I've posted some suggestions for powering the SCR-288/BC-474 for display and use at military events and rallies. In addition some minor modifications (reversible) to the GN-45 for use on the set. If anyone has a GN-44 you can send it to me. :-) Z http://k4che.com/BC474power/BC474%20Power.htm http://k4che.com/GN-45/GN-45.htm
