Re: [Elecraft] K4 operating manual now available as both .pdf and .html
I never understood why Elecraft put out the PDF file as white text on a black background in the first place. It can't be printed, and if you have to read it online the html version makes more sense. It just seems lazy to me for them not to have converted it on their end.

Re: [Elecraft] KX2 temperature
I expect he meant “existed for the KX2/KX3”. The Heathkit SB-230 is conduction-cooled with a beryllium oxide thermal link to conduct heat away from the anode to the heat sink. wunder K6WRU Walter Underwood CM87wj http://observer.wunderwood.org/ (my blog) > On Aug 21, 2021, at 8:04 PM, Jim Brown wrote: > > On 8/21/2021 7:48 PM, Gary Memory wrote: >> I had no idea heat sinks existed. > > Heat sinks have been widely used since the introduction of semi-conductors in > the '50s.

Re: [Elecraft] KX2 temperature
I guess I misspoke. I have boxes and boxes of "heat sinks" that I've collected thru the years. I use them all the time. I'm constantly looking on eBay for a size or two, for a given project, almost on a monthly basis. I had no idea that after-market heat sinks existed specifically for the KX2. And they look very nice as well! But again, I've never thought to look until I saw this thread. My sincere apologies.

Re: [Elecraft] K4 operating manual now available as both .pdf and .html
In your print dialog box look for "print background" and make it unchecked. You could then print a white background as well as "print as a pdf." At least that's how it works on a Mac OS.

Re: [Elecraft] KX2 temperature
I had no idea heat sinks existed. But, I've never looked, I suppose. Looks like a good idea, but I'm guessing the radio will no longer fit in its case. I ordered a set of heat sinks to try 'em out. My process to deal with the heat is perty much what Brian said. Thanks for the thread! I learn, I win. Gary, N7BRJ On Sat, Aug 21, 2021 at 8:23 PM Brian Hunt wrote: > I believe the trip temp. is 60c.

[Elecraft] Elecraft CW Net Announcement
Good Evening, The weather vane switched directions, winds from the ocean instead of from the smoke filled valleys. Cooler, with clouds most mornings. Temperatures have moderated to the mid 60s. Earlier today I saw a tan patch on the far side of my land. It resolved into a black tailed doe grazing beside the road. Then a fawn appeared beside her. A minute later a second fawn showed up about twenty feet away. Twins are common. They were browsing on my neighbor's land where the greenery is more mature. In a few years my land will recover from the disturbed soil plants filling the thinning scars. The soil will become more complex with a variety of mycellia. The sun was blank for two days this week. There was some activity on the far side. Solar flux is slightly higher. The ionosphere may support comms but they will be faint. I remember when we had better conditions, but that memory is old and faded. Please join us on (or near): 14050 kHz at 2200z Sunday (3 PM PDT Sunday) 7047 kHz at z Monday (5 PM PDT Sunday) 73, Kevin. KD5ONS - Do not try and bend the spoon, that’s impossible. Instead, only try to realize the truth… there is no spoon. https://www.quantamagazine.org/how-big-data-carried-graph-theory-into-new-dimensions-20210819/ __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
Re: [Elecraft] KX2 temperature
I believe the trip temp. is 60c. The rate you get there, of course, depends a lot on power setting, mode and ambient temperature. I’ve found at normal shack ambient I can cycle FT8 pretty quickly at 7 watts. But I always monitor PA TEMP and back it down if necessary. At the beach with a 55f breeze - no problem It’s a great little rig.

[Elecraft] KX2 temperature
Team: I discovered that the KX2 will trip out if its temperature gets too high. Clearly, this is a good thing. I am considering getting the heat sinks for the side. I now run with the temperature displayed. My question in relation to this is: is there a fixed temperature that it will trip out at? Alternatively, what is a good threshold to observe to avoid over-temperature operation? The manual does not seem to be very specific. Thanks for a great radio (I have it in my office upstairs with a wire to a tree, and get on the air between meetings.) and for a great forum. -- --w8lvn-- __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
