thanks! i’m already seeing both why people have a problem with the am-25 and why people enjoy it.it seems to have some pretty bad problems out of the box, but it also seems like a transmitter that is very open to experimentation and modification.
i am having pretty bad audio distortion problems. i have to turn the audio input way down. the degree i have to turn down the input depenends on the audio i am inputing. this makes me think a compressor would help a lot.
what do you think of the modulator modifications shown here: http://teslapress.com/am25.html
the article recommends replacing the TIP310 (Q9) with a 2N3055. have you tried that?
