Well Kevin, You've started it all again. It's nice to see I'm not the only one with a problem. I'm glad that GE NEVER made an exciter board with a problem It too might get flamed. Some on this group don't know how to take a joke or fix serious problems. The problem with the Spectrum repeaters is that the designer( not engineer or design engineer)that designed the exciters designed things that looks like a CB'r designed it. After a very close inspection and some time spent thinking about the spectrum that I have I found a simple solution to the Tx problems that It has. Here are some serious suggestions. 1 remove the exciter board and replace it with the MASTRII exciter board. That'll fix that problem real fast. The only thing that you need to do is arrange for the necessary +10 Volts to operate it, even the least technical ham should be able to take care of that. As for the controller the SCR1000 has a controler connector on the back for a controller. All of the lines that you need should appear there if the 4000 also has the connector. 73 and good luck with your project. AC0Y Coy
