Crystal Filter Bypass Network Configuration

The Crystal Filter Bypass Network Configuration shown in Figure 3-94 can be constructed using the parts listed in Iable 3-8 and Table 3-9. Table 3-8 list the parts required for the construction of 21.4 MHz

IF crystal-filter bypass networks used with the A4A4 and A4A8 assemblies. Two 21.4 MHz bypass networks are required. Table 3-9 list the parts required for the construction of 3 MHz IF crystal-filter bypass networks used with the A4A7 assembly. Four 3 MHz bypass networks are required.
