into my FM transmitter

And how is that supposed to work with a bunch of AM radios?



You feed the headphone jack of the FM radio into an AM XMTR...

Sheesh Jeff!!



Heh, I keep seeing people totally oblivious to the requirement
of an AM transmitter for BCB AM radios.


I was oblivious to your requirement, you made that clear. I just
wanted to let people know what I do, and to make them aware of the old
radio programs available over the internet. Listening to Dragnet as I
write, on an FM radio!

I meant to say,
I wasn't oblivious to your requirement, you made it clear you wanted AM.

Aside from not being AM, I plan to give that link a listen. Sounds like
fun listening to those old radio shows. (By the way, those shows were
probably all broadcast on AM. FM did not exist at that time).

Yes, check into it, there are at least 6 different internet
broadcasts of old radio shows, probably more.

btw, has anyone tried a class E amplifier as an AM transmitter?
Base/gate drive is transmit frequency, B+ is the audio.
I'll google it.

In the western hemisphere...

"On June 8, 1988 a conference held at Rio de Janeiro under the auspices
of the International Telecommunication Union adopted provisions,
effective July 1, 1990, for the countries located in the Americas to
add ten AM band transmitting frequencies, from 1610 to 1700 kHz."
