Features include:

• Dip switch frequency selection, 5 kHz resolution.
• Exceptional modulation for voice and ctcss.
• Very low noise synthesizer for repeater service.
• Commercial grade tcxo for tight frequency accuracy in wide range of environmental conditions:  2ppm -30 to +60°C.
• In stock for same day shipping.

The T301 VHF FM Exciter is a  tough, commercial-grade, low power transmitter which answers the need for the most demanding applications.  It can be used as a stand-alone unit or as a driver for our class-C power amplifiers.  It is ideal for voice operation in repeaters and voice links.

You can rely on our transmitter and receiver modules for your project.  If you have any questions, send us an email.  We'll be glad to work with you and suggest cost effective solutions.
