Simple Transmitter (TST)
- 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.
