Title: ICOM 706 MKIIG Data jack AF out
Post by: WB5OVQ on November 16, 2007, 04:26:18 AM
The ICOM manual shows pin 5 of the data socket (6pin minidin) to be AF out. Also the AF out should be on Pin 3 of the MIC jack. I have no AF out on either pin. Has anyone been down this road? I can't imagine why both pins are not showing any AF out. I am trying to get audio to a TNC (SignalLink, by Tigertronics) to no avail. Please help. Thanks, WB5OVQ.

I don't know for sure on the 706 but the other ICOM Transcievers I have delt with the output on the data jack and the audio is only 200 Mv that may be it if you try and drive some things there is not enough drive
to hear it there try the headphone jack that is what I had to do on the SigLink.

The output on the data jack is very low level (200mV) and fixed (not adjusted by the volume control). Its also 10K impedance as I recall. If you put an 8-ohm load across it the output will drop much lower.

A great big thank you to KF4VKD and AA4PB. I hooked it up to the TNC and it works great. Technology is amazing, but hams are even more amazing. I really appreciate your help.
Thanks again, John, WB5OVQ
