Re: [drakelist] Replacement Meters Are Ready
Jim Gerke <[EMAIL PROTECTED]> made an utterance to the drakelist gang -- Thanks for your comment, but the focus of the website is the meters, not the W-4 and WV-4 Wattmeters they are installed in. Seems to me that the meters themselves show up fine. Besides, I'm not a professional photographer. The first several pictures I took were so washed out from the flash that you couldn't read the meter. I was lucky to get the one that's on the website. Perhaps if you told me what detail you're concerned about I could answer your question. 73, Jim K5JG David & Chris Drake wrote: "David & Chris Drake" <[EMAIL PROTECTED]> made an utterance to the drakelist gang -- Jim, you need better pictures.
