Having just listened a bit to some AM on my TR-4, ?and having read Mike's comment, I'll point out that the manual indicates that you can receive AM in the X-AM function switch position. ? I have a Push-to-talk Shure 444 in the mic plug. ? I think that is the difference in the procedure.
?
If you don't have a key in the key receptacle, and you don't have a mic with an open PTT switch, then switching to X-AM will trigger the the transmit function and mute the receiver.?
?
The last sentence in the instruction manual regarding AM transmission indicates that if you want to receive AM using the product detector, you need to switch the function switch back to SSB. ?Also the manual states that in X-AM a diode detector is in use in that made for receiving.?
