This local frequency and dual-tone generator designed and developed for easy adjustment of Amateur radio equipment (Receivers/Transceivers).
The device’s core is a microcontroller ATTiny2313 which generating a signal by direct digital synthesis method. Also, there are encoder with “Step” button, one more button “Mode” and high-quality liquid crystal display. Based on the compact size of the product and low consumption– its applicability in everyday life Amateur radio knows no bounds!
Frequency range: 10Hz – 20kHz.
• Rotary encoder tuning
• Selectable tuning steps: 10Hz or 100Hz
Output RF voltage: 0 – 2.5 V (regulates by variable resistor)
The calculated harmonic distortion:
- up to 5 kHz – 0.5%,
- above 5 kHz – no more than 5%
Working modes and output waveforms:
- Sine wave,
- Sawtooth wave,
- Dual tone mode,
- Square wave
We offer 2 options:
1. KIT for assembly (includes all elements for assembly + english manual)
2. Assembled unit (includes assembled PCB + encoder + varibale resistor + user's manual)
