I'd work at pinning it down more specifically using portable gear before making enemies. I've never heard a computer in those ranges, but I sure have heard the network on 147.00. Your problem *might*

It's a very simple system. So simple they needed an extra port in which to run the DC supply. The two control heads are just aluminum boxes with two rotary switches that provide power to the relays o

I'd need to see more of what's inside and the specs. Any commercial supply should have both ripple and noise specs and in 0.1 or 0.10% although those particular figures would be *very good* Unfortuna
