Elecraft KX3 - Increased Output Power with Latest Firmware Update

Downloaded the latest upgrade for the KX3 as mentioned here mainly for the ability to run PSK65 sometime.

Not game to try 15W, the KX3 gets hot enough with 5W when its 38C (100F) as it is.

Wintertime shall give it a run and see how 15W goes.

Yep me too. SSB is fine at 15w but not a chance I’d try that with a full duty cycle mode :smile:

I have a new cooling heat sink for my KX3, designed in house. It is a small aluminum gutter shape that hangs on the back of your KX3. You just take a couple of ice cubes from your drink and drop them in. When they melt you just dump the water and add more.

If you are in a heated contest you fill the gutter with dry ice or liquid oxygen.

OK, now I will stop…but it was fun to say it!

Aluminium and liquid oxygen can get a bit explosive. Probably best go for liquid nitrogen :wink:

KX3 + software upgrade + PSK31 + Water + Latent Heat of Vaporisation = a nice cup of tea
