HPF/LPF Filters and switching in ANAN Transceiver

The ANAN-200D has a very effective set of High Pass Filters [HPF] and Low Pass Filters [LPF], available
on the Setup, General, Ant/Filters/HPF/LPF tab. The HPF and LPF are automatically selected as you
change bands, according to the settings on this form.
The ByPass check box on the left side of the HPF/LPF tab, when checked, removes the selected high
pass filter from the receive path.
The values in the up/down boxes control the frequency ranges when these filters are automatically
selected.
The 6m BPF/LNA bypass check mark controls the 6 meter low noise amplifier and filtering.
The ByPass/55mhz HPF check mark, when enabled bypasses all high pass filters.
The active buttons displayed between the HPF and LPF show which filters are currently active.
The Auto/Manual radio buttons should be left in Auto mode for most operations. Selecting manual will
allow you to see what receive filters are selected when you bypass or change receiver frequency ranges
etc.
