Ted, Over on the yahoo Marconi group a thread on the fly back was hashed about. It was told that some less in demand models of test gear use the same parts. You might want to hop over there and see if the part can be crossed over. -Kevin _ From: Repeater-Builder@yahoogroups.com

Another point regarding line voltage issues, the distance from the substation or distribution system voltage regulators to the load may determine what you may see at the wall plug. Typically homes located closer to the substation (or regulator bank) will see higher voltages than those further a

RE: [Repeater-Builder] OT Power Factor

Your typical home meter measures only real power consumed. There is no such thing as "reactive power being delivered to you". Any reactive power that you may be concerned with will originate on your side of the meter at the load. You really don't care about it there either as long as the extra

Nicely said Nate! Other benefits include MUCH longer battery life (how long does your cell phone last? 4 hours? 6? A pager that doesn't last at least a month on 1 AA cell has a problem!) The lack of a transmit function is necessary in many environments, like hospitals, as well as many hazardous
