Thanks for all the answers. To set the story straight, the reasoning
behind the question was not to determine if I could transmit "hi-fi"
AM, it's simply a matter of cost. At $125 a clip for an AM filter and
the fact that I may only transmit AM once or twice in a lifetime, I
couldn't see the extra cost to add the AM filter if TX through the FM
filter worked.
Since others have already identified that a filter can be "fooled" into
thinking it's a different bandwidth, I do have a plan that I'll try
somewhere down the road. Looking at the schematics it appears to be an
easy solution that I can use an empty filter spot and diode switch (add
two diodes) that position into an FM filter consumed location. That
empty spot would be designated as the AM filter spot.
Yeah, I know, it's only $125, but I'm a cheapskate.
