Uh huh. Duh.. I guess you're right.
You know, we were having a friendly discussion about the voltwatch, some of us use them, some don't. That's a choice. What we don't need is someone coming in here telling us about degrees in electrical engineering and implying to how stuipid we are for using such a device that works.
Check back in the posts. No one is saying that it is to replace the voltmeter... expanded scale voltmeter... for measuring receiver or transmitter battery voltage.
You are entitled to your opinion. I, for one, and judging from comments here in this string, and in other strings, and from people that have a lot more experience than I do, know that they work as intended, regardless of any doubts about the performance of the National Semiconductor products used in the device.
If you don't like it, don't buy it. Pretty simple? Even an admiral knows that. And I won't even attempt to compare my education or experience to yours.
What a country!!
