Re: [Elecraft] help with improving transmit eq

It just could be a mike issue that EQ won't correct. Otherwise, the values should show positive or + amounts starting with about 200 Hz. You might also check to see the previous owner had not set other values. 73 Bob, K4TAX K3S s/n 10163 On 2/3/2016 12:09 AM, Steve Wilson via Elecraft

Re: [Elecraft] help with improving transmit eq

Steve, Since this K3 is 'new to you', you can't know how the prior owner has set things. Check the settings in the TX EQ first. I would suggest that you initially set all bands to flat. For communications quality, normally you want to reduce the first 2 bands to the lowest settings and the

Re: [Elecraft] Quiet fans for K3

You can BEND the laws of physics, but you can't break them. Within the package size dictated, you can only move so much air in a given timeframe, "silently". Quiet is at very best a secondary consideration when spec'ing a fan to protect a multi $K transceiver. If you are really interested in

Re: [Elecraft] Quiet fans for K3

So, what is noise? It's energy. Some of it goes into the fan and moves air, some is from turbulence off the blades, and some heats the bearing. There are quieter fans that still move lots of air. They have carefully shaped blades and all of the flashing is cleaned off so the edges are
