Simple Transmitter (TST)



Specifications
  • Power Output: ~4w into a 50 ohm load at 12v
  • TX power amplifier efficiency: ~70%. Finals stays cooler, transmitter draws less power. Note: TX designed for CW type transmit duty cycle. Prolonged key down operation is not advised.
  • TX harmonic output suppression readily exceeds FCC specifications: >55 dB attenuation typical
  • Spot Switch: Turns on the oscillator and buffer so that you can find it with a receiver
  • Built In Keyer: Keyer chip included with adjustable cw speed pot
  • Straight Key mode: Power up with the jack “ring” shorted (mono plug) causes the keyer to enter
  • straight key mode. This mode is useful with external memory keyers for beacon use, as well as normal straight keys or bugs.
  • Straight Key “dotting” mode: Staying key down for several seconds places the transmitter into “dotting” to protect the finals.
  • Built in receiver T/R switch with “mute” output: An external receiver can be hooked up directly to the transmitter “RX” output. “Mute” output provides an open collector shunt to ground during transmit.
