Since the actual DSP is done in the PC, RX bandwidths less than 25 Hz are possible. When I quoted 33 MHz to 1 kHz bandwidth I was stating the I/Q data rate to the PC (similar to soundcard sampling rate). The encode clock (whether 67 MHz or 133 MHz) is decimated to a much lower rate within the on board FPGA and/or AD6620 DDC co-processors. This rate can be as low as 1 kHz (or less) to the PC.
