OT - Re: [Elecraft] PA cooling
That oil bath is much like the high wattage RF Jammers I used to work on in the Air Force. http://www.dsd.es.northropgrumman.com/rf/ANALQ155.html The electronics and backward-wave-oscillators (BWO's) were in a bath of DC200. (http://www.clearcoproducts.com/pdf/pure-silicone/np-psf-6.pdf) When the system came on the DC200 was circulated through much of the electronics and high end systems, and then out and through a radiator that supported two jammers. The radiators then had ram air passed through them to supply cooling. Incidentally, it was huge amounts of fun to stand on a sheet of ice (northern tier SAC base) and as half of a two man team, pick up these 275+ lb beasts and load them into the belly of the aircraft, connect up antennas, and cabling. Often times even with or above our heads (at 6' tall). A the memories. Great stuff. Don't get me started about Desert Shield / Storm... 73 de K4DGW David Wilburn [EMAIL PROTECTED] Mike Markowski wrote: [EMAIL PROTECTED] wrote: In a message dated 1/23/07 2:08:47 PM Eastern Standard Time, [EMAIL PROTECTED] writes: I've been thinking about a water cooling system for my computer instead of noisy fans http://www.tomshardware.com/2003/12/30/5_ghz_project/index.html Anything worth doing is worth overdoing 73 de Jim, N2EY A messier but cheaper alternative: http://www.markusleonhardt.de/en/oelbilder.html and you can cook your french fries when you're done.

Just add a one-way valve. And the heat and gravity will do the rest (like a coffee pot).

Then there's Tygon tubing woven in-and-out of the fins, a bucket of water... with ice cubes? ... and an aquarium pump. (;-)) To be realistic ... a 12V computer fan from Radio Scrap with four sitck-on felt pads resting on top is really easy and inexpensive. 73!

Re: [Elecraft] PA cooling
I know.I've been thinking about a water cooling system for my computer instead of noisy fans...with a goal of a silent, or almost silent, PC. Thought this may be interesting to try with the radio as well.

Cool! If they can overclock a CPU to 5 GHz, perhaps we can coax 200W out of a KPA100.
