This oscillator generates frequencies 5.135 – 5.865 MHz. Recommended IF is 8.865 MHz or 9 MHZ, then TRX will work on 20-meter band (14 MHz).
Features:
- High stability;
- Frequency range – 5.130 – 5.870 MHz;
- Output voltage - 0.25 – 0.3V; (if need more, needs to use VFO amplifier)
- A buffer stage, which ensures good isolation between the oscillator and the load;
- RIT function
- Possibility to use auto-tuning frequency (allow to keep and auto-tune the frequency in case of its running)
- 12V DC.
- PCB dimensions 100х50х50 mm.
P.S. IF change value of winding you may get any frequency! For example, we have tested to get 3,5-4.0MHZ and 7,0 MHZ. So, it could be used as VFO in direct conversion Receivers/Transceivers.
