In my case L.O. is not 125 Mhz , it is 200Mhz

# Ham It Up / Up convertion
When using an upconverter it's common to use an offset to access the correct frequency. As an example, if you want to use a HamItUp which is designed to listen from 60KHz to 30MHz, you'll need to tune your portapack to 125 MHz + the frequency you need.
When using an upconverter it's common to use an offset to access the correct frequency. As an example, if you want to use a HamItUp which is designed to listen from 60KHz to 30MHz, you'll need to tune your portapack to 125 MHz (or any otherfrequency used in the upconverter local oscillator) + the frequency you need.
Doing the calculation and tuning while adding the frequencies can be a bit tedious. Don't worry: just got into your portapack's settings, Radio menu, and set the shifting you need.
