The range 1..30 MHz;
Auto-hold of VFO function (+-20/40Hz)*
The maximum resolution of the measured frequency is 10 Hz;
Input sensitivity 250 mV;
Supply voltage 9 ... 12 V;
Current consumption 5 mA.
Holding accuracy of VFO- + -40 Hz or + -20 Hz.
The device has memory with 5 Offset (+Offeset, -Offset, direct measure)
*This options works with VFO which has varicaps. Frequency meter control the voltage on varicaps and hold the frequency, that make VFO quite stable.
