Switching ON and OFF of the VBF always interacts with RGO ONE receiver Automatic gain control system (AGC). Since VBF reduces noises in RX path – from the ether and from previous IF amplifier, AGC system will act slightly different.
RGO ONE has a neat option – 4 pole crystal filter which bandwith is controlled via varactor diodes. Firmware generates proper voltage bias and this manner realize 10 fixed filters – 3kHz down to 220Hz. Variable bandwith function is activated
