It uses a doublet circuit to reach the 40/20/15/10 meter bands. Has built in power supply. The rear panel has impedance ports that provide up to 20V RMS output at 50 or 50K ohms. VFO is very stable after a 20 minute warm up.
There is a Send/Standby function that can be controlled by transmitter PTT or manually at the VFO. This provides adequate drive for most transmitters. I used this VFO on many applications requiring a 3.5-4.0 MHz fundamental oscillator frequency.
