>From reading your post, what I'm getting is that the Icom is keying the VXR5000 okay. When the VXR5000 receives the responding radio that it isn'y keying the ICOM. If that is right, ....you also need a similar circuit from the COS circuit in the VXR5000 to key the ICOM. .....NEVER CONNECT ONE TYPE OF RADIO TO ANOTHER WITH OUT SOME KIND OF BUFFERING CIRCUIT like the transistor switch that you have built, with out completely understand both circuits. after you let the smoke out it is too late to say AAAAAAAAAAAHHHHHHHHHHHH CRAP!!!!
