High Power 2.5 Watt Transmitter Kit FMTX1
$69
This kit uses a single transistor to provide up to 2.5 watts into a 50-ohm load. It can be set on the FM band from 88-108MHz.
Audio is 500mV P-P with Australian pre-emphasis. Power supply from 12-24 volts DC. Range up to 100 miles. Leaky coax
distribution can be used with any of our transmitters, terminate up to 2km of coax with a 50-ohm resistor and no radiation
occurs. Use a 150-ohm WW pot and you can set the level of radiation up to 300 metres from the coax. You can use this
method to comply with DOTC schedule 3.
