[amsat-bb] 9.6k woes and FoxTelem

[Frank]

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.

>>> 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...
