Sounds to me like Ryan was asking whether this discussion somehow applies to the transmit LPF's. And that Farhan is thinking only about receive.

Ryan,
You could do it with two tunable filters : first covers 3.5 to 7 mhz, the second covers 14 mhz to 30 mhz.
Alternatively, you could try low pass filter to cover 3.5 mhz to 7 mhz. In such a case, you will have to use higher side vfo injection. A problem with the LPF could be that the rf amp would overload with broadcast qrm.
