Re: [Elecraft] KX3 and Heatsink

Several years ago, I published a short article and accompanying video comparing the original KX3 heat sink to the CoolerKX model including a basic report on cooling performance. This one has since been discontinued, but is similar in design to the PAE KX32 model. I never obtained the updated

Does it do this if you transmit a long carrier into your antenna using the tune button? Can you transmit FT8 into a dummy load OK? John KK9A N4ST wrote: So, received a new KLPA3A & KPA3A from Elecraft in exchange for my old ones plus $$. Installed the new KLPA3A & KPA3A and passed LP and

Re: [Elecraft] KX3 and Heatsink

Bill, If you run 12 watts on AM, FM and digital then the supplied heatsink (assuming it is the newer heatsink the wraps around the bottom of the KX3) then it should be adequate. If you want to run the full 15 watts on those modes, I would suggest adding the Pro Audio Engineering heatsink for

Re: [Elecraft] KX3 and Heatsink

Yeah, what Eric said. Elecraft says, in the "Output Power" specification: "5 W or less recommended for high-duty-cycle modes (FM, AM, DATA). Power will automatically be reduced if PA temperature or current limits are exceeded." The stock heatsink is generally adequate *within* that recommendation.

Re: [Elecraft] KX3 and Heatsink

When you say " Elecraft-supplied heat sink" do you just mean the little heat spreader plate? The factory provided thermal solution is totally fine unless you want to run high duty cycle modes at full power. I have the proaudio ultimate (

Re: [Elecraft] K3S - High SWR on 6 Meters

What is the 6m antenna, how far away is it from the xmitter? Sounds like an issue with a balun or matching overheating with the stress of FT8? I would hook the K3 up directly to the 6m antenna or the dummy load.  Something is certainly acting odd. W0MU On 6/13/2022 2:07 PM, N4ST wrote: So,

[Elecraft] KX3 and Heatsink

Folks: I have a recently-purchased KX3 that includes the Elecraft-supplied heat sink. Is there any opinion of this does an adequate job compared to the ProAudio one? Thanks, -- --w8lvn-- __ Elecraft mailing list Home:

Re: [Elecraft] K3S - High SWR on 6 Meters

> Any advice? > A spur/oscillation in the KPA3A? > A relay stuck/not switching? Are you sure there is no breakdown in your antenna, feedline or external antenna switch? Infinite SWR on the external meter would indicate an issue beyond it. Are you seeing the problem on any other band? with

[Elecraft] K3S - High SWR on 6 Meters

So, received a new KLPA3A & KPA3A from Elecraft in exchange for my old ones plus $$. Installed the new KLPA3A & KPA3A and passed LP and HP TX Calibration. My 6M beam measures 1.06 SWR on analyzer. CW Key down, 100W, I get 1.2 on external SWR meter and 1 bar on K3S SWR meter. With FT8 I'm OK for 1
