Thanks Hossfly,
I think we may have gotten two different post confused. I gave up on the old Kraft Radios and wrote them off as a bad idea.
Your bold print statement above said that a module from one manufacturer placed into another is cause for
transmitter emission realignment by the manufacturer. I have a Futaba FG Transmitter with an AM module and if I replace the module with another Futaba FM Module designed for that Transmitter does it need realignment? If so then I'm confused again, then why did they have modules to begine with if you cannot change them.
Thanks
Don't mean to confuse things. My post was to "da rock" but then I brought you into it. I also goofed, so see edit in my post above.
"da rock" was so far off base that I just had to bring that to his attention, but did not care to write a book for his benefit.
The MODULES are the transmitting agent. The rest is mechanics to determine what and how transmission takes place. Now out there in the real world, people change transmitter crystals all the time regardless of the written words. Even now when freqs. are checked at some events, and especially on local fields, now and then a supposedly NB transmitter can be found blasting both sides of the spectrum's next channels.
Just proves that nothing is perfect. OTOH, in this day and age, actual equipment problems are very rare. Now the jug-heads using that equipment, well that is another story.
As far as changing modules between suppliers, it is easy to legislate the most retrictive so that is what FCC usually does. Just say "NO". "Cliche:" Never ask anyone a question when that anyone is not qualified to say "Yes."

OTOH, there is little chance of any major differences in the modules of anyone manufacturer.
Of course it is much easier and
less expensive to have one or two small transmitting module/s to snap in place, than to put all that stuff in each transmitter itself.
