I have used the site in the past on numerous occasions and have found a wealth of information to solve problems, answer questions, and in some instances, just general knowledge enhancement. Keep up the good work! It is so much appreciated!!

Glen Matejcek ________________________________ Message 3 _____________________________________ Time: 04:43:05 AM PST US From: "ROGER & JEAN CURTIS" Subject: AeroElectric-List: Red Dot SWR Meter Bob, During a previous discussion on this forum, we were kicking around the relative use and accuracy of the small Red Dot SWR meter. You purchased one and performed some comparison tests with your lab equipment. I purchased this unit from you, at a good price, I might add, and will be using it shortly to test the built in antennas in my nearly completed wooden airplane. Have you published the results of your testing of this meter with your reference? It would be interesting to note the actual tested accuracy of this device. Thanks, Roger ________________________________ Message 4 _____________________________________ Time: 05:44:10 AM PST US From: "Robert L.

Good question. There are descriptions of the process at: http://tinyurl.com/7odr8ay http://tinyurl.com/7sn63nx Others have wondered about the conductivity of the process . . . http://tinyurl.com/83qsqhe http://tinyurl.com/74f759b here's an excerpt from a book where the relative conductivity of surface coatings are being examined for use on antenna reflectors . . . though I'm not sure if there's a direct correlation between effectiveness as a reflector and conductor of DC http://tinyurl.com/83pnyn7 This page speaks to the use of chromate coatings thusly: http://tinyurl.com/7n3rx7n Based on the product series, Buckeye uses the following undercoats to protect your investment: [] Alodine: Yellow and Clear. Primary functions are for paint adherence, rust inhibiting, and conductivity. Anodize: Clear and Blue. Primary functions are for cosmetic appearance, hardness, and rust inhibiting. Zinc Chromate: Yellow, Clear, and Black. Primary functions are for conductivity and rust inhibiting Don't have time to delve into it deeply right now but I'll invite interested individuals to Google "chromate" and "conductivity" for some sense of magnitude of conductivity effects on bare metals. I used to know some folks in the Process Lab at HBC. If they're still there, I might be able to get a 'numbers' dump on the topic.

I did a mini-review here on the List when the unit I ordered arrived. I don't recall the exact details but I was favorably impressed with its performance as compared to the Bird and Measurements Corp instruments I have here. Nothing real quantitative. I recall that there were differences at some frequencies and power levels on the order of 10% . . . but in the field of RF power measurement tolerances of plus or minus 10% is pretty good. I'm still hoping that I have a chance to participate in some activities that will take me back inside the walls of NIAR at WSU. If this happens, I think I can get access to the EMC labs for a quick looksee at the HID lamp assemblies on my bench for conducted and radiated emissions. If those programs spool up, I'll pick up another Red Dot to evaluate over a wider range of frequencies and power levels than I can generate here. Given the instruments compact size and relative robustness of enclosure and inspection of the interior, I think the Red Dot SWR meter is a great value.

I have a King radio (KLX-135A) which shows a contactor extraction tool Part No 047-05099-0001, which looks like a straight forward thin screw driver type tool. Rather than try to find one to buy, can anyone post the dimensions so I can make one?
