    pts rule name description ---- ---------------------- -------------------------------------------------- --> AeroElectric-List message posted by: "Gerry Clabots" <gclabots@execpc.com> Recently I have noticed posts referring to an endurance bus, Is this the same as the essential bus? I have Bobs book and I see no mention of an endurance bus. Wondering if these terms referring to the same thing. Thanks Gerry

The term "Endurance bus" being Bob's more recent choice of name. He feels that it more clearly describes it's intended purpose.

    --> AeroElectric-List message posted by: "Dan Checkoway" <dan@rvproject.com> I absolutely love it. So simple to read & use. If anything strays from the norm you hear the auditory warning, look at the screen and in RED it tells you what's wrong in the bottom left corner. Very, very nice stuff. It's easily readable in all light conditions, and in a way ironically it's clearer in direct sunlight. The 2-hour data logging functionality is excellent. You can really visualize what's happening when you dump the data to a file and graph it in Excel or what have you.

Thank you for the kind words. I'm pleased that you found the work so useful. I presume you're referring to the various forms of ukum-yucky that propose to increase the transfer of heat from solid state devices to their mounting surface, usually some kind of heat sink. I haven't used any in a new design for over 20 years. There are heat-transfer, gasket-like materials that can be cut to shape, punched for holes and go on dry. See http://www.bergquistcompany.com for an exemplar product offered by Bergquist It occurs to me that you may be asking about the silcone greases popular for waterproofing. Dow Corning DC-4 has been around for 40+ years. When I was in the 2-way radio business, we would fill the interface of coax connectors on a tower with DC-4 before assembly. It would keep the moisture out of the connector. Did a net-search on the stuff and found several instances where DC-4 was recommended for moisture proofing connectors or aiding in their assembly. Here's a few . . . http://www.ramaircraft.com/Catalog/SB&AD/ramsl200001.htm http://www.lambda-emi.com/product_html/500aresource.htm http://skymate.hosting4less.com/downloadables/SkyMate%20100%20Owners%20Guide-VMS.pdf http://www.amphenolrf.com/products/AssemblyInstructions/hn.pdf http://www.dielectric.com/broadcast/instruction_booklets/IB162-A.pdf I guess I'm not a really big user of DC-4. I think the tube I have was purchased when I was in the radio business . . . about 1963. Itty-bitty amounts go a very long way. My 3 oz tube is still about half full. Bob . . .
