IRRC - This is a standard mod with info on the www.va3cr.net site. Only a few easy to find parts, but a bit of work to disassemble to get to the right places. There is a step by step with pictures for those of us - like me - who need all the help they can get! I have a downloaded PDF I can send to anyone who can't find it otherwise. 73, George VE3YV / K8HI
