Hi Kevin, Yes I did remove the transistor and go directly to the controller from pin 8 and this seems to work ok. I am going to have to order a new plug and pins for the controller since moving the controller around caused the wires to break off in the connector. I guess I should move this to the ICS group since most of the other stuff I have deals with the Controller. I was aware of the mods that you suggested and while some like the squelch I like there are a few that i prefer not to do. If you on the ICS group then maybe I will see you over there. Again Thanks Steve
