menu "custom settings and calibration".
In the new firmware version through the menu user can change the following settings:
- the value of IF (+IF, -If, IF=0):
- change the frequency reference generator or power down the output CLK1
- Accurate calibration of the synthesizer
- Self-adjustment of the start-up frequency when you turn on the synthesizer
Synthesizer can be used as a local oscillator (VFO) and reference generator (BFO) in the Amateur radio receiving and transmitting structures with a single frequency conversion, and as a local oscillator (VFO) in the construction of direct frequency conversion
Encoder is included!
