine tune the transmitter.

WARNING: If the transmitter is operated without having previously connected an antenna to its output stage the latter could be damaged. Make sure before you operate the transmitter that an antenna or a suitable dummy load has been connected across its output and that all the heatsinks have been fitted to the power transistors.
