I think to use 550mhz in case of 360 mhz IF.
So image will be around 190 mhz, but here also there are very strong TV and
trank radios.

BTW,
Are you using upper or lower image ?
Let's say bringing 900 to 400 you can use LO of 1.3 GHz or of 500 MHz
right ?
With 1.3 GHz you will get images from 1.7 GHz
With 500 MHz you will get images from 100 MHz (FM Radio !!!)
Cheers,
