Re: [Elecraft] TUNE power, low vs high

I look at it another way. When I operate QRP I want every milliwatt I can have going to the antenna. As Ron’s post noted, a 2:1 SWR may be indicated as 1.1 when low power is used. That means you are losing significant power, but don’t know it. It teas a short time to crank the power up to 5 or 1

Re: [Elecraft] TUNE power, low vs high

Many years ago I built a circuit which used op amps to make diodes into "perfect rectifiers" -- rectifiers that would be linear at very low voltages. Antenna analysers also have the same problem. The real problem may be building a rectifier that works at very low voltages when at low power and

Re: [Elecraft] [KX3] Hi Curr Warning

Hi Ron, Thanks for your response but could you clarify. On the 12/10m bands I'm not sure of the VSWR of the antenna, but the VSWR reported by the ATU was 1 to 1, so basically the amp was perfectly matched and should have been OK. Now the fact that I had the radio set for 10W rather than 8W o

Re: [Elecraft] TUNE power, low vs high

Arno, your original message caught my eye. Many SWR bridges become very inaccurate at low power settings, so I tried my KX3 into a 2:1 load (25 ohms instead of 50). The SWR did change but only slightly. It was 1.1:1 at 0.9 watts and 1.2: 1 at 5 watts. That isn't enough to care about. Indeed, anyt

Re: [Elecraft] TUNE power, low vs high

Thank you, Don and Jack, that makes sense. To explain a bit more, I only operate portable, so my antenna situation is practically never the same and I need to tune anew. For my wire antennas I use the ATU. If I use the magloop, I bypass the ATU and use the TUNE function. That is where I reduced

Re: [Elecraft] [KX3] Hi Curr Warning

Not just "low" antenna impedance, but high SWR. The output stage is less efficient when the SWR is high so it draws more current to produce the requested output. 73 Ron AC7AC -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of G

The answer is pretty simple. The higher the output power, the more resolution for both forward and reflected power measurement. When calculating SWR we can get some pretty small reflected power values that may still produce a pretty high SWR. In order to get something that provides reasonable re

[Elecraft] TUNE power, low vs high

What could be the difference for the tuning result between tuning at, say, 0.8W vs at 3W? If there is no difference, why is the ATU tuning set to 2 or 3W, and not lower? I am thinking that a random length antenna with a potentially high SWR will tax the PA more at higher outputs. So why should

Hi Joel, Weight, on an Elecraft radio, is a ratio of the Dit and symbol space time. With weight set to 1.00, the Dit period is the same time as the symbol space time. As weight is increased, the Dit, and Dah, times are lengthened by the ratio. For example, 25 WPM, the Dit time, in ms, is defined a

Like anything, you weigh up the benefits against the costs or your ability to 'do' something else. Personally, as a left handed keyer, the Palm radio side unit isn't a great help, neither is the thin strip of metal and tape idea, as I'd need them on the side of the radio with all of the sockets..
