Hi there List, With too much free time in my hands, I was really curious to find out what is the actual pre-selection RX bandwidth for each main band: HF, VHF and UHF. After identifying the filters, I put the circuits in LTSpice and ran the simulation. The results are in the below pictures. I got intrigued on why the UHF band was extended that long. For completeness, the dotted line depicts the signal phase. 73s de PY2RAF! o/
