Hi All,

I want to be able to pick off COS/COR from an Icom 2100. I found this page which says it can be found on J2, pin 1.

https://translate.google.com/translate?hl=en&sl=id&u=http://yc5nbx.blogspot.com/2008/12/icom-ic-2100h-cos-pin-out.html&prev=search

It says you need tone squelch enabled. Whether I have TSQ enabled or not, when I key up a radio all I get from J2, pin 1 is a brief low pulse and then a brief high pulse when I un-key. I could do something to catch the low pulse but is there somewhere to tap into either a solid high or low when the radio is receiving a carrier? I have probed J1 and J2 to no avail. It would make interfacing it MUCH simpler.

Thanks!

Edit: How embarrassing. Due to operator error, I see that in actuality J2 pin 1 is high with no signal and goes low when receiving a signal. That should work fine. Never mind...
