The "monitor" system you are building in a computer case has had my head running ever since I saw it. I want to make something similar. I also want to add a 350 watt computer power supply to it. It should give me about a 30 amp supply. The good part about it, it will also give me a 5volt line, and I am going to pull a 12volt line and make a circuit to make it variable from about 3 volts up. I have about 4 29GTL classics that I am going to use in it. I can make a signal generator with it and put a line in for the 455 signal out of it. I will have a speaker hooked to the 29 so I can hear what ever radio I am working on. I thought about putting a ssb radio in it so I can check ssb. I pulled my old Browning LTD out the other day, but really don't want to "trash" the LTD. Think I will head over to E-Bay and find a cheap 40 channel ssb radio I can put in it. Probably a Realistic as I don't have use for most of their radios...
When I get going on it, I will post some pictures
