Near LO's and S band for $6

Think of it like this.  In order to suppress the unwanted image at 2400 
- 20 you need an
unrelizable for realistic prices filter to pick off the unwanted image 
out of the mixer.

Scale it down to 75 meters.

This would be the same as use a traditional filter based conversion 
receiver  to listen to
4.00 Mhz and having the LO for the 33 Khz IF be at 4.0333333 Mhz.   It 
is terrifically
hard to make analog direct conversion receivers work well and this is 
the near equivalent.
