Yes but i dont understand how i have to wire it to the connector you see on the first post.
There is no other pugs (just an audio output on the back of the radio).
The SCU-17 is really made for high end transceivers made for the amateur bands. The diagrams in the manual are not going to help you much, except for the one that is labeled "Interfacing to Other Transceivers", at the bottom of page 12. All of the SCU-17 features can't be used, but some can.
My interfaces are home made, but I have a HTX-100 that only has a microphone connector on the front and a audio output jack on the back of the radio. I have used for it for RTTY/psk-31 on 10 Meters.
First is the supplied USB cable (Type A male to Type B male). This should connect from the SCU-17 to your computer. When you connect this cable up, your computer should be able to see the "USB Audio Codec", which is the audio interface within the SCU-17. The USB cable also provides power for the SCU-17. You should also see a "Virtual COM" port on the computer. This will be used, in your case, for PTT (Push To Talk).
Then you need to connect the SCU-17 to your radio using the 3.5mm jack on the rear of the SCU-17 that is marked "Audio In/Out". The "Audio Out" (Sleeve and Ground) will go to the Audio Input on your radio. That would be Pin 1 (Audio) and Pin 5 (Ground) on the microphone connector.
Then the "Audio Output" from your radio (3.5mm connector on the rear of the radio) needs to connect to the SCU-17 "Audio In" (Tip and Ground).
The problem is going to be with the PTT (Push To Talk) signal. The microphone for the AE5890 provides a ground for receive, Pin 2 (PTT-RX Contact) to Ground (Pin 5). When you go to transmit, the receive ground, Pin 2 (PTT-RX Contact), is removed and applied to the transmit pin, Pin 3 (PTT-TX Contact). So, when you disconnect the microphone, the receiver may not work, until you ground Pin 2..
You will probably have to use a external relay driven by the SCU-17 PTT signal. The relay could then provide the alternating grounds needed when switching from RX (Pin 2) to TX (Pin 3).
If necessary, I can probably draw you a diagram that will help explain the connections a little better. In the end, this connection is going to take a little experimentation and may not work the first time.
Note, at
Alan Electronics, under the "Amateur Radio" link, is information for converting the AE5890 for Amateur Radio use.
Good luck with your project.
