Well, I dont know much about a lot of the heath monitors, but I have an
sb610, and in the manual, it gives several (I think three) IF
frequencies to built for. Different coils and caps. I remember it had
options for 455 and something around 3 Mhz. Years ago, I set it up using
my own kludge for an If that it didnt have the docs for. I undid my
modification when I got rid of the tranceiver that needed it. I have the
manual, and can dig it up to get more exact data, but it *definitely*
has an IF input to display the recieved IF signal. This sb610 is the
only heath monitor that I've ever owned or had any experience with.
