Re: [Elecraft] Power output on higher bands
Hi, Ah, of course. Your radio wasn't working well on the bands using upper sideband because of the filter offset! Very clever of Elecraft support to pick that up. I am glad you got it sorted out.

Re: [Elecraft] Power output on higher bands
Just as an update, I got it all fixed, thanks to Keith and Gary at Elecraft support. I only have the 1 filter that came with it, and the "offset" wasn't set inside the k3 utility on the filter settings. I set the offset like it was supposed to be, re-ran the tx calibration and everything is running perfect. What a great experience it was to build this from the ground up, and get it on the air. Just minutes after the fix I got 2 new DX countries on 20m! Thanks Elecraft!!

Re: [Elecraft] Power output on higher bands
Mike, Are you transmitting into a dummy load, or into an antenna. If you are transmitting into an antenna, I have to ask - what are the characteristics of your antenna on each band that you make reference to - I need to know the resistance and the reactance, not just the SWR. 73, Don W3FPR On 3/1/2012 8:04 PM, Mike Anderson wrote: > I've noticed some weirdness with transmitting on higher bands on my > elecraft. > > Down on 40, and 80, its great.

What is the radio? There are several possibilities...
