These appear to be nearly identical. According to the forward in R3403C it is a later edition of MCRP 6-22D. Both have an error on page 11. In the chart showing surface conductivity the first two are reversed, that is, sea water should be marked "excellent" and fresh water "very good" not the other way as shown. Sea water is considered to be as close to a "perfect" ground as exists in nature. This error, and the fact that is was carried over into a later edition, suggest that the book was not proof read adequately and there may be other errors, perhaps less obvious. I wonder if any errata were ever published and if so if they are on line anywhere. -- -- Richard Knoppow Los Angeles WB6KBL |

The appalling junk coming out of China should be proof enough of this. Cheap but no bargain! Having said that this little book is mostly pretty good. My RF test equipment preference was HP until around the time they changed to Agilent. Now you can always buy more performance for the dollar from someone else like Tektronix or Anritsu/Wiltron. You also get better technical support from any other equipment vendor than Agilent. The Agilent web site is even a nightmare to navigate. But what really ****es me off about Agilent is the only communication I get from them is what can I buy now? I never get how is the equipment working for me or what features would I want in the future. I don't get notices about firmware/software updates from them either. Basically I have to navigate their obtuse web site to find out about equipment issues, workarounds or updates. -- Telamon Ventura, California |
