I’m pulling out what little hair I have left. I have borrowed a friend’s IC-910, and want to feed the output of the radio to both a signalink USB and also to the direct Line-in of the laptop to receive the 9600 bps signal off of the 9600 pin 4 of the Data mini DIN. So here is what I did:
First, I took a cable that was straight through all 6 pins and added a RJ-45 connector on the end, in such a way that pin 1 of the mini DIN was pin 1 of the RJ45 connector, pin 2 was pin 2, ... pin 6 to pin 6, etc...
I created a patch panel with two patches, one that is straight through, and one that crosses pins 4 and 5. More about that in a bit.
The signalink was wired in such a way that it is expecting the input on pin 5, and ground on pin 2. So in this case when I connect up the cable to the signalink with a straight through cat 5e cable, it gets the audio out of the rig at 1200 bps (pin 5).
When I want to use the 9600 bps out, I unplug the cable from the patch panel and connect it up to the other patch, where it takes pin 4 (9600 bps) and throws it on pin 5 of the patch panel output. I then have a cable that takes pin 5 and brings it to the tip of a TS 3.5mm mono cable. Pin 2 (GND) goes to the sleeve. I then plug this into the mic input of an older Apple MacBook Pro.
I remembered to set the IC-910 to 9600 mode. I start FoxTelem and set the input to the Mac’s wired mic input, but I never decode anything.
One thing that is odd to me is that when I toggle the 9600 mode on the IC-910, I do not see / hear a difference. I would imagine it should toggle some signal on and off the pin 4.
Any ideas would be highly appreciated. I have also just tried a simple cable with pin 4 to the tip and pin 2 to the sleeve, and have seen similar results.
I appreciate any ideas, criticism, etc...

Kevin,
Have you played with the input levels on the sound card?

If you listen to a local repeater does the audio flow through fine to FoxTelem? Can you hear it?
Show us a screen shot of the display when it is trying to decode. If the bits do not look like a square wave then the signal is being filtered somewhere in the chain.

Yes, the levels are maxed out. I also hooked up an oscilloscope to verify the signals presence on the line. -Kevin (KK4YEL)

I have a IC-9100. In addition to setting the menu item to 9600 baud, the radio has to be in FM digital. To put the IC-9100 into FM digital the FM mode button is de[pressed until the “D” icon shows on the display. This disables the filtering to allow the DUV audio from the satellite to pass onto the sound card. I don’t have an IC-910 so don’t know if this applies to that radio.
I am using the IC-9100 into a computer sound card and Foxtelem and decoding the data and uploading to the server.

Frank, I have read through the manual and it doesn’t appear the IC-910 has a button to long press to put it in digital mode. Also, I learned that the 9600 mode is only a toggle for the TX. On RX, it doesn’t change the signal getting on pin 4 or not. The audio is always on pin 4. -Kevin

Kevin,
To preserve your sanity you can measure the frequency response of the radio and see what it is doing to the audio path. Feed the audio into the sound card and run a sound card spectrum analysis program. There are many, such as Sectragram. There are several listed here: http://www.radio.imradioha.org/pc_based_test_gear.htm
To do this just tune to a part of the band with pure noise (which is most of the band). The response you get then just shows what the filter is letting through.
There is an example spectrum in the FoxTelem manual on page 13. This is marginal. Ideally it extends closer to zero Hz. http://amsat.us/FoxTelem/foxtelem_manual.pdf

Apparently, things are working just fine. Not sure what changed, other than being patient. Maybe I just can't decode DUV on AO-85 which is what I doing all of my tests on. I left it running with all of the birds today. Swung home for lunch, and got a great surprise - managed to help with the AO-92 photo... Thanks to everyone who gave me encouragement and suggestions. -Kevin
