Re: [Elecraft] Any larger or more efficient heatsinks available for the K2/100PA (radio lid/top)
My point is to avoid using fans to cool this radio so as not to aid in depleting the batteries in this emergency radio go box, while creating additional noise for the operator. I'm on the fence as whether to take this K2/100 down to a machine shop and see what they can do to place a more adequate heat sink on it, or instead just install my Yaesu FT100D. In the past, I had purchased a 3 1/4 size fan to cool the K2/100, but it wasn't enough. I then purchased a second one and ran them both to keep the heat manageable. In doing so, the whine/noise that the fans had created had forced me to operate with headphones. This was a very annoying experience. I think a larger heat sink will work for me, I simply need to find if any such animal exists for this radio (lid configuration). Thus why I posted here. Thank you all who have responded. I appreciate your time and knowledge shared. My hope is to use my K2/100 in my emergency radio go box. I love the radio in every other respect, except for the issue of it dissipating heat.

I stuck an old computer brushless DC muffin fan down over the warmest part with a little square of velcro, blowing down. I could run 100W [generally didn't but could] and the heat sink stayed almost cool. I don't think you have to move very much air over it to keep it cool. 73, Fred K6DGW - Northern California Contest Club - CU in the 2014 Cal QSO Party 4-5 Oct 2014 - www.cqp.org[http://www.cqp.org] On 9/28/2014 12:18 AM, Jim Brown wrote: On Sat,9/27/2014 5:54 AM, Don Wilhelm wrote: Take a look at the K2 Auxiliary KPA100 Cooling Fan Yes.

[Elecraft] Sorry . . . For some reason the text I'm typing into the body of my emails to this reflector is being stripped off. Weird, looks fine in my SENT folder.

[Elecraft] Attempt #3 - Any larger more efficient heat sinks for the K2/100 Lid PA?
Sorry, my email GUI by default was sending emails in HTML which does not get processed by the reflector here. Thus why there was previously no information except for title in my previous posting attempts. Noob here. Here is my original email as I had composed it. -- I quit using my Elecraft K2/100 when I kept getting burned on the PAs heat sink. This is both before and after having sent it in to get a check up. I would like to place this radio in my emergency radio go box, but instead of adding fans which will just suck my batteries dry pre-maturely, is there a larger more efficient heat sink available for this amp (radio lid) which won't lead to too much macgyvering? Thanks for any assistance you may be able to provide in advance ! As a note, I'm using an external KAT100 and have always kept the match down. I always use mono band resonant antennas which I'm anal about tunning dead on and not operating into an antenna with a match anything more than a 1.5:1, and that's before connecting the KAT100 antenna tuner to it. Please, if anyone can provide me with a larger heat sink / solution to cool down this radio, I would be extremely grateful !
